->''"Everything Myth/{{Merlin}} did, my Lady, had another explanation."''
-->-- '''Derfel Cadarn''', adopted son of Merlin, ''Literature/TheWarlordChronicles''

Sometimes you track down the monster and pull the rubber mask off to [[ScoobyDooHoax reveal the janitor]].

Sometimes you try that, and [[RealAfterAll the monster gobbles you up]].

[[RiddleForTheAges And sometimes you don't get either way. You are left with nothing except the tracks, the sightings, and hypotheses.]] Two characters can argue for the alternative explanations, supernatural or naturalistic, without either one of them carrying the IdiotBall.

How this is done affects any reaction to it. Sometimes it invokes TheChrisCarterEffect or KudzuPlot. Sometimes it is an eminently satisfactory way to create an open ending (generally when the question has not been [[DrivingQuestion the focus of the plot]]).

A common effect is to offer a mundane explanation of how something ''could'' have happened, but not in fact establish that is how it ''did'' happen. (Such as never trying to eliminate the purported cause and establish that the effect does end.)

The verifiable presence of magic in the world does not preclude this trope; in {{Fantasy}} works, this may come into play for divine intervention, or rare forms of magic (vs ordinary forms as well as mundane). Or some magical things may be clearly magical, and others more ambiguous. Conversely, the presence of high technology or other ''non''-magical special powers extends the possibilities of this trope by allowing a greater range of "mundane" phenomena. It can also effectively come into play when characters ponder whether an effect was natural or extremely high tech.

Usually the author won't [[ShrugOfGod confirm or deny]] a solution. If they do, see DoingInTheWizard (or [[DoingInTheScientist Scientist]]), {{Jossed}}, MagicAIsMagicA, all of which tend to exclude this trope.

Often comes into play with AngelUnaware, and does when [[ThereAreNoCoincidences characters say]] BecauseDestinySaysSo about situations that could be interpreted as ContrivedCoincidence. Any apparent DeadPersonConversation (particularly if TalkingInYourDreams) may fall under this, if the conversation contains nothing that the character could not have known. PropheciesAreAlwaysRight does not preclude their looking like dumb luck.

SubTrope of RiddleForTheAges. SuperTrope to OrWasItADream.

Compare AmbiguousEnding; and [[http://en.wikipedia.org/wiki/Fantastique Fantastique]] (from TheOtherWiki), a genre of fiction typified by supernatural phenomena that is not explained to the reader or the main characters, hinting at a magical occurrence.. Also compare ThroughTheEyesOfMadness, where the audience sees evidence in favor of the weird explanation, but remains unsure of whether it's real or not because of the possible [[UnreliableNarrator unreliability of the narrator]].

Contrast RealAfterAll, which often involves a mix of mundane and magical explanations, but usually makes it clear at the end which incidents were which (at least to the audience, GaveUpTooSoon is common for the characters).

[[folder:Anime & Manga]]
* Chiyo's parentage in ''Manga/AzumangaDaioh'' falls into this. Both Osaka and Sakaki dream of her father being a "cat creature" which is also encountered in the waking world as a stuffed animal. When scenes are shown of Chiyo interacting with her family, her parents are neither seen nor heard (Chiyo's lines to them are typically the sort of declarative statement that would not require a response, and the scenes end before they would have time to speak). Thus, while one possibility is that she has parents like the other girls who just never appear on-camera, there are also the distinct possibilities that her parents are imaginary or that her father is, in fact, the cat-creature.
* Goshiki Agiri from ''Manga/KillMeBaby'' is a ninja, yet most of the actual ninja tricks she uses are either obviously accomplished or purely jokes.
* ''Manga/HayateCrossBlade'': Did Wanko REALLY curse those two girls in her debut fight, or did they just freeze from fear at her sheer creepiness?
* ''Anime/SoundOfTheSky'' thrives on this. Are the main religions right and "Them" were supernatural beings? Are the ghosts real, or just a hungry owl and a PTSD induced hallucination?
* Some of the things Break does in ''Manga/PandoraHearts'' fall into this. We've seen him use actual magic to bind Alice right at the beginning. But he also produces things from nowhere (or out of his hat) which could be illusions or could not. And is Emily ventriloquism or something else?
* This trope is a major theme in ''LightNovel/GroundControlToPsychoelectricGirl''. The title character, Erio Touwa, believes she's an alien and eventually secludes herself from almost all human contact. Then her cousin Makoto Niwa moves in due to his parents having to work outside of Japan, and he brings her back to reality. She slowly starts to reintegrate into human society, and then a strange girl named Yashiro Hoshimiya appears and berates him for causing her to stop believing in aliens. He constantly ridicules her as well, thinking she's got the same psychological issues Erio went through. At the end of episode 13, Yashiro tells Makoto to move slightly from the position he's standing in. Shortly after he does, a meteor crashes into the exact spot he was just standing in, causing him to wonder if she really was telling the truth about being an alien.
* ''LightNovel/DenpaTekiNaKanojo'': The BecauseYouWereNiceToMe scene that is RememberedTooLate by Juun could perfectly explain Ame’s PastLifeMemories of being King Juun’s knight. However, ''it could not explain'' the PsychicLink Ame has with Juun.
* In ''Manga/{{Berserk}}'', the Hellhound entity that resides within Guts. Its presence being hinted in the early Black Swordsman Arc and having a full physical debut in the Lost Children Arc, fans speculate ''what'' the Hellhound is and ''where'' it exactly came from. Is it an independent spirit that latched onto Guts during the Eclipse event, or is it merely a trauma-induced hallucination spurred by the traumatic Eclipse? Is the Beast a separate and malevolent force that has always resided within Guts since birth, or is the Beast in fact ''Guts himself'' and is just an anthropomorphization of his darker nature? As the setting of ''Berserk'' has ClapYourHandsIfYouBelieve in full effect, it '''could''' have started out as an abstract idea but then [[{{Tulpa}} took a life of its own through Guts' constant contact with the supernatural world]]. We just don't know what the Hellhound is and might never know.
* ''Manga/DeathNote'':
** In the manga's final chapter, it's noted that [[spoiler:Mikami mysteriously died in prison ten days after Light's defeat, leading Matsuda to theorize that Near wrote in the Death Note so as to restrict Mikami's actions, enabling Light's conviction. The anime includes no such speculation from Matsuda, and Mikami instead commits suicide on the spot, casting doubt on a supernatural interpretation]].
** Then, there was that part where Light's archenemy L appeared during his death, both staring at each other and lampshading L's own death. This almost drove fans insane with their theories, riots and flame wars. Although the author has made it quite clear that the afterlife doesn't exist in the ''Death Note'' mythos [[labelnote:*]]although one of the rules of the notebook indicates that there is a Heaven and Hell, so...make of that what you will[[/labelnote]], there are still speculation that it wasn't Light's hallucination but L actually staring at him supernaturally.
** The notebook itself is a subject of debate. Does it contain some sort of sentience that can actually [[TheCorruption bring out the worst in people's egos]], or is it just an (extra)ordinary notebook?
* The title dog of ''Anime/JunkersComeHere'' [[TalkingAnimal can speak]] and is able to grant ThreeWishes to his owner, Hiromi. By the end of the movie [[spoiler: he loses his ability to speak and is now a normal dog]] and Hiromi wonders if Junkers was really a talking dog and if everything that happened was because of his magic or just a series of coincidences.
* The encounter with Heike Shige in ''Anime/SamuraiChamploo'' may have been the result of the accidental ingestion of psychedelic mushrooms, or he and his men may have actually been undead. There isn't really anything that confirms or debunks either theory, and no mention of the incident was made after that.
* Ryou from ''Manga/BokuraNoHentai'' can see his dead sister's ghost. It's left ambiguous whether she's real or not [[spoiler:but it's implied he's hallucinating it and it's his subconscious]].
* A number of things that BigBad Altena does in ''Anime/{{Noir}}'' don't seem possible unless she has some manner of magical/psychic powers, with one scene in particular involving her watching three candles that represent the "saplings" or candidates for her plan to recreate the titular Noir, a duo of two girls who "govern death" on behalf of an AncientConspiracy. When one of the candles goes out [[spoiler:representing how one, Chloe, has just died]] Altena not only seems to know ''what'' it means but ''which'' sapling it was referring to. Not to mention how Altena is generally pretty unsettling and vaguely supernatural, and lives in an EldritchLocation somewhere between Spain and France that happens to feature [[spoiler:an active '''volcano''']].
* It's left vague if [[spoiler:Yuuki post-episode eight]] in ''Anime/TokyoMagnitude8'' was a ghost or [[spoiler:Mirai]] hallucinating. [[spoiler:He did have hope Mari's daughter was alive even though he saw her presumed daughter's body]], which could mean he has a knowledge of the dead, and we see him disappear later. However it's possible that was all in [[spoiler:Mirai's]] head and she was imagining what [[spoiler:Yuuki]] would do.
* In ''Manga/PeachGirl'', an otherwise fairly realistic slice-of-life/Drama series, resident AlphaBitch Sae sometimes displays... interesting abilities, such as becoming paper thin, usually when she'd depressed. You'd just chalk this up to artistic effect, except sometimes it ''affects the plot'' - She walks right past a security guard by turning wafer-thin and hiding when he tries to stop her, and he reacts as you really would in that situation. Another time she hides under a box no human could reasonably fit into, by once again, slimming herself down.
* The main point of Miki Yoshikawa's one-shot ''The Demon's Classroom''. An elementary school class gets a new teacher who claims to be Diablo de Mon, the former king of the underworld. At first, he acts quite weird and seems oblivious to the customs of human society, making the kids think he really ''is'' a demon. When they decide to try and bust him as a demon, they are unsuccessful as now he acts like a normal human. By accident, they set fire to his house, and the next morning, the house is whole, and de Mon himself is unharmed. He claims he used his powers to nullify the fact that the fire took place. Then the main character notices that he has burns on his hands. At the end of the story, the narration states that the kids grew to like de Mon, but never actually found out if his claims were true.
* Until now ''Manga/SchoolLive'' made readers wonder whether Yuki did actually see [[spoiler:the ghost of her teacher, Sakura-sensei AKA Megu-nee]]. The readers know that Yuki is delusional and an UnreliableNarrator (and that [[spoiler:Megu-nee is DeadAllAlong]]), so the most likely explanation is that it's just another hallucination. However, the apparition always seems to know what's going on and to actively help the girls. It's also implied somewhat that Yuki's helpful (if apparently strange) suggestions come from her.
* The ending to ''Manga/YourLieInApril'' has [[spoiler:Kaori's death]] happen during a piano performance of Kousei's. It's left vague if [[spoiler:her playing the violin alongside him and later [[DisappearsIntoLight bursting into light]]]] is another one of the artistic interpretations from Kousei's head while he plays music, or if [[spoiler:that was really Kaori's spirit playing one last song with Kousei]].
* ''Manga/JojosBizarreAdventureDiamondIsUnbreakable'' has Mikitaka Hazekura, who claims to be an alien with VoluntaryShapeshifting powers and a weakness to loud-noises like sirens, but when Josuke meets his mother she says he's just an ordinary boy who's obsessed with aliens. The series deliberately avoids revealing if he's really an alien or just a very eccentric human being whose abilities come from a [[FightingSpirit Stand]] (which is Mundane by ''[=JoJo=]'' standards).
* ''Tsukiuta'' abuses this trope. It's an [[IdolSinger idol anime]], following two six-member boy bands. Shun, the leader of one of the groups, is known as the "demon king", and sometimes seems to have supernatural powers... but it never goes into whether or not this show takes place in the real world, or some sort of world where that's possible. And then there's the ''one episode'' featuring the female equivalent group - who, apparently, are magical goddesses-in-training ''from the moon''. And the boys don't know.

[[folder:Comic Books]]
* At one point of ''Franchise/{{Superman}}'' storyline ''ComicBook/KryptoniteNevermore'', Superman confronts a villain who uses an ancient artifact -- called the Devil's Harp -- to steal powers and abilities. After breaking the Harp, Superman ponders on its nature: Was it a magical device? Or just a piece of forgotten technology? He concludes that he will never know, the story does not tell, and both answers are possible in this setting.
-->'''Superman:''' I guess we'll never know what this thing was! Magic -- or the relic of some forgotten science -- or how it took musical talent from Timos Achens and super-powers from me! A pity... such a device could have been a great good!
* ''Franchise/{{Batman}}'':
** The villain Scarface, a ventriloquist dummy mob boss, is sometimes teased as something more than a delusion of an unstable mind. The Ventriloquist himself believes that the dummy is possessed by the spirit of a gangster rather than a facet of his own personality; since it was cut from wood of a tree that in the past was used to hang criminals, it is a rather spooky origin for a seemingly mundane puppet. How "real" Scarface is also depends on the continuity. In some, the Ventriloquist is able to free himself of Scarface's influence via therapy; in others, all it takes is destroying the doll.
** Zigzags in ''ComicBook/BatmanTheCult'' with BigBad [[SinisterMinister Deacon Blackfire]], who claims to be a 500-year-old Native American mystic. On one hand, his methods of recruitment are clearly shown to be based on psychology and drugs, just like documented cults. On the other hand, evidence suggests Deacon Blackfire really was immortal. Whether he was a complete fraud or merely a partial fraud is never fully explained.
** ''Batman'' as a whole tends to take this approach to the nature of Gotham City itself and Arkham Asylum in particular. Is the city cursed, plagued by demons, tormented by ComicBook/{{Darkseid}}'s Omega Power, by nameless [[EldritchAbomination things]], or is it just an incurable WretchedHiveOfScumAndVillainy all on its own? Hints at various supernatural origins for the city's woes and the Asylum's troubles come and go, but none are ever confirmed and there's always a mundane or comic-book-mundane explanation for everything else.
** ComicBook/BatMite's whole ComicBook/PostCrisis existence. Two stories by Alan Grant show Bat-Mite appearing to a criminal named Overdog. Both times Batman (who doesn't find Bat-Mite) rationalizes that these were just Overdog's drug-induced hallucinations, but the reader is left wondering...
* ''ComicBook/GlobalFrequency'' #5, "Big Sky", revolves around the appearance of a spectral, otherworldly being referred to as an 'Angel', which is powerful enough which drives the entire population of an isolated Norwegian coastal town mad. The team eventually discover a mundane explanation involving the burning down of a local church and resonance around local rock formations which caused sensory overload -- but then, after they've identified this explanation, one of them floats the possibility that the appearance of a ''real'' angel might have similar effects involving similar probabilities.
* ''Franchise/SpiderMan'':
** ''ComicBook/JMSSpiderMan'' introduces a character named Ezekiel that claims that Peter's powers aren't a mutation caused by an [[ILoveNuclearPower irradiated spider bite]] but are in fact "totemic" powers carried by the spider which it felt compelled to pass on after being hit by the lethal radiation beam. It was written in a way letting it be totally ambiguous if either this version or his classic origin is the real one, and even suggesting that both might be true to some extent. When Spider-Man asks an ally of Ezekiel which explanation is true, he simply responds that one explanation didn't necessarily contradict the other.
** When the original Mysterio came BackFromTheDead, he appeared to have supernatural abilities, supposedly gained in Hell. Given that he was already a MasterOfIllusion, it's impossible to be sure how real these powers were, and in the post-''ComicBook/OneMoreDay'' timeline they haven't come up.
* The antagonist of the ''ComicBook/BlakeAndMortimer'' book ''The Sarcofagi of the Sixth Continent'' claims to be the ancient Indian emperor Ashoka the Great, who first "resurrected" while Mortimer was a young adult to help free India from British rule and later during the "present" to torment the 1958 World's Fair. While it turns out that [[spoiler:there is some LegacyImmortality at play since the present Ashoka is actually the daughter of the one Mortimer met in his youth, the identity of the latter is never revealed. Also, they never explain his albino monkey guardians that can be summoned via a puff of smoke]].
* Creator/AlanMoore's ''ComicBook/{{Providence}}'' deals with this trope and hangs a {{Lampshade}} on it. The approach to Lovecraftian horror in the books is to present it this way to Robert Black, while the reader knows the truth. Robert Black, being an aspiring writer, lampshades the trope by describing it in his commonplace book at the end of Issue 4:
-->'''Robert Black:''' Now, if something supernatural were to actually occur to someone in real life, anyone normal would just run a mile. They wouldn't have the author and reader's interest in unraveling the mystery and getting to the story's end. They'd simply flee. I know I would, and I like to think that I'm a normal person underneath it all. I suppose the only way to handle it realistically is to rely on people's tendency not to believe that anything out of the ordinary is going on, even if evidence is mounting to the contrary."
* ''ComicBook/PunkRockJesus'' reveals towards the end that [[spoiler: Rebekah, secretly the protagonist's sister]] was given a massive dose of drugs and appeared to be drowned as an infant. The characters of Thomas and Sarah briefly debate if her survival was a scientific anomaly or a religious miracle. The readers are left to decide for themselves.
* ''ComicBook/TheUltimates'' began with an unclear origin for the powers of Comicbook/TheMightyThor. Is he a real God from Asgard, attacked by a rival god with reality-warping powers? Or just a madman with delusions of grandeur, who stole high-tech weapons produced in Europe? In the first two story arcs, both options seemed plausible to the reader. The final answer only came at the end of the second arc: [[spoiler:he's the real deal.]]
* Until one particular infamous story (regarded as non-canon by much of the readership), this is how the supernatural was handled in ''ComicStrip/ThePhantom'' (the one who lives in the Skull Cave in the Deep Woods surrounded by the Bandar pygmy poison folk). Any time something supernatural was depicted, there was always an alternative "natural" explanation such as magic tricks, illusions or hallucinations caused by fever or gas.
* The Annual issue of ''ComicBook/TheTransformersMoreThanMeetsTheEye'' keeping with its close look at Cybertronian religion. Did the ground in Theophany give way by chance, or was it in response to Drift's plea? Was everyone teleported to safety because the Metrotitan's faith in the Cybertronian race restored after Rodimus' selfless act, or was it because he got the energy to do so after some of his mass was displaced? Did Ore disappear because Primus sent him to the Afterspark, or, as an extension of the Metrotitan (having been temporarily resuscitated by him), did he teleport along it? Was it something else? We'll never know.
* In ''ComicBook/JohnnyTheHomicidalManiac'', it's never entirely clear whether Johnny's house is home to an EldritchAbomination and a set of [[SealedEvilInATeddyBear demonic dolls]], or if he's a [[TalkingToThemself schizophrenic]] [[ThroughTheEyesOfMadness psychopath]]. WordOfGod seems to support [[TakeAThirdOption both]] [[YourMindMakesItReal at once]]
-->'''Johnny''': It's possible I'm quite horrendously insane.

[[folder:Comic Strips]]
* ''ComicStrip/CalvinAndHobbes'':
** Is Hobbes a real person, or (as most people around Calvin think) just a stuffed animal subjected to Calvin's vivid imagination? Careful attention reveals that instead of both being possible, ''neither'' is: Calvin could hardly tie himself to a chair, for instance, which Hobbes has done to him (on request).[[note]]This was viewed by Calvin's father. So it's not just Calvin's imagination.[[/note]] On the other hand, photos of Hobbes in action show only a stuffed tiger. The best we're likely to get is the author's comment that "Calvin sees Hobbes one way, and everyone else sees Hobbes another way. I show two versions of reality, and each makes complete sense to the participant who sees it."
** This comes up with some of Calvin's other apparent fantasies, too. In one series, he creates several duplicates of himself; no one besides him and Hobbes sees more than one Calvin at a time, but his mother seems a bit perplexed at how she keeps finding Calvin in unexpected places. On the opposite side there are also fantasies that have very mundane solutions that are pointed out, such as when Calvin imagines a baseball coming to life and chewing up his bat, Calvin's father points out the mundane idea that Calvin had been hitting rocks with it, despite Calvin clearly being scared...
* In ''ComicStrip/{{Peanuts}}'', does Snoopy's dog house really fly, or is it just his imagination? There's also the question of how it can be BiggerOnTheInside, and how he got all the stuff that is supposedly inside it; [[TakeMyWordForIt claims have been made by him and other characters]] that it contains a television, pool table, a book collection, and even a Van Gogh (which he replaced with an Andrew Wyeth after the dog house was destroyed in a fire).

[[folder:Fan Works]]
* In the ''VideoGame/HeroesOfTheStorm'' fanfic ''FanFic/HeroesOfTheDesk'' it's not quite clear what items in the Strategic Prevention, Extraction, and Ablation Regiment's arsenal are actually MagicByAnyOtherName versus simply being [[ClarksThirdLaw too advanced for "outsider" science to comprehend]]. There are some items which fall under AluminumChristmasTrees and would presumably be more advanced versions of actual concepts, and then there are other 0-10-4s where [[SufficientlyAnalyzedMagic despite best efforts]] the best SPEAR can come up with is AWizardDidIt.
* Happens in the ''Radio/OurMissBrooks'' fan fic [[https://www.fanfiction.net/s/10203524/1/Our-Miss-Brooks-The-Reunion-Assembly The Reunion Assembly, Chapter 13, "Connie Dreams."]] Connie dreams that the long-deceased Mrs. Davis and Mr. Conklin pay her a visit. AllJustADream OrWasItaDream?
* Done 'masterfully' in [[http://www.fimfiction.net/story/85411/reflections Reflections.]] The fate of the dead are left intentionally vague with enough to support either viewpoint.
* Hobbes' revised backstory in ''Fanfic/CalvinAndHobbesTheSeries'' is as ambiguous as can be - Calvin's mom put him in the trap, but she found him laying on their property, looking brand new.
* In ''[[http://www.fimfiction.net/story/65940/my-little-mission-sneaking-is-magic My Little Mission: Sneaking is Magic]]'', it's left ambiguous throughout the entire story as to whether Snake really was transported to Equestria or whether the entire thing is an illusion happening in his head. [[spoiler: It's implied that Ocelot traveled to Equestria too which would mean that Snake really did go there, but it's never confirmed.]]
* Explicitly how Gnome magic functions in ''FanFic/StrikeWitchesQuest''. this is doubly hilarious due to the explicit {{Magitech}} and MagicAIsMagicA of witches.
* [[spoiler:Loneliness]], the first BigBad of Season 1 of the ''Fanfic/PonyPOVSeries'' could potentially be a supernatural parasite, [[spoiler:a SplitPersonality of Trixie's]], a manifestation of Discord's magic, an EldritchAbomination, [[spoiler:Trixie's potential unawakened [[SuperpoweredEvilSide Nightmare]]]], a Shadow Of Existence attempting to steal [[spoiler:Trixie's]] Light to reconstitute itself, or simply a figment of [[spoiler:Trixie's]] imagination. Support is given for all possibilities and which if any is the actual origin is never explained, either in universe or by WordOfGod, who intentionally left it ambiguous to make her that much scarier, and she's thoroughly destroyed at the end of the fight with her, so there's no chance for the characters to find out.
* ''FanFic/ABriefHistoryOfHistories'': Usagi and Luna discuss this after Manga/SailorMoon saves her father, Chairman Tsukino, and he fails to recognize her. Usagi's convinced he ''did'' recognize her, but didn't want to acknowledge her because he [[ComplainingAboutRescuesTheyDontLike thought she wasn't brave enough during the fight]]. Luna reassures her that her transformation includes magic to protect her SecretIdentity. However, she's uncertain whether or not that's actually the case.
* Eric the Hedgehog in ''FanFic/SonicXDarkChaos''. Is he simply an eccentric and lucky IdiotSavant, or is he a HumanoidAbomination with the power of ClapYourHandsIfYouBelieve? Both explanations are implied in the story.
* FanFic/AngelOfTheBat is kind of all over the place. Aliens (e.g. Franchise/{{Superman}}, Comicbook/{{Supergirl}}...) definitely exist, magic (via Zatanna) definitely exists, God in some form or another definitely exists (as ComicBook/TheSpectre is mentioned) and [[spoiler:Deacon Blackfire was indeed immortal, as is his servant and BigBad The Seraphim.]] The ambiguous part is whether God is a kind figure, caring for his servants such as Cassandra or if she just imagined God caring for her and overcame her adversities herself. After overcoming [[spoiler: her CrisisOfFaith]] she admits everything she believes may just be a beautiful dream, but chooses to believe it isn't.
* Discussed in ''Fanfic/ReturnOfThePrimarchs'' when [[SuperSoldier Fulgrim]] crashes into a planet that remembers his murderous, demonic future version. Seeing that this Fulgrim is heroic, the leader of civilians says that either a miracle happened and past Fulgrim returned, or the man in front of him is a crazy Space Marine who convinced himself that he's the [[SuperSoldier Primarch]] from Great Crusade times.
* Partly why ''VideoGame/Metroid2'' [[{{Creepypasta}} Secret Worlds]] is so haunting. Is it all an elaborate hoax and the protagonist merely a sucker? Or was Palm really visited by [[spoiler: the ghost of Gunpei Yokoi?]]
* In the [[Manga/OutlawStar Outlaw Star]] fanfic ''[[FanFic/AFistfulOfDragonite A Fistful of Dragonite]]'' Aisha’s [[OurWerewolvesAreDifferent skinchanging ability]], if any, is showcased off-screen, and any witnesses killed quickly after seeing it. Whether or not she truly has supernatural powers is left to interpretation. WordOfGod is that this was set-up deliberately from the start..
* In Franchise/MassEffect's fanfic ''[[https://www.fanfiction.net/s/11073051/1/Resurgence Resurgence]]'', [[MassEffect2 part 3]] of the ''Parable'' series, Jane/Shepard often had SilentHill-esque nightmares that can all be explained as the symbolism of her various fears and regrets from the suicide mission. But in the last dream she had in that in that part where Jane was chased after by something with unnatural screams and wailing of like an infants, she was saved by two invisible beings whom she described as warm, protective, easy to pleased, and innocent. When she woke up, she just has been puked out from the Baby Reaper after her husband Garrus killed it and later, they discovered that [[spoiler: she's been [[HalfHumanHybrid pregnant]], with ''twins'']]. The author never explain more about it other than the fact that the whole thing was inspired by Silent Hill.
* ''The Sanctuary Telepath'', Janine's encounters with the supernatural. Did John and James really speak to her or was it her damaged brain's attempt to function after the loss of the [[PsychicLink psychic links]]? Did she remember the ''actual'' afterlife or was it just an illusion? She even admits her own UnreliableNarrator status, but chooses to believe in it anyway, because the other alternative feels unbearable... which again can be the product of her revived status or just good old human nature.

[[folder:Films -- Animation]]
* In ''Disney/{{Tangled}}'' -- Flynn and Rapunzel argue.
-->'''Rapunzel:''' Something brought you here, Flynn Rider... Call it what you will. [[BecauseDestinySaysSo Fate, destiny...]]\\
'''Flynn:''' A ''horse''.
* In Disney's ''Disney/TheHunchbackOfNotreDame'', it's ambiguous as to whether or not the gargoyles are sentient and capable of movement. It's possible they're just imaginary friends Quasimodo created to deal with his isolation. In the climax, [[spoiler:another gargoyle appears to come alive, scares Frollo, and breaks]]. Maybe they were RealAfterAll, maybe that was an unrelated hallucination.
* In ''WesternAnimation/ThePrinceOfEgypt,'' the Egyptian priests' magic is presented this way--they change their staffs into snakes in the middle of a huge VillainSong, with a bright flash that keeps the audience from seeing what actually happens. They also move impossibly far in parts of the song when the screen goes dark for an instant, but that could just be musical convention instead of in-universe magic. They also apparently summon floating glyphs and control flames with gestures during the same number. Earlier on, their presentation of Tzipporah in tribute to Rameses wouldn't be out of place in a modern magic show, apart from how "the Midian girl" is tied up for real. Them turning water into blood looks more obviously fake, though: they just add some powder that gives it a reddish tint. Of course, the point of the demonstration was to make Moses look like a deceiver.
* ''WesternAnimation/TheLegoMovie'' has an example that goes beyond the others; [[spoiler:Late in the film, it's implied that the whole adventure is just real-life human Finn's playing with his dad's Lego sets... but our hero Emmet is fully conscious and -- with some difficulty -- capable of moving a little while in the "real world".]]
* ''Disney/TheAdventuresOfIchabodAndMrToad'' deliberately leaves it ambiguous as to whether or not the HeadlessHorseman exists, unlike the book, which very strongly hints that the horseman was Brom Bones in disguise. Notably, the Horseman's horse is the same color as that of Brom Bones, and he also carries a sword identical to that Bones previously wielded. However, Ichabod does at one point look down the Horseman's coat and doesn't see anything, implying what he encountered was the real deal. In another scene the Horseman's horse jumps from an hill to another who was quite far from the former like it was flying. A thing that a normal horse wouldn't have done it.
* The ending of Disney's version of ''Disney/PeterPan'' leaves it ambiguous whether the adventures in Neverland were real or AllJustADream of Wendy's. Unlike in the original play and novel, where Wendy and her brothers spend many days in Neverland and come home to find their parents grieving their absence, here the trip lasts just one night, the children are already back home by the time the parents come back from their dinner party, and while they see what looks like the pirate ship sailing in the distant sky, it's purposefully drawn so we can't quite tell if it really is the ship or just a cloud formation. The sequel more or less confirms it to have been RealAfterAll, though.

[[folder:Films -- Live-Action]]
* In ''Film/ThirteenAssassins'', one of the characters is stabbed through the throat and has his stomach sliced open. He falls down, seemingly dead. At the end of the movie, he returns, only slightly bloodied, and explains that samurai swords are child's play compared to wrestling bears. In an interview, the director [[ShrugOfGod says it's up to the viewer to decide whether he was just a really tough guy, or if something supernatural had happened]].
* In ''Film/TheAbominableSnowman'', while it's pretty much certain that the yeti have a PsychicLink, it's not clear whether the climbing team's HearingVoices and whatnot is due to psychic meddling or to the fact that they're on a RiverOfInsanity voyage (or both).
* In ''Film/AvengersAgeOfUltron'', [[spoiler: Comicbook/TheVision lifts Mjolnir, a weapon that OnlyTheChosenMayWield]]. It's unclear whether this is because [[spoiler: Vision is worthy to wield the hammer (magic), or because he's an android and lifting the hammer is purely mechanical action (mundane). Thor believes the first, Tony thinks the second, comparing it to dropping the hammer in an elevator.]]
* Being a psychological horror film, ''Film/TheBabadook'' leaves a lot open to interpretation. It's more than possible that the RuleOfSymbolism is at play here, and that the entire story is allegorical [[spoiler:with the Babadook representing the power of grief, resentment and the strain of single parenthood and how the denial of these problems can consume you.]]
* [[Comicbook/{{Catwoman}} Selina Kyle]]'s 'powers' in ''Film/BatmanReturns''. The supernatural would definitely explain how a mousy assistant could gain the ability to actually hold her own against Batman and survive fatal falls ''and'' several gunshots. Then again maybe her brush with near-death simply pushed her over the edge and turned her into a combination of TheDeterminator and TheUnfettered, making her run on sheer will power.
* ''Film/{{Below}}'': Were the strange apparitions the result of high [=CO2=] levels or vengeful spirits? On the one hand they clearly weren't DeadAllAlong, on the other [[spoiler: ''something'' other than guilt brought them back to the site of the hospital ship they accidentally torpedoed and deliberately covered up]]...
* In ''Film/BigFish'', most of the things Edward Bloom says in his stories turn out to be [[spoiler: exaggerations based on things that actually happened (for example, Karl was indeed a giant, but not nearly as big as Will imagined him). However, we never learn whether seeing his own death in the witch's eye was real or not, as we never hear him say what happens]].
** ''Big Fish'' is an interesting case as it intentionally plays with this trope a bit. The stories in the beginning of the film are rather outlandish, but the further into Edward's life they are the more down-to-earth and less magical things get until his final stories are more likely. [[spoiler: This is supported with Jenny's version of Edward's second arrival in Specter, where she also seems to remember Karl as rather more giant than he actually is, though it does keep the magical element of the giant flood where Edward sees a mermaid.]]
* ''Film/{{Birdman}}'' ultimately leaves it ambiguous as to whether Riggan's telekinetic powers were real, although some parts heavily imply that he was imagining them, or at the very least exaggerating them.
* ''Film/BlackDeath'' ends like this, with [[spoiler: the witch taunting the protagonist that her "black magic" was really tricks and misdirection she used to control the villagers. This is particularly stinging because the protagonist had earlier killed his love interest after she had been "raised from the dead" as a mindless abomination... the witch implies she was merely heavily drugged and was never dead in the first place.]] It's left ambiguous as to whether this is the truth, or if the witch was simply lying to the protagonist to get him to lose his faith in God.
* ''Film/ChildrenOfTheCornIITheFinalSacrifice'' puts the supernatural stuff in the series in question by revealing that the current setting, along with [[Film/ChildrenOfTheCorn1984 the previous one]], has been exposed to contaminated corn that causes hallucinations for years.
* In ''Film/TheDarkKnightRises'', [[spoiler:Ra's Al Ghul drops in to have a chat with Bruce, despite having died at the end of ''Film/BatmanBegins''. It could easily be a hallucination, but Bruce gets relevant information from it that he didn't know. It would be easy to argue whether it was a hallucination or if Ra's actually is immortal. Though it does turn out that said information is false, so if Ra's was indeed around for that conversation, he's quite good at bullshitting.]]
* In ''Film/DarkMirror'', has the ghost of Elenor been possessing Deborah to kill these people, or is Deborah just going crazy? The disappearing bodies and the blood trail ending at the wall is suggestive, but not conclusive.
* ''Film/{{Descendants}}'': The villain kids make a LovePotion and wonder if the human tear to be used as one of the ingredients really needs to be generated by sadness. When Jay suggests using onions to force someone to shed tears, Evie offers a scientific explanation to believe it won't be the same thing.
* ''Film/LesDiaboliques'' ends with a kid claiming to have talked to [[spoiler:Christina, who died of a heart attack.]] The boy has a reputation of being a liar, so is he lying now? He ''did'' say the truth about [[spoiler:seeing Michel]], so did he actually [[spoiler:see a ghost?]] Or did [[spoiler:Christina survived her attack, just like Michel faked his death earlier?]]
* In ''Film/DontGoInTheHouse'' the VillainProtagonist hears voices that we assume are just auditory hallucinations, though as he's dying they call him a failure and say they'll find someone else. Before the credits role, another abused little boy is shown hearing similar voices.
* The film ''Film/DraculasDaughter'', despite being advertised as a sequel to the famous Creator/BelaLugosi ''Film/{{Dracula|1931}}'' film, remains maddeningly vague on whether the title character actually is Dracula's daughter. She's never seen doing anything overtly supernatural like Dracula in the first film, and [[spoiler:ultimately dies from a stake in the heart, something equally lethal to both humans and vampires.]]
** This is also true of ''Film/VampiresKiss'' and the early Creator/GeorgeRomero movie ''Film/{{Martin}}''.
* In ''Film/EvesBayou'', the main character uses voodoo to try and kill [[spoiler: her father]] for hurting her sister. [[spoiler: He]] does die at the end, as a direct result of Eve's actions, but it is never explained whether or not the voodoo had a hand in what happened.
* ''Film/TheExorcismOfEmilyRose'': Was she possessed or insane? Only in the movie, however. The case it was based on is [[http://en.wikipedia.org/wiki/Anneliese_Michel much less ambiguous, and far more depressing.]]
* ''Film/TheFactsInTheCaseOfMisterHollow'' has as its subject a {{Spooky Photograph|s}} of a SecretCircleOfSecrets, as observed by an OccultDetective looking for evidence. Over the course of the film, it's left rather ambiguous as to whether the elements of the photo that visibly ''[[CreepyChangingPainting change]]'' or manifest detail beyond what the eye could see are symbolic of the investigator's gradual epiphany as they [[PhotosLie tie events together]] and notice new details, a GlamourFailure on the part of the paranormal cultists, indicators of a potentially lethal PortalPicture, or some combination of all three.
%%* In the horror anthology, ''German Angst,'' the film "Make A Wish" [[spoiler:has a talisman said to be magic, but probably isn't.]]
* In the Don Knotts classic ''Film/TheGhostAndMrChicken,'' the invisible piano player who haunts the mansion is later revealed to be a parlor trick by [[spoiler:the Gardener, who is organizing a plan to unveil the murderer who killed the house's owners - their son.]] However, certain other things in the house are more difficult to explain, such as the front door, and at the very ending, when the protagonist and his love interest are being wed, someone starts to play the Piano in the tune of the ghostly theme - someone who isn't there . . .
* Cassandra Nightingale in ''Series/HallmarkHallOfFame'''s ''The Good Witch'' and its sequels. Usually, it's made clear that her "magic" is really [[{{Literature/Discworld}} Granny Weatherwax]]-style "[[SocialEngineering headology]]" ...but each film has at least one or two little moments (e.g., brooms appearing just when she needs to sweep up, doors opening of their own accord, plants in her garden seeming to shift to trip up trespassers, Cassie being able to greet someone by name before seeing them, Cassie being able to detect someone in pain while being on the other side of the house, etc.) that hint that she could have real powers.
* ''Film/{{Halloween 1978}}'' makes it ambiguous whether Michael Myers is just a really tough serial killer or whether he is, in fact, an indestructible Boogeyman. The film allows for either interpretation, though the last scene leans towards the latter. The sequels avert this by making Michael an explicitly supernatural entity.
* [[spoiler:Lillith]] of ''Film/HanselAndGretel2013'' claims to be hundreds of years old, and repeatedly makes characters hallucinate. However, there's no real proof to her claim of longevity other than a few photographs she claims depict her, and all of her tricks seem to be done via drugs.
* ''Film/HotTubTimeMachine'' repeatedly draws attention to this trope and straddles a strange line between playing it straight and parodying it in the character of the Hot Tub repair man, who may just be a {{cloudcuckoolander}} repair man, or may be some sort of TimePolice setting the time travelers on their way. Jacob even lampshades it, by noting that the repairman's words perfectly support either theory, and asks if it would kill the repairman to just give him a straight answer.
* The opening of ''Film/IndianaJonesAndTheTempleOfDoom'': Shiva sent you! Indiana attempts to convince them that it really was a string of wild coincidences that brought him there, alive, despite many, many things that could have killed him if they had shifted by a hair's breadth. Oddly enough, they continue to find the divine intervention plausible. (Later events are clearly supernatural; it's only Indiana's presence that is ambiguous.)
* It's possible "La Femme" from ''Film/{{Inside}}'' is some kind of ghost.
* The titular highway of ''Film/{{Interstate 60}}''. When Neal asks how he can be driving down a highway that doesn't exist, he's literally offered several possibilities.
-->'''Grant:''' Maybe it's another dimension, maybe you're in a coma, maybe you're hallucinating, or maybe, just maybe, you're dead.
-->'''Neal:''' So, which is it?
-->'''Grant:''' What do you want from me, kid? I just gave you a bunch of answers, all of them reasonable. You want an answer? Pick one!
* Fantastically done in ''Film/KPax'', where the film never truly answers the question of whether the main character, prot, is an alien or just a very convincing delusional man [[spoiler:named Robert Porter who suffered a psychotic break after his family's murder]]. The audience is left to wonder, and the possible consequences of either answer end up surprisingly heartwarming. Though the fact that he can apparently see infrared light makes the delusion pretty convincing.
* Film/{{Kundun}} takes this stance towards Buddhist beliefs about Reincarnation. It's never made clear if the Dalai Lama reincarnates into a young boy, or a young boy seems to be just the right kind of candidate who could be raised into becoming the Dalai Lama. The film's final lines hangs a {{Lampshade}}:
--> '''Indian Soldier''': "May I ask, are you the Lord Buddha?"
--> '''The Dalai Lama''': "I think that I am a reflection, like the moon on water. When you see me, and I try to be a good man, you see yourself."
* ''Film/TheLoneRanger'':
** The Lone Ranger somehow [[ItWasHisSled survives the attack on his team]]. The horse tells [[SpeaksFluentAnimal Tonto]] that the Ranger died and came back to life. Tonto tries to convince the 'spirit horse' to bring his brother back instead.
** Tonto also believes Cavendish isn't an ordinary criminal, but a Wendigo. This is the explanation for why the Lone Ranger uses silver bullets. Cavendish being a cannibal doesn't help things...
** The Lone Ranger not only gets a psychic vision from picking up a piece of Cavendish's silver, but despite not having fired a gun in ''eight years'' prior to his "death", he manages to repeatedly pull off ridiculous trick shots. He finally just goes with it.
--->'''The Lone Ranger''': ''"Spirit-walker." ...'''I can do this.''' ''([[spoiler:[[BlastingItOutOfTheirHands Shoots gun out of Cole's hand]] with his [[OneBulletLeft last bullet]] - [[CrowningMomentOfAwesome saving Tonto]] with [[ChekhovsGun the bullet Tonto forged to kill the "Wendigo"]]]].)
** And that crazy, crazy horse.
** This also falls under UnreliableNarrator thanks to the framing device of Tonto telling the story.
* In ''Film/MadMaxFuryRoad'', Max's flashbacks to Glory the Child seem like simple traumatised hallucinations, but the one that inspires him to [[spoiler: suggest that Furiosa and the wives take the Citadel]] contains a split-second precognitive vision of the [[EliteMook extremely tenacious Polecat]] who will later come ''very'' close to giving him a fatal headshot during the climax. The fact that the same vision reappears at ''precisely'' the right moment to help him survive said headshot (by triggering his instinct to cover his face just as the crossbow gets fired at his head,) might suggest there is something supernatural to it. If it is indeed Glory's ghost, then him receiving painful and distracting visions when he flees despite them telling him to "stop running", but helpful ones when he decides to help people, might suggest it is a benevolent ghost trying to guide him to reconnect with his fellow humans.
* In ''Film/AMatterOfLifeAndDeath'': did his head injuries cause his visions? Or are the angels really discussing the proper thing to do with him?
* ''Film/TheMenWhoStareAtGoats'': The film never answers if there's real psychic powers or not. [[spoiler:The main character does run through a wall at the end. However, a second after he's shown doing so, a picture frame falls off the wall, implying that he could have actually slammed into it but imagined himself going through.]] Like every other "paranormal" incident in the movie, it's up to the viewer to decide.
* ''Film/{{Mermaid}}'': It's left ambiguous whether Alice actually causes things to happen by wishing for them.
* In ''Film/MiracleOnThirtyFourthStreet'', the old guy who claims to be Santa Claus never does anything unambiguously supernatural. Even his ''piece de resistance'', finding exactly the thing Susan wants for Christmas even though nobody was sure it existed, ''might'' just be a stroke of good luck.
%%* Done ineffectually by the infamous finale of the B-Movie ''Film/MonsterAGoGo''.
* Depending on how you interpret [[spoiler: the eye protecting "true magic"]] in ''Film/NowYouSeeMe''.
* ''Film/{{Nymphomaniac}}'': Joe is possessed by The Whore Of Babylon (but maybe it was only an epileptic seizure after all). She later grows to lead a gang to fight against Love, because love only leads to jealousy... (or maybe this gang was an actual Satanic Cult after all). Having personally encountered demonic forces and been deeply involved with them, Joe has grown into an atheist who do not believe that the supernatural exist... but does this make her a FlatEarthAtheist or someone who has OutgrownSuchSillySuperstitions by acknowledging her own mental illness?
* ''Film/PansLabyrinth'' has two different audience interpretations according to whether the fairy world is real, or made by Ofelia's imagination. Creator/GuillermoDelToro says that he deliberately leaves at least one thing in his movies that can only be explained through supernatural means. In ''Pan's Labyrinth'', it's Ofelia using the magic chalk to get in the Captain's room and retrieve her brother. In ''Film/TheDevilsBackbone'', it's the [[spoiler: teacher's]] ghost freeing the children from the room they have been locked in.
* ''Film/ThePrincessBride'': [[MasterSwordsman Inigo]] and Fezzik are looking for someone with no time to lose. Inigo invokes his father's spirit and attempts to use his CoolSword like a dowsing rod. He runs into a tree, [[spoiler:but the knot he accidentally prodded is the switch that opens the secret entrance leading to precisely who they're searching for.]]
* Father Jonas in ''Film/PromNightIVDeliverUsFromEvil'' is either psychotic or possessed (or something).
* Vincent and Jules being miraculously saved from several gunshots at point-blank range in ''Film/PulpFiction''. Jules is convinced it's a miracle, while Vincent recounts hearing a similar story.
--> '''Marvin:''' ''Man, I don't even have an opinion.''
* ''Film/RealSteel'' leaves it up in the air if the robot Atom has a level of sentience, or is merely acting on its Shadow Function(that makes it mimic what it sees). The Commentary explains that there would have been a scene showing that it was indeed sentient, but it was later cut out to leave the question up in the air.
* At the end of ''Film/SalvationBoulevard'', Carl is walking away from [[spoiler: Pastor Dan's stabbed body]] when a bolt of lightning strikes [[spoiler:right behind him and he reveals that it severed the handcuffs behind his back without harming him]].
* This is the whole point of ''Film/ASeriousMan'', which is extremely stubborn when it comes to answering Larry's questions (and ours) as to whether the hand of God is at work in his life, or if there is a purely rational explanation for everything (as he wants to think).
* Wonderfully played in the climactic final confrontation between Holmes and Lord Blackwood in the 2009 ''Film/SherlockHolmes'' starring Robert Downey Junior, where [[spoiler: after dissecting every one of Blackwood's "magic tricks" as fakery, he comments that if Blackwood actually believed in his own sorcerous rites and the dark things he'd invoked, then he'd know what waited for him after death. Cue Blackwood accidentally falling to a hanging death, just as a crow flies past.]]
* In ''Film/TheShining'' film adaptation, it is unclear whether [[HellHotel The Overlook Hotel]] is haunted or not. Kubrick wanted to suggest that the characters seeing ghosts and other terrors might have been caused by cabin fever and things like Jack being let out of the food supply closet was just because of a badly locked door opening at the right moment. There are still elements that can only be explained supernaturally, such as Danny using his clairvoyance to warn Halloran and a ghost later telling Jack about this, or Jack appearing in a framed photograph in the Overlook lobby dating back to 1921.
* ''Film/TheSkeptic'' has Beckett seeing his mother's ghost throughout the film while staying in his aunt's house. He has severe repressed memories from when he was five and suffers from insomnia. He may be hallucinating his mother's ghost or she may exist. He's the only person who ever sees her, but the psychic is able to come up with a surprising amount of detail.
* Many a SlasherMovie will ask whether a character murdered, [[AccidentalMurder accidentally]] or otherwise, at the start of the show has come back for revenge à la ''Film/TheCrow'', or if it's just someone [[JackTheRipoff imitating]] (or [[RoaringRampageOfRevenge avenging]]) them; e.g. ''Film/SororityRow'' or ''Film/MyBloodyValentine''.
* In ''Film/{{Stalker}}'', it's never made clear how much power, if any, the Zone actually has.
* ''Franchise/StarWars'': In ''Film/RogueOne'' [[BlindWeaponmaster Chirrut]] has a religious belief in the Force but does not have Jedi training. Despite this it seems possible the Force truly is guiding him as he [[StrollingThroughTheChaos calmly walks through a firefight and is never even grazed]].
* In ''Film/DasTestamentDesDoktorMabuse'', it is left deliberately unclear whether the imprisoned and dying DiabolicalMastermind Dr. Mabuse managed to use evil psionic powers to [[GrandTheftMe take over the body]] of his psychiatrist Dr. Baum, or whether Baum went insane and developed [[NapoleonDelusion the delusion]] of being his former patient.
* In ''Literature/TheIliad'', Achilles' mother is a sea goddess. In ''Film/{{Troy}}'', she's a woman of questionable sanity who ''believes'' she's a river goddess. We're never quite sure whether she really is a goddess or not.
* ''Film/TheWailing'' strongly hinges on the "magic" side, but it is still perfectly possible to interpret the supernatural elements of the movie as toxic mushrooms-induced hallucinations and madness.
* In the 2000 movie ''Film/WakingTheDead'', Fielding's girlfriend Sarah is killed in a car bombing, but he keeps seeing her in crowds and hearing her voice. She eventually comes to his office late at night to say goodbye and Fielding doesn't see her again afterwards. Either she was a ghost, she faked her death and went into hiding, or Fielding's grief made him mentally unbalanced. None of these scenarios are proved or disproved.
* Werewolf horror film ''Wer'' does this in-universe. The first part of the film suggests that 'werewolfism' is a combination of a unique strain of porphyria (which, among other things, causes excessive hair growth and water retention) and the moon acting on the excessive water retention (in the same way it affects the tides) causes something akin to a psychomotor epileptic seizure in the disease-sufferers, causing them to go into blackout fugue-rages where a body's natural 'restraints' are turned off, resulting in seemingly superhuman strength and savagery. [[spoiler: Then the 'werewolf', his condition triggered by flashing lights, is shown to literally have his body WARPING under the skin...at which point he survives a multi-story fall without any injury, is shot numerous times and either ignores it or recovers impossibly fast, and is able to run on all fours at speeds that let him ''OUTRUN A CAR.'' So while he doesn't actually turn into a wolf man...]]
* In ''Film/TheWitch'', the titular witch's misdeeds ultimately amount to a handful of murders that could have been carried out without magic. And considering the circumstances, they easily could have been committed by [[spoiler: Thomasin, the family's eldest daughter]]. Note that the witch also [[spoiler: isn't seen or heard again after Thomasin ends up as [[FinalGirl the last character alive]]]], possibly hinting that [[spoiler:she was the witch all along]] and the witch's appearances were [[spoiler:[[ThroughTheEyesOfMadness hallucinations seen from her perspective]]]].

* In ''Literature/AfternoonOfTheElves'', do elves really live in Sara-Kate's backyard? Or is it all an elaborate game she's come up with, to impress the neighbor girl and add a little magic to her unhappy daily life? [[spoiler:Unusually for a book in this genre, after a twist that seems to imply the latter answer, the question is actually left unanswered to the very end.]]
* In ''Literature/AlienInASmallTown,'' when Nuada is about to kill Paul and Indira, Paul prays desperately to God to at least save Indira's life. An attack by a predatory alien animal then ends up indirectly saving Paul and Indira's lives. While it's perfectly plausible that it was the noise of their activities that attracted it, the timing of its arrival could easily have been an answered prayer.
* ''Literature/AlongTheWindingRoad'' has quite a few things that Arthur interprets as magical that may or may not be. [[spoiler: It's implied that most are magical, but never truly confirmed. Even when Arthur tries to prove he summoned the zombies, Charlotte nullifies the results by forcing antidote onto him.]]
* Literature/AmeliaPeabody often dreams of her old friend Abdullah, after he is killed. Only he looks young now, and he was old when they met... He offers promptings, rather than clues, about the mystery of the moment ... mostly. She comes to believe she's really meeting her old friend in the afterlife. Her family are not so sure, though their skepticism is showing signs of erosion by the end of the series.
* In Jo Walton's ''Literature/AmongOthers'', the main character is able to see supernatural beings and work magic. However, it is somewhat ambiguous as to whether the beings she sees are magical or the product of a lonely teenager's imagination, at least in the beginning of the book. The magic in this book mostly works in a subtle manner through coincidences that leave plenty of room for doubt as to whether the results were really due to magic after all. For example, the character tries to cast a spell to find some TrueCompanions because she can't find anyone at school she can relate to. The next day she gets just the kind of result she was hoping for when a librarian mentions a local science fiction book club and asks the protagonist if she'd like to join. The protagonist herself wonders whether this was a result of magic or coincidence as the book club had existed for a while before she'd ever heard of it.
* The horror novel ''Literature/ArielBlock'' contains a number of ambiguously supernatural elements. Several of the characters come to believe that Ariel's house is haunted, but it is unclear whether this is true or whether the belief is a part of their neuroses and mental breakdowns.
* ''Literature/TheBabySittersClub'':
** An early book, ''The Ghost at Dawn's House'', ends with [[spoiler: Nicky Pike]] being responsible for most of the strange things that Dawn observed--but not all of them. The ending of the book leaves open the possibility that Dawn's house really is haunted.
** Another example would be ''Mary Anne's Bad Luck Mystery''.
** Also, the first book in the Little Sister series, where the only undebunked evidence Karen has at the end is that she saw the lady she thinks is a witch flying on a broom... and that might have been a dream. A later book in the series had Karen suspect that Mrs. Porter's granddaughter, Drusilla, is also a witch. Drusilla later admits she's not, but says she's never been sure about her grandmother ...
* Every single Literature/BaileySchoolKids book is like this. Is the authority figure supernatural/villainous, or are the kids just jumping to conclusions?
* [[spoiler:Édouard de Gex's resurrection]] in Creator/NealStephenson's ''Literature/TheBaroqueCycle''. Was he [[spoiler:OnlyMostlyDead]], or did he genuinely [[spoiler:come BackFromTheDead]]?
* Richard Matheson's novel ''Bid Time Return'', the basis for the movie ''Film/SomewhereInTime'', is about a man who uses self-hypnosis to travel to the turn of the 20th century, where he has a romantic adventure. The problem is that we know from the start that he's suffering from a brain tumor, making him an UnreliableNarrator, and the novel ultimately raises the possibility that his whole time-traveling experience might be a series of hallucinations. The movie eliminates the subplot about his having a brain tumor and doesn't include anything overtly shedding doubt on his experiences. Nevertheless, in his review of the film Roger Ebert commented, "The movie never makes it clear whether the playwright actually does travel through time, or only hypnotizes himself into thinking he does."[[http://www.rogerebert.com/reviews/somewhere-in-time-1980]]
* In Creator/LMMontgomery's ''Literature/TheBlueCastle'', Valency offended her mother, who sulked. Then she got the letter from the doctor, which diagnosed her with a fatal illness. She thought the matter providential, because otherwise her mother would have asked whether there were any letters and read it; now she could keep it a secret.
* Set in a post-technological world, Creator/GeneWolfe's ''Literature/TheBookoftheNewSun'' challenges readers to think about whether events are mundane, magical, theological or technological in nature. For example: the Claw of the Conciliator: miracle-working religious relic, magic feather, alien device?
* In ''Literature/TheBrothersKaramazov'', Ivan's famous dialogue with the Devil might be pure feverish delirium, or might be a genuine vision. You're the reader: you decide. This is foreshadowed by his own parable of the Grand Inquisitor, when Alyosha ([[ArbitrarySkepticism tellingly]]) protests that the prisoner could not have ''actually'' been Jesus, and Ivan just says it doesn't matter either way.
* Each part of Walter M. Miller, Jr.'s ''Literature/ACanticleForLeibowitz'' (which take place hundreds of years apart) features a very similar old Jewish man. The WanderingJew -- or not?
* The ''[[Literature/TheCatWho Cat Who...]]'' books do this with the powers of the eponymous cat, Koko. Does Koko somehow know when someone close to Qwill is in danger and able to psychically intuit who the murder is? Or is Qwill just mistaking ordinary cat behaviour for mystical powers? In favor of the "magic" theory is the fact that Koko has done this so many times over the course of the series (him yowling once at the exact moment someone from Moose County is killed may be coincidence, him doing it a dozen times seems unlikely). In favor of "mundane" is the fact that the characters rarely manage to predict anything from Koko's clues, and the cat's "brilliance" is mostly revealed after the fact when the killer has been unveiled by other means.
** A lesser example in the same series is Mildred Hanstable's Tarot readings. They are vague enough that there's no proof Mildred can predict the future but almost always prove accurate.
* ''Literature/AChristmasCarol'' leaves it ambiguous as to whether Scrooge's visit from the three spirits was real or simply an elaborate hallucination.
* In Creator/RobertEHoward's Literature/ConanTheBarbarian story "Literature/BlackColossus" when Yasmela consults an oracle, being desperate, she does what it says despite this.
-->''"Mitra has spoken," replied the princess. "It might have been the voice of the god, or a trick of a priest. No matter. I will go!"''
** In "Literature/ShadowsInTheMoonlight", Olivia's initial conviction that statues in a certain hall came to life settled down to the view that it was this trope when she had to rescue Conan from {{Pirate}}s there. (The statues turns out to be RealAfterAll, but her awareness before it happened is not thus explained.)
-->''Was it some trick of the moonlight that touched the eyes of the black figures with fire, so that they glimmered redly in the shadows?''
* In ''Literature/AConnecticutYankeeInKingArthursCourt'', all of Merlin's "magic" relies on fakery and a gullible audience, and he's strongly implied to have no actual powers at all. [[spoiler: But at the very end, he casts a spell that really works, and it's never stated if he found some scientific way of pulling it off or if he really did have some magical powers after all.]]
* This is firmly in play in the ''Crimebiters'' series of novels for young readers in which the protagonist has a dog named Abby who is most active at night, seems to have fangs and which he claims is a "vampire dog," though none of his friends believe it. The books themselves don't really make it clear either way and the protagonist eventually comes to accept that it's probably best if his dog has a secret identity anyway.
* In ''Literature/{{Cryptonomicon}}'', also by Neal Stephenson, Enoch Root does something to [[spoiler:fix Amy's leg after she gets shot with an arrow.]] Neither of them are willing to say what he actually did. Enoch himself also qualifies for this trope, as he appears in both ''Literature/{{Cryptonomicon}}'' (set in WWII and the modern day), and in ''Literature/TheBaroqueCycle''. It's never explicitly stated if it's the same Enoch, or two men with the same name.
* In Creator/PoulAnderson's ''The Devil's Game'', what exactly is the title "devil"?
* Creator/SamuelRDelany's ''Literature/{{Dhalgren}}'': all sorts of strange things happen, ranging from mildly unsettling (several characters get exactly the same scratch on the thigh), through the absurd (the city's geography seems to rearrange itself), to the absolutely terrifying (the sun rises one day and takes up half the sky, and then the next day everything is back to "normal"). None of this is ever explained, so it could be the UnreliableNarrator, or it could be [[MindScrew something far weirder]].
* A more meta issue in ''Literature/TheDinosaurLords''. One one hand, the way the Grey Angels, Aphrodite's magic and Karyl's double resurrection is handled implies that there's magic on Paradise. On the other hand, there are just as many clues that Paradise is a human colony that regressed technologically after having advanced past the point of ClarkesThirdLaw being fulfilled.
* The final Franchise/DocSavage novel, ''Up From Earth's Center'' involves a trek through strange caverns which might be Hell. Though they try to rationally explain it as shared hallucinations caused by exposure to gas, they don't seem to be 100% convinced.
* This ambiguity is at the heart of Thomas Mann's ''Literature/DoctorFaustus'':
** Did Adrian Leverkühn [[spoiler:sell his soul to the Devil for 24 years of musical genius]]?
** Did he [[spoiler:contract a case of syphilis that drove him mad and killed him, but not before unlocking surprising sources of creativity in his brain]]?
** Are there any [[TakeThat parallels with Mann's home country of Germany and its "deal" with the Nazi party]]?
::Mann's apparent catch-all answer ... "Yes."
* In ''Literature/TheDresdenFiles'', Harry's ChurchMilitant friend Michael frequently receives very beneficial "coincidences." At least, Harry believes it to be coincidence. Michael is quite certain it isn't. Harry's repeatedly stated position is one of absolute neutrality -- as he describes it, Theological Switzerland. He acknowledges that Michael possesses a power unlike Harry's wizardry, but debates just how powerful Michael's divine protection and ability seem to be at times.
** In ''Grave Peril'', Father Forthill ''just happens'' to knock on his door at the same moment Michael needs to leave his house, because Forthill's car ''just happens'' to have gotten a flat tire nearby, freeing Michael to leave his younger kids with someone he trusts.
*** Also in ''Literature/GravePeril'', there is a woman who claims to have Cassandra's Tears -- the ability to foresee the future, but the inability to convince anyone of such. So, of course, Harry is left wondering if she actually has psychic powers or if there are other, more mundane reasons for her to know what she knows.
** At a few points in the books, Harry debates this to Sanya, one of the other Knights -- who paradoxically, is a confirmed agnostic -- and Harry's taking ''the side of Christianity''.
** In ''Death Masks'' Michael, wearing heavy armor and unconscious, and Harry are in a river when [[spoiler:crime lord Marcone]] tosses Harry a line and pulls both of them to safety. [[spoiler:The line turned out to be the ShroudOfTurin, though not the true shroud.]]
** In ''Proven Guilty'', Michael is mysteriously absent during [[spoiler: Molly's prosecution for the use of Black magic]], Harry's plan [[spoiler: to prevent her execution]] relies on Michael having been sent to just the right place for "coincidence" to work in his favor. [[spoiler:Michael did indeed as he saved three of the more lenient Senior Council members, Captain of the Wardens, and her training recruits from certain death. Arriving at the trial in time to take back their proxy votes from the more hardline leader]].
-->'''Michael:''' So what you're saying is, you took a leap of faith?\\
'''Harry:''' No, I took ''your'' leap of faith, by proxy.
** In ''Small Favor'', a civilian under attack by a monster is praying to God. [[BigDamnHeroes Cue Michael.]]
** Another time: In Harry's darkest moment in ''Changes'', Sanya manages to show up again just after an old woman screams "Oh, God in Heaven, help us!" Sanya claims it was probably just a coincidence.
* Pretty much every one of Terry Pratchett's Literature/{{Discworld}} novels dealing with the witches positively dances on this line. Witches obviously use magic. They also use "headology", which is essentially making people ''think'' they're using magic. Which one they're using at any given time isn't always clear. And then Granny Weatherwax gets annoyed at people's gullibility for assuming she's doing high-level magic when there's actually a perfectly mundane explanation, even though she and the reader know she ''was'' using magic and the mundane explanation is wrong. ("That's not the point. I might not have been.")
** Near the end of ''Discworld/MakingMoney'', Moist is in a jam, and decides to try praying to Anoia, [[OddJobGods Goddess of Things Stuck In Drawers]]. Later in the book, after he is saved from a mugger when [[spoiler:the man's dentures explode -- albeit after years of abuse]], he decides to make a thanks-giving offering of a ''really big ladle''. It's given extra weight by the fact that Anoia both really exists and owes him a big favor from his last book.
* In ''Literature/DragonFall'', Gabe is seemingly attacked by the three dragon dolls he created. They might be hallucinations as a result of the head injury he sustained during the rock concert, but they also seem to have done damage to the house that Gabe could not have easily replicated. The book ends before the question is resolved.
* Creator/EdwardEager's books are usually about children who find some kind of magic object and have adventures, but in two of them -- ''Magic or Not?'' and ''The Well-Wishers'' -- the main characters never find out if the wishing well was really magic or if everything that happened was just coincidence.
* ''Literature/EgilsSaga'': The same year after Egil has cursed King Eirik and Queen Gunnhild of Norway to be driven from the land by the land spirits, Eirik's rule is challenged by his brother Hakon, and by next spring Eirik and Gunnhild are forced to flee Norway.
* In the book version of ''Literature/TheExorcist'', the viewpoint character is able to come up with a mundane explanation for all of the goings-on. Some of them are more than a bit of a stretch, but it COULD all be explained rationally. In the film adaptation, on the other hand, it's pretty tough to explain away the levitating bed....
* In Joe Haldeman's short story, "The Monster," the narrator, Chink, a Vietnam vet, calmly and sanely relates his story of being a LURP in 'Nam and watching a glossy black humanoid creature tear apart his patrol-mates. But Chink is telling the story (presumably) to a psychiatrist in a mental institution, as an explanation as to why he slowly and brutally murdered an emigrant from Vietnam -- the man he believed to be the monster. At the end of the story, [[spoiler: we read a coroner's report that details Chink's death, allegedly from ripping out his own heart with his bare hands.]] We're never quite sure whether the titular "monster" was real, or just a figment of Chink's imagination....[[spoiler: or whether Chink killed himself, or the monster got him in the end.]]
* The "King's Cross" chapter in ''Literature/HarryPotterAndTheDeathlyHallows'': [[spoiler:Either Dumbledore [[DeadPersonConversation speaks to Harry from the afterlife]], or Harry is [[DreamingTheTruth sorting the information out himself]], using Dumbledore as a mouthpiece]].
-->'''Harry:''' Is this all real, or is it just happening in my head?
-->'''[[spoiler:Dumbledore]]:''' Of course it's all happening inside your head, Harry. But why on earth should that mean it's not real?
** Similarly, the Deathly Hallows themselves. They're definitely ''magic'', but are they "merely" high-quality creations of particularly talented wizards using the same "[[MagicAIsMagicA mundane]]" magic available to the protagonists, or are they [[WrongContextMagic mystical artifacts]] of [[TheGrimReaper Death himself]]?[[note]]Given that the InvisibilityCloak can be defeated by a common housecat, the Elder Wand is [[InformedAbility never shown to be undefeatable]], and the Resurrection Stone doesn't do anything that hundreds of animated portraits all over Hogwarts can't, likely the former.[[/note]]
** Also, Professor Trelawney is generally believed to be a fraud who enters the occasional genuinely prophetic trance, but almost every "fake" prophecy she makes comes true in some sort of way. Some of them can be explained as cold readings, but sometimes she comes suspiciously close to the truth - at one point she reads the cards in a way recognised by the reader (though not her) to identify that Harry's close by and in a bad mood; and at one point she gets Harry's birth month about as wrong as possible, but it's perfectly accurate for [[spoiler:Voldemort, a part of whose soul is sitting in Harry's head.]]
*** As well as Harry dying young (if only for a moment).
*** Though Trelawney makes just as many predictions that ''don't'' come true: classes are never canceled due to a flu epidemic and Neville isn't late to class on the second day.
* Marcus Pitcaithly's [[Literature/TheHerewardTrilogy Hereward Trilogy]] contains many, many examples of this trope. Are the apparitions at Frey's temple real or hallucinated? Does Brainbiter have real power, or is it just a CoolSword? Are the Toadmen's powers over animals real or not? Are the [[WillOTheWisp Will-o'-the-Wisps]] which guide the outlaws across the Fens a natural phenomenon or sent by St Peter? Is the Guardian of Wandlebury human? Does Gunnhild really have magical powers? And the unanswered question that runs right through the whole trilogy: is Lysir just a man, or is he actually Woden?
* Much of the fascination of Creator/ETAHoffmann stems from the mix of this with UnreliableNarrator and PurpleProse.
* Much of the premise of ''Literature/HouseOfLeaves'' is very heavily based on this trope.
* In Creator/AndreNorton's ''Literature/IceCrown'', Niles Ismay had an ancestor who slightly escaped Psychocrat conditioning and passed down stories. As a consequence, he, unlike most people on his planet, can understand Roane's story about the conditioning machinery. [[BecauseDestinySaysSo He thinks it must be destiny]]; she's less convinced, it's just chance.
* ''Literature/IClaudius'' is, for the most part, a straightforward and fairly realistic historical novel. However, there are a few suspiciously accurate prophecies regarding the fates of the emperors that are difficult to explain away as coincidence.
* ''Literature/JoePickett'': In ''Trophy Hunt'', Joe (and the reader) are left wondering if the bear that kills Eric Logue is just a rogue grizzly, or if it was some kind of spirit beast awakened to destroy a great evil (as Nate thinks it is). And there is still the mystery of who, or what, was performing the mutilations in the first place.
* In the Literature/JohnnyMaxwellTrilogy, the question of whether the [=ScreeWee=], the Dead and the time travel are all real or whether Johnny is, as Wobbler tactfully puts it, "mental", is resolutely unanswered [[spoiler: until the final scene of ''Johnny and the Bomb'', when Kirsty remembers it too]]. There is evidence supporting the former view, but it could all be explained away if you tried hard enough.
* Creator/StephenKing's "Jerusalem's Lot" is a ScrapbookStory told through a series of letters, diary entries, and other papers written in 1850. Our protagonist through this fantastic tale is Charles Boone, who writes his friend, nicknamed "Bones," about an EldritchAbomination, [[OurVampiresAreDifferent "nosferatu"]] and a TomeOfEldritchLore. The papers have been compiled by a present-day LongLostRelative of Boone's, who recites a few facts that seem to contradict Boone's narrative, and speculates that Boone was suffering from a recurrence of the brain fever which afflicted him after the death of his wife. Then we find out that the relative, James Robert Boone, has taken up residence at the very house where the 1850 events occurred, and has begun to hear the same stealthy sounds inside the walls which heralded the start of those events. Was Charles Boone insane, or are [[HereWeGoAgain things really beginning anew?]]
* ''Literature/LifeOfPi'' eventually sets up one of these: Pi tells the insurance company representatives two stories about his survival in the Pacific after a shipwreck, one involving sharing his lifeboat with a tiger and [[spoiler: a monstrous GardenOfEvil floating island made of algae and trees that eats people]] and the other just involving HumansAreTheRealMonsters. It's not clear which one is true, though Pi argues that the insurance reps should believe the former because it's a better story. [[spoiler: In the end, they do choose to believe that it was RealAfterAll.]]
* Encountered many times in ''Literature/TheLordOfTheRings'':
** When Frodo and Sam have climbed down the rope given to them by the elves, it comes free. Frodo says the knots must have given way, and Sam thinks that it came when he called it. Neither one thinks either explanation very good, but both conclude that it had to be that way because nothing else would have worked. Later, a third possibility is implied, when Gollum mentions burning his hands on elven rope but gives no details of when and where this happened. (In the film version it's explicitly magic, and both accept this instantly.)
** Other instances: Was Frodo divinely appointed to be ringbearer or was it blind luck? Did supernatural intervention block the pass of Caradhras or did they just get there in a bad season? When Frodo heard that voice on the steps of Amon Hen, was that God or Gandalf or just his own good sense kicking in? Etc.
** Invoked when some elves of Lothlórien reveal that what is magic and what is mundane is a question of perspective in Middle-Earth, as the elves themselves have no concept of "magic" -- a lot of things that are natural to the elves are considered magic by mortals, lumping it together with methods employed by Sauron, which the elves will never use.
-->'''For this is what your folk would call magic. I believe; though I do not understand clearly what they mean; and they seem also to use the same word of the deceits of the Enemy. But this, if you will, is the magic of Galadriel.''
** Tolkien's other works also feature this:
*** ''Literature/TheChildrenOfHurin'': Was Túrin's terrible life because of Morgoth's curse or because he doesn't know when to swallow his pride? Complicating this is the implication that if Turin had stayed in Doriath he would have remained safe.
*** ''Literature/TheSilmarillion'': Did the Sons of Fëanor ''really'' have no choice in pursuing their Oath, or are they only saying that to justify their horrific actions to themselves?
* In Creator/DorothyLSayers's Literature/LordPeterWimsey novels:
** In ''The Nine Tailors'', one of the bells is "known" to have killed two evil-doers in the past. At the end of the book, Lord Peter realizes [[spoiler:the victim was also killed by the bells, in this case by being in the belltower during a long peal,]] which may have been a third instance of the bells dealing out justice. (His arrival at the beginning was heralded as something that might be called chance.)
** In ''Murder Must Advertise'', Dian regards the Harlequin as a lucky charm because she wins twice at horses, and afterwards is good at cards. The narrator says this ''might'' be just her determination.
* In Jack Campbell's ''Literature/TheLostFleet'', Desjani (and a increasing number of [[HeroWorship fanatics]]) believe that Geary is [[TheChosenOne blessed]] by the spirits of their ancestors. On the one hand, Geary never shows any knowledge or insight beyond his impressive tactical skills; on the other, [[ForWantOfANail if not]] for a lot of small events [[note]]the fleet noticing his cryo-pod drift through space, the fleet being in that exact location to begin with, Geary being alone in his pod (allowing it to sustain him longer than usual), the fleet picking him up a few months before said pod was set to expire...[[/note]] happening in ''just'' the right way, Geary would have perished in cryostasis- and, with him, the titular lost fleet ''and'' the entire Alliance government.
** Geary himself prays for guidance at times and always comes away disappointed he never saw a sign or felt a message. But sometimes something small will happen that leads to an inspiration.
** In the spinoff series novel''Literature/TheLostStars'' novel ''Tarnished Knight'', Iceni considers the prospect of Drakon's failure at one or more ISS site. This will give her the choice of letting ISS endanger her and bombarding from orbit, causing grave harm to many civilians in the area. Despite not believing, she prays to the living stars for guidance. Almost immediately, the displays light up with his success. She tries to convince herself that it's a coincidence, but wrestles with it -- and there's, of course, no evidence either way.
* In Creator/AgathaChristie's ''Literature/TheMysteriousMrQuin'', Mr. Quin has a knack for the StealthHiBye, of showing up just when something is about to happen, and of saying or doing just the right thing at just the right moment to nudge events in the direction of a happy conclusion. It's heavily implied that he's something other than human, but he never does anything unambiguously supernatural.
* In Marisha Pessl's ''Literature/NightFilm'', A journalist investigates the suicide of the daughter of a cult horror film director and soon learns that the family was involved in black magic. He begins to believe that the dead woman is cursed, until learning that she actually had cancer. Everything that happens can technically be explained rationally, although we are left to wonder.
* In Creator/JohnHemry's Literature/PaulSinclair novels ''A Just Determination'' and ''Burden of Proof'', after the death of men, the crew believe that the ghosts are haunting them. When two junior officers are in free fall, a screw starts to move. The engineer explains that vibrations could cause that.
* ''Literature/{{Pharaoh}}'' is full of weird incidents. Some can be explained by people hiding in the dark (Pentuer confesses to having dispensed advice that way) but some are plain weird (Kama falling ill - was it a {{Curse}} for breaking her vows? Or was it purely [[FreakOut psychosomatic]]?
* In ''Literature/PleaseDontTellMyParentsImASupervillain'', Penny's dad maintains that magic is just SufficientlyAdvancedTechnology, others aren't so sure, and it's never established one way or the other. For her part Penny's just fine with calling it magic even if it is just another form of technology.
* In L. Jagi Lamplighter's ''[[Literature/ProsperosDaughter Prospero Regained]]'', Gregory recounts a vision that changed him -- and then immediately dismisses it as a delirum, albeit one that made him think.
* In Brian Jacques's ''Literature/{{Redwall}}'', Matthias [[TalkingToTheDead addresses a tapestry showing Martin the Warrior]] about his weakness.
* A minor one in the ''Literature/{{Relativity}}'' story "The Legend of the Cheese Maidens": The legend itself at first appears to be something Ravenswood made up, but at the end of the story it's revealed that everyone in his home town knows it. Whether the events in the legend actually took place or not is never clarified.
* Barbara Roden's story "The Things That Shall Come Upon Them" is a crossover featuring Franchise/SherlockHolmes (a rationalist skeptic) and Flaxman Low (an OccultDetective from stories by Hesketh Hesketh-Pritchard) who are both trying to solve the case of an apparently haunted room. Holmes comes to the conclusion that the phenomena were caused by someone sneaking in from the outside through the discovered secret passage, while Low believes that the room is inhabited by a malevolent spectral entity. It's not made explicit which is the correct explanation, though it's subtly implied that Low was right, as there are several holes in Holmes's theory.
* In Sharon Shinn's ''[[Literature/{{Samaria}} The Alleluia Files]]'', the revelations about the spaceship do not shake all the characters' faith. Some still think that their lives, and these events, had been divinely guided. [[spoiler:Indeed, Tamar, raised to disbelieve, announced that she had come to believe.]]
* In K.J. Parker's ''Literature/TheScavengerTrilogy'', after he loses his memory, all of Poldarn's actions are consistent with being just a unwittingly malign man, mired in circumstance and human nature ''or'' being the [[spoiler: God of Destruction. Or possibly the human agent for a group mind of crows. Or both.]]
* In Kate Seredy's ''The Singing Tree'', the cat acts ill in the cart, so they stop by a hospital where they learn she's having kittens. They wait, and Kate and Lily help the nurse bring soup to the wounded. Which is how Kate [[spoiler:sees the amnesia case and realize it's her Uncle Marton -- shouting that at him jogs his memory lose. When arguing that they should take him home despite his lack of papers, one argument is that it was obviously Destiny and who are they to argue with destiny]].
* Many of Zilpha Keatley Snyder's novels ride on exactly that variation of the trope. It's especially noticeable in ''Literature/TheChangeling'' and ''The Witches of Worm''.
* Creator/GeneWolfe's ''Literature/SoldierOfTheMist'' and ''Soldier of Arete''. He, and those around him, think he's been cursed by the gods to forget everything every night. Even the gods speak of it when they talk to him. We, on the other hand, have enough evidence about his head injury to conclude that that may explain both the amnesia and the hallucinations.
* ''Literature/ASongOfIceAndFire'' appears to have a clear relationship between the existence of dragons and that of magic. The dragons died out before the start of the series, with only a few dormant eggs left behind, and no living dragons = very limited magic. So the series starts with little magic (although some of it seems rather powerful) and until Daenerys hatches her dragon eggs most "magic" is faked, lucky, or misunderstood. After Dany hatches the dragons, the lines get blurred; while more true magic is [[TheMagicComesBack beginning to occur]] and is increasing in frequency and power as the dragons grow and Daenerys gets closer to Westeros, there are still fakers and lucky people out there, as well as ignorant people who will claim that perfectly normal events were the result of magic. Some examples:
** The Red priests and the priests of the Iron islands have always had a "miraculous" technique of restoring life to the recently dead or drowned that is initially very clearly described as a variant of modern CPR and rescue breathing, making it entirely mundane... until, in book four, they begin using the same techniques to resuscitate people that haven't been breathing for hours or, in a few cases, DAYS.
*** There is one particularly confused Red priest who used to light his sword on fire with oil as a party trick, then one day accidentally tried it without the oil and found it worked anyhow.
** In ''A Storm of Swords'', Stannis and Melisandre perform a ritual which will supposedly cause the deaths of [[spoiler:the other three surviving kings, Balon Greyjoy, Robb Stark, and Joffrey Baratheon.]] By the end of the book, they're all dead... but they all died separately, from completely unrelated causes. More importantly, the events leading to the deaths were, in two and possibly all three cases, set into motion well before Stannis even performed the ritual. [[spoiler:Tywin Lannister had already plotted to kill Robb, Margaery and Olenna had been making provisions for Joffrey, and while the cause of Balon's death remains somewhat unclear there is a long, long list of people who might have been planning to take a shot at him - not least [[CainAndAbel Euron Greyjoy]], who conveniently appeared just after his death to claim the throne, and in a preview chapter of TWOW reveals he was responsible.]] To make things more confusing, Melisandre has ''definitely'' performed legitimate magic prior to the ritual, most notably sorcery that was definitely the cause of [[spoiler:Renly Baratheon]]'s death. According to ''A Dance with Dragons'' Melisandre's powers [[spoiler:are a combination of tricks and legitimate magical power, and even the magic is a mix of blood magic and legitimate divine power. Since the rebirth of the dragons, she's been using more of the latter kind.]] There are even theories Mel's ceremony was just to demonstrate the power of King's blood, [[spoiler:but she had already seen the rival King's deaths in her flames.]]
** Then there's the matter of Cersei, who was told by a witch that she would marry the king, that the king would have sixteen children and Cersei three, all of whom would wear golden crowns and die before her, and that she would be supplanted by a younger, more beautiful woman and choked to death by [[spoiler:her younger brother.]] The matter of the king's bastards has already come true, and two of her children have been crowned and one has died. There are many beautiful, younger women (Margaery, who married the usurper King Renly and then King Joffrey, then King Tommen, Sansa, who could yet become Queen in the North, and Daenerys, the last claimant of the old Targaryen dynasty across the sea who calls herself Queen and has dragons)that could destroy her. While Tyrion always had good cause to hate her, by the end of tha last published book she has been absolutely vile to ''both'' [[spoiler:her brothers (remember that Jaime is the younger twin by a matter of seconds,)]] so that now one ''really'' wants to kill her and will very likely make an attempt if there paths ever cross, and the other is estranged and it's not out-of-the-question that circumstances could conspire to set him against her too. Coincidence?
** PsychicDreamsForEveryone! Except that it's ''really really hard'' to tell the difference between a true psychic dream and a hallucination, especially since most psychic dreams occur while characters are badly injured/feverish/etc. (such as Bran's dreams of the three-eyed crow during his coma, or [[spoiler:Jaime]]'s visions regarding [[spoiler:Brienne]] during a traumatic injury and subsequent severe infection. While the former's visions seem to be genuine, the latter's might yet swing either way--though they seem to be mundane, as the character they were dreaming of might be ''dead''.)
*** The most borderline case of a possibly psychic dream? [[ManipulativeBastard Euron Greyjoy]] mentions that he dreamt a crow told him he could fly in a dream, which is similar to a dream another character had that turned out to have a magical origin.
** The supposedly "cursed" castle of Harrenhal. Most educated characters in the series dismiss the curse as nothing more than the superstition of ignorant peasants, and would themselves explain the "curse" as the fact that castle's sheer size makes holding it a logistical nightmare and a catastrophic drain on resources. However, in a world where most of the great strongholds have belonged to the same family literally since pre-history, nine different families have controlled Harrenhal in just three hundred years. Moreover, most of the characters who have been in Harrenhal since the series started have come to a bad end, even one who was named Lord of Harrenhal but never even got there and was dispossessed of it shortly after, died the following year. All-in-all, no matter how much people may dismiss the curse, they aren't exactly eager to claim the title "Lord of Harrenhal" either.
* ''Song of Kali'' by Creator/DanSimmons:
** The protagonist Robert Luzcak is in Calcutta looking to interview the poet M. Das, who was thought dead but has made a return. He's told a wild story about how a cult of Kali had brought Das back to life. When he finally manages to meet Das, the poet does look like a corpse -- because of an advanced state of leprosy. Das himself confirms the idea of leprosy but still claims to have died and been brought back to life. When Luzcak points out that the timing doesn't match that of the story he'd heard, Das says something vague about "re-enactments" (though the original story didn't involve any apparent intentional re-enactment so much as a randomly chosen dead body). Subsequently, Das apparently dies (again?), but Luzcak later gets a letter claiming him to be alive again, together with a photo featuring him -- which could just be an older one, of course.
** When Luzcak is captured by the cult, he finds himself in the darkness in their secret temple of Kali. He runs into the statue of Kali inside and hits his head. Soon after, he sees the statue moving and approaching him to attack. Throughout this experience, he burns the matches in his pocket and then the pages on his notebook to see in the darkness. The experience ends suddenly with the cultists rather than the statue grabbing him, as if he might have just hallucinated the whole thing after hitting his head. Subsequently, he finds that he has no matches left but has an untouched notebook -- but he thinks he ''might'' have had two notebooks with him to begin with.
* The ghosts in ''Literature/SonicTheHedgehogInCastleRobotnik'' are never confirmed one way or another. Sonic insists that they're just special affects but the author goes out of his way to say that they must be extremely good special effects.
-->''A huge white blob of supernatural (or perhaps special effect-ual!) force screamed out across the room, blew apart the ghost standing in the doorway...''
* In ''Literature/TheTenetsOfFutilism,'' Sasha goes through some pretty insane coincidences (randomly meeting her father's old war buddies on a trip, finding out the man she married is related to her father's lost love, etc). The unlikelihood of these events eventually leads her to believe they are supernatural in nature. Sasha, having previously been forced into a cult, attributes her luck to their god of fortune. The coincidences in the book ''are'' pretty unlikely. Then again, it's pretty obvious that she's crazy by the end, and there's no concrete evidence for her experiences being the result of divine intervention.
* In Creator/CSLewis's ''Literature/TillWeHaveFaces'', it's unclear whether certain events are caused by the wrath of the gods or whether it's just coincidence being misinterpreted by a superstitious people. [[spoiler:Until the narrator sees a god with her own eyes]].
* Henry James' ''Literature/TheTurnOfTheScrew'' is an early example: are the ghosts real or a figment of the governess's neurotic imagination?
* ''Literature/TheUnderlandChronicles'':
** [[spoiler:Ripred points out that Sandwich's prophecies may well just be coincidence or [[SelfFulfillingProphecy self-fulfilling]], and he doesn't believe in them. They seem to be pretty accurate, but only after a book of trying to decipher them and you can see how they could be reinterpreted to fit the latest explanation.]]
** Mrs. Cormaci, who tends to send just the right objects at just the right times and who gives tarot readings. Gregor at one point wonders if she can see what he needs in her tarot cards, and given that psychics exist in this series, he could be right.
* In Creator/GrahamMcNeill's TabletopGame/{{Warhammer 40000}} Literature/{{Ultramarines}} novel ''Black Sun Dead Sky'', when Uriel is trying to convince the Unfleshed of his friendliness, their icon of the Emperor lights up -- either a mechanism jogged by Uriel's movement, or a miracle.
** Earlier, Uriel had argued that a chance meeting had occurred BecauseDestinySaysSo.
** In ''Nightbringer'', the AlmostDeadGuy Gedrik should have been dead. Uriel takes what appear to be ramblings very seriously: he thinks that being so near death may have given him visions.
* In Creator/JamesSwallow's ''TabletopGame/{{Warhammer 40000}}'' Literature/BloodAngels novels:
** In ''Deus Encarmine'', Rafen remembers, in his BackStory, how he had once thought he had seen Sanguinius in lights in the sky; perhaps a trick of the mind, through fatigue and [[DespairEventHorizon despair]], but it reminded him that the Pure One was judging him and caused him to rally.
** In ''Deus Sanguinius'', when TalkingToTheDead, Rafen asked [[spoiler:Koris]] to guide him one last time. The dead man's communicator fell to his hand. It ''had'' been sheared loose, but fell only then. [[DueToTheDead Although using dead men's equipment was forbidden except under the gravest of circumstances]], Rafen takes it up and uses its command codes.
** Again in ''Deus Sanguinius'', after psychic attack by Inquisitor Stele has [[DrivenToSuicide driven him to suicidal depression]], Rafen flees. He stumbles on the mediation chamber he had made for himself earlier -- explicitly described through the guiding hand of the Emperor, muscle memory, or blind chance.
** In ''Black Tide'', Rafen wonders whether his capture was the guiding hand of the Emperor or capricious fate. (If it's the first, he will do his duty; if the second, [[ScrewDestiny to hell with fate]], he will do his duty.)
* In Creator/DanAbnett's Literature/GauntsGhosts novels, Larkin's scope. It appears to show him things. Except that he's several cards short of a full deck.
** His best example comes from the story of the Angel in ''Ghostmaker''. In a mission to sneak into a Chaos-held city and snipe its leader, Larkin loses it and abandons the mission team. He holes up in a room high up on a tower with a statue of an Imperial Angel - which he imagines talking to him, convincing him to do his duty and giving him a strip of cloth to help steady his aim. He ends up taking out the Chaos warlord, then passes out. When he comes to, other Ghosts are helping him up, and Angel is just a statue again - but his long-las is sitting in the corner with a band of silk tied to it. In the same book, looking through the scope makes him the only one to break free of an Eldar illusion; it isn't clear if the scope was responsible or not, since he already had enough doubt that he was intentionally using it to test his suspicions.
** There's also the... [[OneManArmy impressive]] performance of Saint Sabbat in ''Sabbat Martyr''. On the one hand, she has a small fortune worth of the best armor and weaponry the Imperium has to offer. On the other hand, she comes by the title "Saint" honestly. (On the gripping hand, she solo-kills ''a [[TankGoodness Baneblade]]'' and duels and kills a Chaos warlord.)
* In Bernard Cornwell's ''[[Literature/TheWarlordChronicles Warlord]]'' series the narrator maintains that all the magic shown by Merlin, Nimue and others have possible natural explanations but that they could also be genuine. Further confusing things is Nimue's admission that some of her and Merlin's magic is indeed just trickery while other parts are very real. During the course of three books the series plays with the existence of magic just about every way possible, whether it be that magic seems to be real, seems to be fake, or is left ambiguous. And sometimes a spell or magic artifact will appear to work powerful, genuine magic, only to completely fail to work at all later. Ultimately the first two books lean towards things being mostly, if not entirely "mundane", but the last one has several events that are really difficult to explain without magic.
** Bernard Cornwell really likes this trope, with Literature/TheSaxonStories pulling it every now and then, with the rune sticks being disturbingly accurate and Uhtred's shadow walker antics.
** Even possibly Sharpe providing an example with the Gonfalon of Santiago, though the last leans very much on the mundane end of the spectrum.
* In ''Literature/WarriorCats'', during a big battle over leadership in [=WindClan=], lightning strikes a tree, causing it to topple over and form a bridge to a nearby island (which would then be used as important neutral ground for the four Clans). It also crushed the cat attempting to usurp leadership. The cats (and some of the fans) see this as far too convenient to be coincidence, and believe that [=StarClan=] directed the lightning. On the other hand, the cats have seen [=StarClan's=] influence in things they had nothing to do with before, and [=StarClan=] have also stated that they have a strict non-interference policy.
** At least in the first series, it's arguable whether or not StarClan exists at all. Maybe Scourge really is so strong that he can drain a Clan Leader's 9 lives in a single kill...or maybe everyone only gets 1 life, and the only difference is that a Clan Leader is harder to kill because of his or her experience and talent.
* In Andy Hoare's Literature/WhiteScars novel ''Hunt for Voldorius'', Kor'sarro is not sure how he recognizes that Nullus is a daemon; intuition, or maybe being near another daemon.
* In Kate Seredy's ''The White Stag'' it is never clear if the forces that brought the Huns to the new land and the white stag are a higher being fulfilling prophecies, or just plain luck.
* Charles Brockden Brown's ''Wieland'' toes the edge of this trope. Though it is revealed that [[spoiler: the voices which Wieland hears have a physical source,]] the fate of Clara and Wieland's father is still ambiguous: [[spoiler: it was either the inexplicable wrath and majesty of God, or {{spontaneous combustion}}. [[ScienceMarchesOn Which people did believe in in those days!]] ]]
* Creator/JacquelineWilson did this in two of her early novels. In ''The Power of the Shade'', the heroine becomes obsessed with the idea of witchcraft after a friend introduces her to the concept, and slowly comes to believe that she really has magical powers. In ''The Other Side'', a girl suffering from severe personal trauma believes that she can astrally project. In both cases it's left open as to whether or not these powers are real.
* It is not always clear in ''Literature/WizardOfThePigeons'' whether an event is genuine magic or just misapprehension or coincidence.
* In ''[[Literature/{{Xanth}} Castle Roogna]]'', a ring claims to be magical, a wishing ring. When Dor makes a wish on it, it answers, "I'm working on it." Every wish made on it comes true through outside factors -- except that every wish made on it ''does'' come true, and it never claimed that it could pull off instantaneous wish granting.

* Murdock of the ''Series/TheATeam'' is either insane, or a very good actor. Though most of his ramblings (such as that golf balls need to breathe) are clearly not founded in reality, he is actually capable of seemingly becoming invisible to anyone who doesn't know him (either that or he paid off the waitress to play along). Also, at the end of one episode his imaginary dog Billy pulls him off-screen in a manner that couldn't be faked without something else actually pulling him.
-->'''Client:''' Is he really that crazy?
-->'''Hannibal Smith:''' We don't know...
* ''Series/AuctionKings'':
** The Ouija board, which predicts it's own sell price. It was appraised at between $100 and $200, and itself predicted the price would have a '5' in it. It ends up going for $150... the exact middle of the appraisal and a value with a '5' in it. Cindy is not amused when she realizes Jon bought it.
** The haunted art cabinet. The medium brought in claims it has positive energy. Another artist buys it to store art supplies. Hopefully, the ghost is satisfied.
* ''Series/BabylonFive'' usually went with [[SufficientlyAdvancedAliens First One technology]] for its 'supernatural' effects, but a couple of episodes are more ambiguous.
** Neil Gaiman's fifth season episode "Day Of The Dead" leaves it ambiguous whether the [[spoiler: dead people that came back for the night]] are a result of Brakiri telepathy or the genuine article. At the end, it seems to come down on the side of [[spoiler: the supernatural]].
** In ''Voices in the Dark: Over Here'' story of ''The Lost Tales'' follow-up has a man who claims to have been possessed by a demon on his shore leave on Earth. He is able to know intimate details about people, but since telepathy is a well-known phenomenon in the 'verse, it's not that surprising. He is also somehow able to get people to smell different things, although that could also be explained by some form of telepathy (i.e. they only think they're smelling it). Lochley definitely believes him, though, and makes sure that the exorcism takes place on Earth (if it had taken place in space, the demon would be free to roam the universe).
** In the first season episode, "Soul Hunter", the titular character and Minbari Ambassador Delenn believed he was capable of capturing the souls of the newly dead. The Soul Hunter believes souls are lost if uncaptured, while Minbari believe in reincarnation and capture prevents it, so there's conflict. Dr. Franklin suggests that it could be possible to copy a person's memory and personality as data, but doesn't believe corporeal technology could capture a soul. No conclusions are made. Soul Hunters reappear in the TV movie ''River of Souls'', where a group of tomb raiders breaks into a Soul Hunter shrine and take a large sphere that later turns out to be holding the souls of an entire race. At the end, though, it's revealed that they're not souls, they're EnergyBeings that have been taken by Soul Hunters at the moment of [[AscendToAHigherPlaneOfExistence ascension]].
* Several times in ''Series/BarneyMiller'', the detectives arrested someone who appeared to be unstable due to some outrageous claim they were making; however, due to the circumstances, you could you never be ''totally'' sure theses people weren't crazy. (And most were played by Kenneth Tigar.)
** Mr. Kopechne (the first one played by Tigar) was a prisoner who claimed to be a werewolf, and while his 'lycanthropy' is not taken seriously, his return as a victim of demonic possession is far more disturbing.
** The man who claims to be Jesus (also played by Tigar) returns and gains the friendship (and discipleship) of a suspect named Paul with a "miracle" akin to changing water to wine: a bag of drugs turning out to be a BeatBag, freeing him of charges. Paul had asked him for a miracle "like when you made all those sandwiches."
** A man (Tigar again) plagued by a poltergeist named Julius, concurrent with a lot of small accidents and an attack of clumsiness.
** A time traveller [[Series/DoctorWho in a long striped scarf]], who identifies himself as such because he's sure nobody will believe him, convinces Harris to invest in zinc, apparently recognizes ''the'' Arthur Dietrich, and vanishes after leaving.
** A "clairvoyant" who attacks a man for a purse-snatching he hasn't committed, but it just so happens he picked a repeat offender... and he perceives the cloud of "resentment" that results from Luger turning up, subsequently broadcasting Barney's frustrations.
** A rainmaker hired by New York City's department of water during a drought appears to be successful after being arrested for lighting a ceremonial fire in Central Park. (He insists he was doing it scientifically by stuffing the raw chicken with cloud-seeding chemicals.)
** A man who claims to be "a combustible" (as in, spontaneous) insists that he is overheating in the cell and needs ice just before the wastebasket across the room catches fire. Barney's response? "Get him some ice."
** A man who believes he is plagued by a succubus falls asleep in the cell, where he dreams very loudly and... vividly.
** An ''obeah'' woman at one point seemed to prevent Harris from opening the cell door by looking at it. Toward the end of the episode, she presented Barney (who at the time was reconciling with his semi-estranged wife) with a talisman.
-->'''Obeah:''' Just wave this talisman three times over your bed, and souls that were separated will soon be reunited.
-->''(Barney gives Wojo a DeathGlare)''
-->'''Wojo:''' I didn't say anything, Barn!
* The DarkerAndEdgier ''Series/{{Battlestar Galactica|2003}}'' showed characters with clear religious, atheistic and agnostic views. Much of the StoryArc dealt with whether the gods or God were directly leading the remnants of humanity to their new home, or whether coincidence was just a matter of their reality. By the series' final season, [[spoiler: the reappearance (and then sudden final disappearance) of an AngelUnaware]], as well as a final scene that showed two people, images of main characters that had haunted their counterparts throughout the series, [[spoiler: in the modern Earth, 150,000 years later,]] as fans questioned if the images were hallucinations or technological constructs. The show ended with a significant lean towards the supernatural.
* In ''Series/BlackJesus'', Jesus demonstrates various powers, such as turning water into cognac or destroying a lock with his bare hands, but it isn't clear whether he's actually Jesus or some kind of con man and/or crazy. The other characters are split on whether he's really Jesus.
* ''Series/{{Bones}}'':
** "The Man in the Morgue" takes place in [[TheBigEasy New Orleans]], and of course involves HollywoodVoodoo, and even some EasyAmnesia. Surprisingly, it plays the trope rather well - the viewer is left wondering if Bones is drugged or hexed.
** Another episode was a ''[[Film/TheBlairWitchProject Blair Witch Project]]'' homage. The ghost of the witch is revealed to be fake, until the end, when Angela and Hodgins discover the blurred outline of a woman in some video footage. It ''could'' be just moonlight...
** A mild example in "The X in the File" where we get a few alien scares only to turn out to have perfectly normal explanations. One of them even freaks out Brennan when a fossilized woman suddenly rises up during an MRI scan (she had some metal in her). The ending, though, creeps out many viewers using the NothingIsScarier trope: Brennan and Booth are only on a car hood in a remove field looking up at stars and discussing the possibility of the existence of alien life. Suddenly, all sounds stop, including the insects and the wind, and the characters look very disconcerted. SmashToBlack.
* In the ''Series/BoyMeetsWorld'' Halloween episode "The Witches of Pennbrook", Jack dates a girl who claims to be a witch, and later reveals she has evil intentions: she tries to use Jack as a sacrifice to gain immortality by placing him in the path of a light beam from the sky she claims has destructive powers, though her plans are thwarted by Eric. At the end it is left unclear if she was really a witch or just crazy and if the light beam was real or not. Eric actually says something similar to the trope name when discussing it.
-->'''Jack:''' Eric, I saw the light beam. Was that real?
-->'''Eric:''' Jack, maybe it was and maybe it wasn't. There are some things just too big for our puny heads to comprehend.
* ''Series/{{Buffy|the Vampire Slayer}}'':
** One memorable episode featured a demon that caused Buffy to [[CuckooNest hallucinate herself in a mental hospital]]. Her mother was still alive, her parents were still together, and she was diagnosed as paranoid and delusional. The episode never really explained if everything we've ever seen in the show is real, or all part of a sad girl's hallucinations. (Or ''both''. It's not the first time we've seen alternate universes on ''Buffy'': maybe there's one reality where everything we see happens, and another where Buffy hallucinates it all.)
** In the episode "Amends", a snowfall prevents Angel from killing himself. The chances of a blizzard in Southern California are incredibly small, but there's still a chance that it was entirely mundane. In the ''Series/{{Angel}}'' spinoff series it's further hinted at that the PowersThatBe may have intervened, but it's still left pretty ambiguous.
* ''Series/{{Castle}}'':
** The episode ''He's Dead, She's Dead'' has a murdered "psychic" who may have left behind a prediction of her own murder...or maybe it was left by the murderer to confuse the police. Castle wants to believe theory A, Beckett believes theory B. At the end the culprit is lawyered up and not telling. The victim's daughter, also a psychic, tells Beckett that someone with the name Alexander would be important. She finally tells Castle the woman mentioning Alexander to further her argument against psychics since nobody in the case had that name. Turns out, [[spoiler: Castle's birth name was Richard Alexander Rogers]]. She's left to wonder if she was wrong or if it was a coincidence.
** "Demons" is set in a supposedly HauntedHouse, with Castle again taking the role of [[AgentMulder believer]] and Beckett the role of [[AgentScully skeptic]]. Although there's ultimately a mundane explanation that plausibly explains the events of the episode, there's still one or two things that suggest the house could be haunted after all. There's also the ending, which has the elevator button light up and the door open ''before'' Castle can hit it...
** The physical hints we get of time travel in [[Recap/CastleS6E5TimeWillTell "Time Will Tell"]] can be explained by coincidence. But, and it's doubtful the writers realized this unless they actually ''were'' intending to turn the show into science fiction, what cannot be explained away is that the entire plot makes no sense at all if you assume the 'time travelers' are just delusional. [[spoiler: The behavior of the actual killer makes absolutely no sense if the killer is not a time traveler. The 'official' story, if he's not a time traveler, would be that he first tracked down the person he wanted to kill, then tracked down a letter that person sent and made a copy (how did he even know about this letter?), then tracking down someone who knew where the recipient of that letter was (without anyone noticing all this)...and at that point he turned around and started committing his crimes, pretending to work in the opposite direction by torturing that last person so he could 'find' the original letter, and use that to 'find' the person he wanted to kill..]]
** In "Scared to Death" it appears that the ghost of a serial killer is sending cursed [=DVDs=] to the people who testified against him, scaring them to death. It turns out not to be the case, obviously enough, but one thing is left unsolved after the real culprit is caught, what happened to his body? [[spoiler:Turns out, he was never buried, his body disappeared from the morgue and the coffin was buried empty. Were his claims of immortality true, did he find a way to survive his execution and escape, or did someone steal the body?]].
** In "Smells Like Teen Spirit", the various instances apparently involving telekinesis are all explained as special effects involving fishing line and magnets by the perpetrator. Except at the end Beckett mentions to Castle that they never found any of that in his house.
** In "[[Recap/CastleS7E6TheTimeOfOurLives The Time of Our Lives]]", an Incan artifact appears to send Castle into an AlternateUniverse where they never met. While at first it appears that ItWasAllADream, at the end of the episode Beckett arrests three murderers that Castle met in that universe, but had never seen previously, implying that the trip was real.
** In one episode, an attempted victim is believed to be the Antichrist by the villain. When Castle knocks the weapon away from him, he goes after it and a number of pipes fall on him. The supposed Antichrist comments on how lucky that that was, but it's left ambiguous whether or not it was just luck or if he used his demonic powers to cause them to fall.
* ''Series/{{Cheers}}'':
** An episode of involved a guy who wanted to be a priest, who was having cold feet one day before being ordered, who managed to touch an old piano in the bar that has been out of order by years. The piano worked! CloudCuckooLander Coach even says: ''“I can’t believe it”''. All the cast convinced the guy that it must be a signal that he was special and he must become a priest. He agrees and left the bar. When all comment the miracle, Coach says he repaired the piano a week ago. When they ask him why he said ''“I can’t believe it”'' if he knew the piano was working, he answered that all those years he left the piano broke without any further thought, ''but just a week ago he felt the irrepressible urge to repair the piano, before it was too late''.
** The episode "Fortune and Men's Weights" was much the same way; Coach bought and antique scale for the bar that also distributed a fortune-card with each weight reading. Carla believes this as true at once while the rest of the bar is skeptical. Over the course of a few days all fortunes it distributes come true, and even rational Diane begins to wonder about its potential power. Sam maintains it's just a machine and everyone's taking the idea too far. When Sam and Diane have a particularly rough fight that could endanger their entire relationship, he kicks the machine in anger. Diane insists the card may tell the future of if their being together is a good idea or not, Sam replies it's meaningless. At her coaxing he finally reads the card.
-->'''Sam:''' "Machine empty. Order more fortunes."
* Christmas episodes seem to be a breeding ground for this trope. It happens in a Christmas episode of {{Roswell}} when Max [[spoiler: heals an entire children's cancer ward]]. Possibly averted given Max's abilities, but the trope is largely played up in the show.
** ''Series/{{ER}}'' had an episode where a jolly, bearded toymaker comes in... and has mysteriously vanished by the end of the episode.
** ''ER'' also had another Christmas episode where Benton offhandedly touches a blind hypothermia patient's forehead, and said patient suddenly (and temporarily) regains his sight, causing several homeless people to station themselves in the ER to get "healed" by the "miracle worker". Benton [[GrumpyBear predictably brushes their claims off with annoyance]], but keeps getting his claim that it was just a coincidence weakened by random occurrences like a broken vacuum suddenly starting up again when Benton passes by. At the end of the episode, Benton still won't address the issue, but is told by Neurology that no one can find a medical reason for why the man got his sight back for an afternoon.
** ''Series/{{Cheers}}'' subverted this when no one in Norm's Department Store Santa class could identify the realistic Santa from their class, which caused Frasier (in full Ebeneezer mode) to ponder if it was the ''real'' Santa. When the Santa returns, he asks if anyone had a jump for his car. Frasier is still amazed and filled with the Christmas spirit because for a brief moment, he actually thought Santa Claus was real.
* ''Series/ColdCase'' does this at the end of almost every episode, often to [[TearJerker tear-jerking]] effect, with the "ghost" of the episode's victim appearing to either the detectives or someone they were close to in life. Normally, this ''could'' be written off as simply RuleOfSymbolism... except the living people actually seem to ''react'' to these apparitions. Notably, the victim in "Disco Inferno" manages to have a ''fully-choreographed dance number'' with his old girlfriend from beyond the grave.
* ''Series/{{Community}}'' has featured malicious robots, ghosts, telepaths, and evil alternate reality versions of the main characters. In all cases it's unclear whether the supernatural elements exist only in the characters' imagination. Ironically the zombie plague caused by infected meat, the one incident that almost definitely ''did'' happen, is the one [[LaserGuidedAmnesia no one can remember.]]
* In ''Series/CrazyExGirlfriend'', the [[SpiritAdvisor Dream Ghost]] shows Rebecca things that she should have no way of knowing, but claims to be a manifestation of her subconscious, so it could be that she already knew these things deep down. Heavily lampshaded in the song:
-->'''Dream Ghost''': It's not clear if I'm hallucinated or actually magic. Let's keep it vague; it's more interesting that way!
* ''Series/CriminalMinds'':
** The episode "With Friends Like These" features a man named Ben who seems to be haunted by three "demons" who nobody else can see, and who force him to commit murder. The detectives dismiss them first as drug-induced hallucinations and then as symptoms of schizophrenia, but both explanations are eventually ruled out and it’s left unclear as to whether or not they were real.
** The show makes sweet, sweet monkey love to this trope on a regular basis. Did the Satanic serial killer really have supernatural help, or was he just ludicrously lucky? Did the various psychics that the team encounter really have powers, or was it just a coincidence? Was [[spoiler: the bullet that killed Tobias Hankel]] really divine will, or was it just luck? Rossi gives a little speech at one point where he outright states that he has no idea whether or not the supernatural exists, but that figuring out the answer to that question isn't part of their job, and their job is tough enough as it is.
* The ColdOpen of a ''Series/{{CSI}}'' episode showing a psychic giving a reading that makes no sense to her customers, but it apparently turns out that she had foreseen her own death. Or she was a crappy psychic who was just looking around the room for random things to say and the connection of those things to her death were entirely coincidental.
* The entire point of ''Series/{{Cupid}}'', the 1998 version, was to be ambiguous as to whether Trevor was genuinely Cupid, or crazy. The 2009 version likewise fits with this trope.
* ''Series/DoctorWho'':
** The Doctor may have pockets that are bigger on the inside, but he may just cut a hole in his pockets through to the lining. Considering these explanations are given for two different costumes, it may even be both.
** [[Recap/DoctorWhoS28E8TheImpossiblePlanet "The Impossible Planet"]]/[[Recap/DoctorWhoS28E9TheSatanPit "The Satan Pit"]] featured Satan as a MonsterOfTheWeek. Is it really him, or just a SufficientlyAdvancedAlien who happens to resemble our popular conception of the Devil and perhaps was even the basis for our and other Devil myths? Never established for certain. For contrast, the original series story [[Recap/DoctorWhoS8E5TheDaemons "The Dæmons"]] (1971) had a similar MonsterOfTheWeek, which were explicitly SufficientlyAdvancedAliens.
** The episode [[Recap/DoctorWhoS34E4Listen "Listen"]] has the Doctor theorizing the existence of, and searching for, a creature that has evolved into the "perfect hider". In the end, the creature is never seen and every one of the situations encountered has a mundane (if occasionally farfetched) explanation ([[spoiler:of course, it's never revealed who it was under the cover in the foster home, or why Orson Pink would be so freaked out by something outside the hatch on a dead planet]]). Coupled with a revelation about why the Doctor is searching for the creature in the first place, the episode leaves it completely ambiguous whether the creature ever existed at all.
** In [[Recap/DoctorWho2014CSLastChristmas "Last Christmas"]], Santa Claus's appearance is ultimately confirmed to be part of an elaborate shared dream experience...but as Clara and the Doctor take off for more adventures, we see a tangerine left on Clara's windowsill...
*** Essentially, there are three possible explanations for Santa: 1) he's merely a dream construct; 2) he was the real deal; or 3) there ''is'' a Santa Claus in the Whoniverse, but the one in the episode wasn't the real deal.
* The ''Series/EerieIndiana'' episode "Heart on a Chain" is the only one in the series that never answers its mystery. A shy, terminally ill girl has a crush on a devil-may-care boy, who dies in a freak accident. A heart transplant from his fresh corpse saves her. She then begins acting increasingly bizarre (with a lot less self-control). It is left completely unclear until the end whether his heart's personality has taken over hers (as the AgentMulder believes), or whether guilt has made her [[NotHimself not herself]].
* In an episode of ''Series/EleventhHour'' (American), water that cured a boy's cancer proves to be heavy water. However, as the FBI agent points out at the end, this discovery leads to the arrest of domestic terrorists which otherwise would have gone completely unnoticed.
* The Wizard (specifically, his tools and other accomplishments) in ''Series/EmeraldCity''. While he definitely uses [[ClockPunk technology]], his giant stone statues seem a little bit... more advanced than the rest of his devices. He also is able to keep control of Oz and keep the Witches under control despite being (or appearing to be) a perfectly normal man.
* The ChristmasEpisode of ''Series/{{Eureka}}'' features Dr. [[MeaningfulName Noah Drummer]], whose experiment will supposedly bring "peace to Earth", but which actually saves the town and gives it a [[DreamingOfAWhiteChristmas White Christmas]], before he leaves, saying he has "an errand to run", but will be back at the same time next year.
-->'''Kid''': Sheriff Carter, please tell me you aren't saying this Drummer dude was [[SantaClaus Santa]]?
-->'''Carter''': I'm just telling the story. You can believe whatever you want.
** Drummer re-appears in the second Christmas Episode, in which he appears shortly after the holographic storybook that's controlling things has been told to add Santa to the story. As in the previous story, his influence is what gives the story its happy ending. He again refers to having errands to run, and has a dog-sled with a lead dog called Rudy.
** The crossover with ''Series/Warehouse13'' puts them into a universe that contains literal magic.
* In a more sci-fi spin on the trope, River's PsychicPowers from ''Series/{{Firefly}}'' are left very ambiguous, with minor hints pushing the audience and the characters to suspect that River can read minds. It's implied they would have been explored further had the [[ScrewedByTheNetwork show not been canceled prematurely]], and they are confirmed in the BigDamnMovie ''Film/{{Serenity}}''.
* ''Series/GameOfThrones'':
** Osha warns that the old gods cannot help the Starks in the south because the weirwoods there were all cut down, and as it happens no Stark who goes south has a good time.
** Was the red comet in "The North Remembers" an omen or just a coincidence?
** Beric Dondarrion's flaming sword breaks during a trial by combat. Did the fire weaken the steel, or did his god judge against him?
** Stannis performs a magic ritual cursing his rival kings. Robb Stark, Joffrey Baratheon, and Balon Greyjoy all die from various means, but it may just be coincidence. Furthermore, Stannis is killed by Brienne, but then the ritual was only meant to curse them, not protect himself.
* ''The Good Witch'', a series of made-for-TV movies on The Hallmark Channel, centers around an attractive woman (Catherine Bell) who relocates to a small town, moves into an abandoned house reputed to be haunted, and opens up a shop full of new-age/occult items, prompting the locals to suspect that she may be a witch. She never does anything overtly supernatural, but it's never confirmed that she isn't a witch either...
* There have been suggestions that ''Series/{{Hannibal}}'' might take place in a world where supernatural creatures exist as opposed to the strictly material world of previous adaptations. Aside from the idea that Hannibal himself is partly demonic in nature, the Angel Maker Killer in "Coquille" was taking medication for a brain tumor that might explain why he hallucinated his victims as being evil and killed them, but there was no way to explain how he could have known that his victims actually ''had'' performed acts considered evil.
* An episode of ''Series/HettyWainthroppInvestigates'' had Hetty hired to expose a psychic as a fraud and blackmailer. The psychic predictably uses cold reading techniques to find fodder, and Hetty uses her leading questions to make up a scandalous affair in her husband's past. However, the psychic does accurately describe a long-dead relative of Hetty's when supposedly searching for Hetty's dead husband, and obliquely predicts the birth of Hetty's grandchild, including hints to her name and health complications.
* Frequently in ''Series/HoudiniAndDoyle'', there's a wrinkle to the Mystery of the Week that isn't easily explained.
** [[spoiler:During the episode with the faith healer, Houdini suffers from symptoms that get worse every time he denounces God. After the healer loses his faith after learning that his sister had been attacking his hecklers, Houdini collapses and wakes up recovered. Also, Doyle's wife, who had awoken after the faith healer visited (despite Harry's insistence that it was the result of a seemingly failed experimental treatment), falls asleep again]].
** [[spoiler: "Spring-Heeled Jack": not all the attacks were perpetrated by the suspect who's arrested, with the last shot being of a possible second "Jack" watching the characters from a rooftop.]]
** [[spoiler:In the next episode, the medium turned out to have deduced the location of the first kidnapped girl through observations, and gone to the police so she could get to her, but how she knew both that Doyle's wife was still alive (in addition to her nickname) and where to find the information on Stratton's real identity is unexplained]].
** [[spoiler: "Bedlam": How did Doyle's hallucination of his father know about the liquor hidden in the piano?]]
** [[spoiler:We never see how the self-professed vampire lady got into and out of Doyle's home, nor how she broke Stoker out of jail. We also don't receive a solid explanation for how Stoker got out of the hotel. Stoker is also implied to himself be a vampire]].
** [[spoiler:Though a lot of what occurs with the Necro-phone is chalked up to either a deliberate hoax by the killer or the power of suggestion combined with coincidence, some of it, like Harry hearing his mother and the massive psychokinetic episode that occurs right before the device is destroyed, is more ambiguous]].
*** [[spoiler:There's also a mysterious woman following Houdini around, who almost seems capable of OffscreenTeleportation]].
* ''Series/{{House}}'':
** "House vs. God": A teenage faith healer somehow manages to shrink the size of a terminal cancer patient's tumor. By the end, it's revealed that the healer had herpes, whose virus has been known to combat cancer. However, as Chase points out, the odds of it being both the right strain of virus and the right type of cancer were astronomical, leaving the possibility of divine intervention open.
** In another episode, the team can't identify the problem of a priest who came in with hallucinations of Jesus and got more and more symptoms. He only manages to find the right diagnosis by deliberately ignoring the hallucinations, after which the patient is cured. This leaves the unanswered question of where the visions of Jesus came from if they weren't related to the patient's illness.
* The world of ''Series/TheLeftovers'' virtually runs on this trope. Several years before the start of the series, about 2% of the world's population vanished in an instant, with no explanation, and no discernible link as to why it was those people who vanished. Ever since then there has been a huge rise in {{Apocalypse Cult}}s, self-proclaimed prophets, psychics, faith healers, as well as people having visions or feeling that they have some greater divine purpose, etc. While most can be safely discounted, some appear to be genuinely propelled by supernatural elements, and telling them apart can be almost impossible. Sometimes even the people doing these actions aren't sure, for example in the finale of Season 1, a cult leader who had apparently successfully healed many people's minds tearfully confesses that he's not sure if his gift is real, or if he's just a very talented con man.
* The ''Series/LieToMe'' episode "Beat the Devil" has the verification of a UFO as its B-plot. Thirty-minute mark, they find (real!) video footage of it. Fifty-minute mark, an Air Force officer shows up, and Loker sees right through him to the truth: The Air Force has ''no idea'' what it was, but is more than happy to let the witness twist the story rather than admit to an unknown penetration of US airspace. They finally get the witness and the Air Force to agree on a story to save the witness' career: uber-uber-top-secret aircraft. Loker smiles and saves the video to hard drive as the episode ends.
* ''Series/{{Lost}}'' never definitively revealed the show's major mysteries as either essentially supernatural or essentially science fiction. The second-to-last season seemed to come down heavily on the side of science fiction, but the final season introduced plot elements that seemed balanced more toward supernatural explanations. Fans remain divided on whether the show ultimately came down on one side of the question, intentionally left things ambiguous to let each viewer decide, or was attempting a fusion of both SF and the supernatural.
* Not unlike the already mentioned [[ComicStrip/CalvinAndHobbes Hobbes]], we have the eponymous character of ''Series/McGeeAndMe'', an [[RogerRabbitEffect animated cartoon character]] created by the show's other main character Nicholas Martin. It's never really made clear whether or not [=McGee=] is a real character, just a figment of Nick's imagination, or someone who only Nick is able to interact with. Evidence for all theories exist over the show's run. [=McGee=] can apparently be seen by animals such as the family dog and a raccoon, sometimes has his own adventures separate from Nick, and can interact with real life objects to a certain extent. But on the other hand, [=McGee=] usually disappears when another person starts talking to Nick, nor is he ever seen by anyone else other than Nick.
* ''Series/MurdochMysteries'' does this occasionally, most notably with the possibly-NotSoPhonyPsychic in "Elementary, My Dear Murdoch" and the ReincarnationRomance in "Lovers in a Murderous Time".
* The show ''Series/MysteriousWays'' bases its entire premise on this, with a quirky teacher wanting to find a "smoking gun" of supernatural activity but always ending up with plausible but unlikely alternate explanations.
* ''Series/NannyAndTheProfessor'' introduced Phoebe, a nanny that arrives in America to tend to a widower and his family--''before'' they even know of her or that she is coming. In the first ten minutes of the show's pilot, Nanny greets an airport's agent, explains where she came from (England) and where she is going. However, the ''only'' flight coming from England that day had just arrived at the gate as Nanny walks away. Nanny's ability to speak to animals, her tendencies to know what is coming before it happens, and the like, is never explained. The character of Nanny is ostensibly a Film/MaryPoppins archetype, the magical/mystical housekeeper.
* A strange example in the usually reality-based ''Series/{{NCIS}}''. In the fourth season finale "[[ExactlyWhatItSaysOnTheTin Angel of Death]]", Dr. Jeanne Benoit encounters [[CreepyChild a little girl]] outside the hospital who may or may not be [[TheGrimReaper the Angel of Death]]. It's strongly implied to the viewer [[spoiler: that she really is]].
** In Season 13, we also get a very mundane explanation for Gibbs' copious RightBehindMe and StealthHiBye moments when [=McGee=] and [=DiNozzo=] are standing in a corner, discussing Bishop's marriage, assuming she can't hear them because they're too far away, only for her to reveal that she can, because their voices are reverberating off of the skylight.
-->'''[=DiNozzo=]''': "Wait a second. Is ''that'' how Gibbs is always able to---"
--> (right on cue, Gibbs appears out of nowhere)
-->'''Gibbs''': "--walk up behind you and finish your sentences?"
* ''Series/{{Proof}}'' runs on this trope, as the protagonist is a surgeon skeptical of the existence of an afterlife, despite having had her own near-death experience once. The billionaire Ivan Turing recruits her precisely because of her skepticism, and each episode deals with a unique mystery (often medical) with a seemingly paranormal bent. Usually, the episode ends with almost everything neatly explained, but some mysteries are left open to interpretation.
* Several episodes of ''Series/SevenDays'' play with the concept of supernatural but never outright confirm or deny it. One episode has a Brazilian shaman appear to cause a thunderstorm to appear out of nowhere to power a Sphere. Another episode has a voodoo practitioner possibly cause an execution to be stopped and the true villain punished. Yet another episode possibly implies that the villain (a chrononaut from years in the future, who attempts to kick-start WorldWarThree) may, in fact, be TheDevil. Then again, this is a show that uses alien technology to go back in time and has featured aliens several times, as well as a gremlin-like creature from another dimension. Various problems with the Sphere have also caused Parker to become the Pope, travel to the MirrorUniverse, mentally revert to his ten-year-old self, meet a dead person, and become a ghost himself. At that point, it seems pretty silly to outright discount the supernatural.
* In ''Series/SixFeetUnder'' it was generally clear that the visions of dead people the characters had were in their imaginations (as emphasized by e.g. Nate Sr.'s different behaviour depending on who saw him). Still, there were a few occasions with very slight hints that something more might be going on, as with [[spoiler: Claire meeting the dead Lisa, or Brenda meeting Nate Sr. (whom she'd never known while he was alive) or, hardest to otherwise explain, David and Nate sharing the same dream right before Nate dies.]]
* ''Series/TheSopranos'': When Christopher is writing the horror movie ''Film/{{Cleaver}}'', he mentions that its protagonist Michael rises from the grave, but doesn't decide whether it's done through technological or supernatural means.
* In ''Series/StarTrekDeepSpaceNine'', TheFederation explains away the Prophets (the divinities of the Bajoran religion) as [[SufficientlyAdvancedAliens wormhole-dwelling aliens]] with a strange relationship to time. The Bajorans reframe the Federation's talk of wormholes and aliens in terms of their traditional religious beliefs. The show demonstrates how each culture comes to different conclusions from similar evidence, without coming down firmly in favour of one interpretation over another. Sisko, a Star Fleet officer as well as the Prophet's emissary, likes to point out that since both groups acknowledge them as having the same abilities it doesn't really matter.
* In the ''Series/StarTrekVoyager'' episode ''Sacred Ground'', Kes was saved either by Janeway's leap of faith or though a series of coincidental natural phenomena {{technobabble}}d after the fact by the Doctor. (Another explanation is that the RubberForeheadAliens of the week were really SufficientlyAdvancedAliens who were just screwing with Kes and Janeway.)
* A particularly interesting example comes from ''Series/{{Supernatural}}'' Season 2 episode "Houses of the Holy", because the boys have no trouble believing in all kinds of weird and unexplained things, but Dean refuses to believe that angels or God exist. At the end of the episode, even after they've stopped the vengeful spirit from killing the sinful man it was after, Dean watches the man die in a freak accident, and admits the possibility that it was God's will. This becomes especially ironic at the start of Season 4 where Angels are not only confirmed to exist but one of them becomes a main character.
* ''Series/TrueDetective'', Season 1: Do the birds in the sky actually form a perfect spiral shape, or is Rust hallucinating? Likewise, what about the vortex Rust sees at Carcosa?
* ''Series/TheTwilightZone1959'':
** The episode "The Thirty-Fathom Grave". A U.S. Navy destroyer crew investigates a strange knocking sound coming from a submarine sunk years earlier. One of the ship's crew escaped the sinking sub and feels SurvivorGuilt: he thinks his old crew is angry at him because he didn't die with them. At the end it's revealed that an object inside the sub ''could'' have been making the knocking sound. But was it the periscope or the hammer in the drowned sailor's hand?
** The episode "The Grave", apparently based on a similar well-traveled urban legend. A cowboy in the Old West visits the grave of his enemy on a bet, the dying man's own last words having been an assurance that if he went anywhere near the grave, the dead man would reach up and grab him. As proof, he has to plant a dagger into the plot. When he finally musters the courage to do so, you can't see what's happening but * something* snags him and he goes down stiffly, mostly off-screen. The next morning his corpse is found there by the townsfolk. He had had a heart attack and the dagger was pinning his garments to the ground, perhaps having been blown into his path by the wind, causing him to have mistaken the situation for the obvious supernatural substitute when he found himself snagged upon trying to turn away. But one of the people observes that "the wind was blowing in the opposite direction". The closing narration says that it's up to us to decide what to believe.
** "Nick of Time" had its protagonists consider whether a penny fortune-telling machine could truly answer any yes-or-no question correctly, or if it was merely on a lucky streak. People who continue to believe in the machine are shown to stay in town and continue feeding in pennies for fear of their lives. Is it only paranoia, or does the mystic seer use real power to gain addicts?
* In an episode of ''Series/WalkerTexasRanger'', a young man steals a priceless jade statue from a Triad gang, believing it has magical powers that can wake his sister from her coma. Walker dismisses this as nonsense, but defends the man from the vengeful gang. The man presents the statue to his sister and nothing happens, but she does wake up when the statue breaks. Walker treats this as a coincidence. It is implied that the statue did have magical powers, as it glowed in the presence of people who could channel their chi like martial artists.
* In ''Series/{{Warehouse 13}}'', the basis of the show is powerful artifacts that produce near-magical effects. That's not the trope (although the organization does store them under the theory that [[SufficientlyAnalyzedMagic someone will figure them out eventually]]). No, this trope comes into play because most artifacts were owned by famous historical figures well-known for something similar to what the artifact is capable of. It's never made clear whether their extraordinary skills created the artifacts, or if they became famous because they made use of the artifacts.
-->'''Artie:''' Maybe it worked on her, maybe she worked on it...the point is, it ''worked''.
* The BBC/Starz series ''The White Queen'' portrays Queen Elizabeth (the consort of Edward IV, not the more famous daughter of Henry VIII), her mother, Jacquetta Woodville, and her eldest daughter, also named Elizabeth, as actual witches with real magic powers. Except the show does leave a little ambiguity, since it is possible that all the spells we see them cast appear to work purely by coincidence. For example, when they cast a spell to cause a storm, it is possible that the storm would have occurred naturally anyway. Still, considering that every spell they cast seems to produce its desired result, this would be an amazing series of coincidences.
* In ''Series/TheWholeTruth'', [[{{Series/Oz}} Harold]] [[{{Series/Lost}} Perrineau]]'s character is accused of murder because he leads police to a body and claims he knew where it was because he's a psychic. While he does appear to know things which he couldn't have without special powers, evidence is also given that he could have [[PhonyPsychic faked it]] as well. It's left unresolved either way.
* Is ''Series/{{Wilfred}}'' the product of Ryan's imagination, or some sort of paranormal occurrence? Wilfred himself loves to keep it ambiguous just to mess with Ryan.
* This happened in a very large number of episodes in ''Series/TheXFiles''. Examples include these episodes:
** The killer in the episode "Grotesque" is eventually revealed to be a [[TheProfiler profiler]] who looked too long into the abyss of a particular serial killer and turned into his copy cat. Whether this is a psychological effect or transferred demonic possession is left up to the viewer.
** "One Breath": Who or what was the nurse attending to the critically ill Scully? The supervisor said there was no "Nurse Owens" working at the hospital, and no one matching that decription. We never do get an answer. Was she an angel? A member of the conspiracy planted there? One fanfic proposed she was a friend of [[TheLoneGunmen Frohike]] sneaked in so ''someone'' trustworthy was watching.
** "All Souls": It's left unclear whether Agent Scully's dead daughter Emily was really appearing to her or Scully was hallucinating.
** "Irresistible": Donnie Pfaster's shape shifting into demonic forms might have been really happening, or people who saw him were hallucinating from stress and fear. [[spoiler:"Orison" leans very heavily towards "really is some kind of demonic monster".]]
** "Paper Hearts": Perhaps Agent Mulder and serial killer Roche really shared a PsychicLink which allowed Roche to get into Mulder's head. He really read his mind and saw his memories. Perhaps he just found information about Mulder on the Internet and then simply managed to manipulate him.
** "The List": It's not clear who was responsible for the murders. Either there was an elaborate conspiracy that bit all people involved in the butt, or the executed prisoner reincarnated and came back, perhaps as a fly.
** In "Quagmire," the monster behind the killings turns out to be just a really big crocodile. (The final scene, however, revealed that [[RealAfterAll there actually]] ''[[RealAfterAll is]]'' [[RealAFterAll a plesiosaur-like creature living in the town's lake.]])
** Also subverted in "War of the Coprophages". There really are robotic alien cockroaches scuttling around, but they're not responsible for any of the deaths in the episode, all of which are either coincidental or the result of mass hysteria.

* The old folk song "Scarlet Ribbons". The narrator overhears his/her young daughter praying for scarlet ribbons for her hair before bedtime. Unfortunately it is very late, and all the shops are closed, making it impossible to obtain them. When the narrator checks on his/her daughter again before dawn, [[spoiler:the wished-for ribbons are lying on her bed.]] The song ends with the lines [[spoiler:"If I live to be one hundred / I will never know from where / Came those lovely scarlet ribbons / Scarlet ribbons for her hair."]]
* The Presence, in the Music/NineInchNails ''Year Zero'' ARG. In a dystopian future, suddenly a giant glowing blue human arm is periodically seen reaching down from the sky, in locations all over the world. No clear explanation is ever given for what the hell the Presence actually is, but what is known is that it will never appear on video or photographs intentionally taken of it, while those that accidentally capture it can, and that anyone who witnesses it is unnaturally stunned by the sight of it. In-universe theories range from the Presence being God, aliens, or a government weapon, but none of these are ever confirmed before [[spoiler:it destroys the world.]]
* "Rosetta Stoned" from Music/{{Tool}}. The narrator is clearly having a full-scale breakdown, but the cause is what's open to interpretation. Did he really have a sanity-destroying encounter with aliens who informed him that he had some [[TheChosenOne greater cosmic purpose]], or did he just have a ''really'' bad trip? Given Maynard's [[ShrugOfGod attitude]] towards giving a straight answer about a song's meaning, either interpretation could be correct.
* In "Creepy Doll" by Music/JonathanCoulton, it's not entirely clear whether the titular doll is magical or merely the focus of [[SecondPersonNarration your]] growing insanity.
* Music/JobForACowboy's ''Sun Eater'' is either chronicling a psychedelic trip (based on the nature of the visions and the album's musical flow, probably ayahuasca) or a wisdom-granting seance. "Worming Nightfall" is either where the trip goes very wrong and destroys the protagonist's mind or where the seance goes wrong and leaves her trapped in a dream world. The wording is ambiguous enough that both explanations are equally plausible.

* In Alfred Noyes's "Forty Singing Seamen", it concludes with the narrator's observation that might all be PinkElephants. To be sure, that included drinking the grog.
-->''Across the seas of Wonderland to London-town we blundered,\\
Forty singing seamen as was puzzled for to know\\
If the visions that we saw was caused by--here again we pondered--\\
A tipple in a vision forty thousand years ago.\\
Could the grog we ''dreamt'' we swallowed\\
Make us ''dream'' of all that followed?\\
We were only simple seamen, so of course we didn't know!''\\
'''Chorus'''--''We were simple singing seamen, so of course we could not know''
* In the ballad "Literature/TheErlKing" by Creator/JohannWolfgangVonGoethe, a sick boy claims he is being pursued by the Erl-King who wants to take him away; shortly after claiming that the Erl-King is touching and hurting him, he dies. The poem does not answer the question whether the Erl-King was real or only the dying boy's fever dream.
* In "Literature/LoreLay" by Clemens Brentano, Lore Lay is called a sorceress, and is charged with using magic to make all men fall in love with her. However, the fact that Lore Lay is not actually interested in the attention she receives suggests that she may not be a witch at all, merely a very attractive (but non-magical) single woman.

* One ChristmasEpisode of ''Radio/TheMenFromTheMinistry'' ends this way; the episode features One upsetting Santa and the main duo travelling to Christmas Land and escaping eventually on an magic carpet. The episode ends with [[AllJustADream Two awakening One from a sleep]], but a new red carpet has appeared on Two's room...

[[folder:Tabletop Games]]
* ''TabletopGame/Warhammer40000'' loves this trope as a cornerstone of its setting, especially when the Adeptus Mechanicus come into play. Is that ancient relic so powerful because it was created with long-lost technology of astounding power, or is it truly blessed by the Emperor to protect his children? Do the Necrons invoke some strange techno-sorcery in their weapons and vehicles, or is their understanding of the material world so absolute that we can't even begin to understand how they work? Are the Legion of the Damned mystical undead, or just regular marines suffering from some ungodly mixture of the Black Rage and Nurgle Rot? Did the Techpriest's chanting and ritual application of holy oils appease the machine spirit of the Land Raider, or does the Land Raider just have a voice-activated diagnostic program installed? The answer is very, very rarely made clear in any given case. This is made worse because it has to be on a case-by-case basis since magic and super-tech both exist in the setting, and some tech (especially that used by Orks) is explicitly a mix of real mechanical systems and ClapYourHandsIfYouBelieve.
* ''TabletopGame/MageTheAscension'' had some fun with this too. Any smart mage makes their spells look like coincidences, hypertech, or something else that the general population believes will work (and a fair number actually believe that this is what is happening). With the heavy levels of ClapYourHandsIfYouBelieve used, the odds are very good that there's a bit of both magic and coincidence/super-science/whatever going on.
** The really mind-bending part is that the universe is designed to behave, mechanically, the way the mage thinks it behaves (the 'paradigm' mechanic), so a scientific test devised to determine whether something is one or the other will always empirically show that it's "magical" (whatever that means to the mage's paradigm) so long as it's the mage performing the test. Technology that appears to be "non-magical" isn't actually mundane, it's part of The Lie that the Technocracy has spread to suppress direct will-work.
** The ''TabletopGame/NewWorldOfDarkness'' sourcebook ''Asylum'' presents a suite of odd happenings and disturbed individuals in the ill-starred Bishopsgate Mental Hospital in one chapter. The book gives each of them one or more supernatural explanations... and also gives a mundane one for each, with the "real" answer in the Storyteller's hands. (For example, one of the patients is a woman with foggy memories and terribly-kept medical records. The book gives two possibilities: she's being used as a storage conduit by [[TabletopGame/MageTheAwakening the Seers of the Throne]], who alter her records to hide their activities... or she's just an ill woman with an aneurysm on the verge of bursting, and the hospital's just really screwed up keeping their books straight.)
* ''TabletopGame/DungeonsAndDragons 3.5'' edition has a PrestigeClass that pretends to be a spellcaster, stretching sleight of hand and really good bluff skills right to the edge of the supernatural.
* ''TabletopGame/{{Pathfinder}}'' ups the ante on this a bit by giving rogues (the "tricky" non-magical CharacterClass) access to actual spells as class "tricks". Because they're so good at faking it, sometimes even the universe just gives up and believes them.
* ''Tabletopgame/BattleTech'''s "[[StealthyColossus Phantom 'Mech]]" ability, which was displayed in the ''BattleTechExpandedUniverse'' but also given rules in the tabletop during three different scenario sets. In combat, Morgan Kell's, Patrick Kell's and Yorinaga Kurita's [[HumongousMecha battlemechs]] became completely invisible to sensors, and targeting systems were completely unable to detect them. Attempting to fire upon them resulted in the weapon missing entirely, unless they engaged each other, or someone got both fancy and dumb. (Daniel Allard successfully hit Morgan Kell by having his 'Mech's computer fire at the flashes of Morgan's lasers; he said himself this was low-probability to work if Morgan had been moving.) It's never explained what exactly it is; whether it be destiny, or a [[LostTechnology LosTech]] stealth system. The fact Morgan was apparently able to do it against the Clans again during the Battle of Luthien argues against it having been lostech, though.
* The Fate systems such as [[TabletopGame/TheDresdenFiles Dresden RPG]] and Strands of Fate have the Aspect system where all characters have a set of "Aspects" which basically causes [=PCs=] and other important characters to have a serious case of PlotHappens in their general vicinity. Leaving you to wonder in some settings whether there is something special about these people.
* ''Remnants'' goes so far as to quote both ClarkesThirdLaw and the misattribution to Larry Niven that gave us SufficientlyAdvancedMagic, and offers both magical and technological explanations for the disaster that broke the Broken Lands and left only ruins and self-repairing mechs.

* ''Theatre/TheWintersTale'' by Creator/WilliamShakespeare: At the end, Queen Hermione's statue seems to come to life. It could be that the statue of Hermione really does come to life, or it could be that her servant, Paulina, kept her hidden for years and she only claimed she had died.
* ''Theatre/NextToNormal'': In the end, although the family does begin to heal and move on, it's left a bit unclear whether Gabriel was just a hallucination or actually was a ghost desperately holding onto Diane to keep "living". The reprise of "I Am the One" could easily support either conclusion.
* In ''Theater/ThePhantomOfTheOpera'', it's deliberately left ambiguous as to whether the Phantom actually does have supernatural abilities. Some of the things he does, like the mirror, are understandable, but a lot more - causing the piano to play itself during the rehearsal of Don Juan Triumphant, creating fire in the graveyard, making the gates in his lair rise with merely a gesture, disappearing from under his cloak at the end of the show - while obviously stage effects in real life, have no practical explanation in the context of the story. However, the film version makes it very clear that all the stunts he pulls are merely clever tricks, leaving the more supernatural stuff out altogether and explaining other things away by showing the Phantom pulling a lever to raise the gates, or messing with Carlotta's throat spray in order to make her croak.
* In the musical version of ''Theatre/{{Heathers}}'', Veronica sees ([[DeadPersonConversation and talks to]]) the ghosts of [[SerialKiller her boyfriend's]] victims multiple times throughout the show. But since only Veronica sees them, and she gradually grows more and more unstable, it's left up to the audience to decide if the ghosts are really there or just a hallucination. At one point, the ghosts warn her of danger, but that could also be chalked up to Veronica's gut feeling, especially considering she was ProperlyParanoid already. Essentially, it's up to you whether the ghosts caused Veronica's SanitySlippage, or if it was the other way around.

[[folder:Video Games]]
* In ''VideoGame/{{Scratches}}'' you are constantly bombarded with a mix of "magic" and "mundane" arguments up until the very end, and it's still not entirely clear which one was at work: Was there ever a curse in the mansion, or was it all just the result of a series of terrifying misunderstandings? Made even scarier when you consider that the mundane explanation behind the mystery is, arguably, at least as terrifying as the supernatural one.
* ''VideoGame/MetalGear'':
** ''VideoGame/MetalGearSolid2SonsOfLiberty''. Among many, many other examples, there is Fortune. Is she ImmuneToBullets due to luck-based powers, or a prototype force field? If it's the force field, then why can she deflect missiles after the force field has been proven to be deactivated? Also, she managed to survive a gunshot wound due to her being one of a very few number of people with their hearts on the opposite side of their chests...
** Another example that is frequently debated by the fans is the nature of Ocelot's "Liquid Ocelot" persona. While Big Boss explains it in ''VideoGame/MetalGearSolid4GunsOfThePatriots'' as solely the product of nanomachines and Ocelot's self-induced psychotherapy techniques, it's less clear about the Liquid persona in ''Metal Gear Solid 2'', when he still has Liquid Snake's right arm grafted to him. Even though Big Boss says that "an arm can't do that" in regards to Liquid's supposed possession of Ocelot, there is the fact that Ocelot's father is a spirit medium in ''VideoGame/MetalGearSolid3SnakeEater'' (something Big Boss may be unaware of), and he seems to be far less in control of "Liquid" in ''[=MGS2=]'' than he is in ''[=MGS4=]'' after Liquid's arm is replaced by a cybernetic one.
* ''Franchise/DragonAge'' uses a variant on this trope with Andraste, the backstory's expy of Joan of Arc and Jesus. The church's doctrine is that she genuinely enjoyed the favor of the otherwise absent Maker and through her, the Maker wrought miracles - and that Andraste's ashes in ''Origins'' have genuine miraculous power. It's suggested, however, by non-church characters, that Andraste may simply have been a powerful sorceress who fooled the world and that her ashes have power as a result of being stored near a massive deposit of incredibly pure [[GreenRocks lyrium]]. As with all things related to the Chantry's doctrine in-game, the writers leave the truth intentionally ambiguous.
** A variation in ''VideoGame/DragonAgeII'': why there are constant problems in Kirkwall? Is it because the city's layout was set down to create powerful sigils for some unknown purpose? Something the Tevinter Mages did when they controlled the City or some curse bestowed when they lost it during the slave uprising? Is it because the Veil between the Fade is particularly weak there? Maybe its proximity to the [[spoiler: Primeval Thaig and vast amounts of Red Lyrium that drive people crazy?]] Maybe its proximity to the [[spoiler: Ancient Darkspawn Corpypheus]] slumbering in [[spoiler: his Grey Warden Prison?]] Or maybe its because the people who live there just make it a CrapsackWorld?
** Just what the hell is up with Sandal and why does he keep being found surrounded by countless dead Darkspawn, Demons, etc?
--> '''Hawke''': I'd really like to know how you killed all those darkspawn?! \\
'''Sandal''': *''Hands them a Runestone''* '''Boom!''' \\
'''Hawke''': And how did you do ''that?!'' *''Gestures to a Ogre frozen-solid and in mid-charge''* \\
'''Sandal''': '''Not''' Enchantment!
** There are a number of [[EpilepticTrees fan theories]] surrounding Sandal. Dwarf who has somehow learned to use magic? [[note]]But that's impossible, Dwarves cannot use magic in any way (well, actually, some older thaigs have made this dubious....[[/note]] [[PhysicalGod Old God]] manifested in the form of a Dwarven boy? [[note]]Remember, he ''was'' found in the Deep Roads, miraculously unharmed[[/note]] And what's with [[http://www.youtube.com/watch?v=cwa-mKETJW0 this weird line]] he spouts in ''Dragon Age II''?
** ''VideoGame/DragonAgeInquisition'' gives the whole "Is it really TheMaker acting InMysteriousWays?" question another spin with the story of the Inquisitor, a.k.a. the Herald of Andraste (a.k.a. the PlayerCharacter). Are they really guided by some divine providence, or is it just sheer, blind luck that saves them again and again where anyone else would have died horribly? Either way, it is pretty obvious how history will remember them (hint: take a good long look at Andraste).
* ''VideoGame/TheElderScrollsIIIMorrowind'':
** The game is very ambiguous on whether the PlayerCharacter really is the Nerevarine — prophesied hero and reincarnation of the long-dead Dunmer FolkHero. It's also possible that you're a particularly clever and lucky impostor who tricked everyone with the help of TheEmpire ''and'' Azura, a [[OurGodsAreDifferent Daedric Prince]] who was the original Nerevar's patron in ages past. The game [[TheUnreveal never answers it definitively]] ( and it even throws in the third possibility of you ''[[BecomingTheMask becoming]]'' the Nerevarine by doing what the Nerevarine is prophesied to do), and the most knowledgeable (sane) beings in the setting prefer not to jump to any conclusions about you.
** The original Nerevar in the {{Backstory}} was said to possess "supernatural powers of persuasion'', which were further enhanced by his enchanted Moon-And-Star ring. Were they some sort of supernatural gift or was he simply a very persuasive person? Like many other details about him, this one is likely lost to history.
* The ''VideoGame/HalfLife2'' GameMod ''VideoGame/BlackSnow'' plays with this trope a lot. It's revealed the eponymous black snow is a [[spoiler:heavily parasitic and aggressive form of spore-based fungus]] that is immune to most environmental hazards ''but'' regular light and above, but that doesn't explain the strange whispering and noises it emits, the ghastly groan it makes when it attacks, the mysterious presence of a Slenderman-like figure in drawings made by the research staff [[spoiler:who shows up on a laptop's wallpaper while you're searching it for files and in a sensory deprivation chamber's induced hallucination]], the bizarre fossil core that it seems to emanate from when it was dug up, [[spoiler:that it seems to be actively screwing with the player character's camera in the ending by plastering what appears to be the faces of the researchers of the center it attacked and images of a cave...]]
* Takane Shijou of [[VideoGame/TheIdolmaster The iDOLM@STER]] is implied to be from either the Moon... or Germany.
* Similar to the ''ComicStrip/CalvinAndHobbes'' and ''Film/FightClub'' examples above, ''VideoGame/SilentHillShatteredMemories'' leaves players on a note of ambiguity regarding whether [[spoiler: Harry was a physical manifestation of Cheryl's memories wandering through the real (or alternate-dimension) Silent Hill, or purely a figment of her imagination navigating an equally imaginary world.]] The creators are [[ShrugOfGod vehement that players should come up with their own answers]], and ample evidence exists for both interpretations.
** Pretty much every entry in the ''Franchise/SilentHill'' franchise plays this trope. In each one, it's intentionally unknown if [[spoiler: all of the monsters, characters, Otherworld transformations, weapon/item placements, and strange scenery pieces that Harry/James/Heather/Henry/Travis/Alex/Murphy encounter are either legitimately happening and being fought with, or are all merely drug-induced halleucinations or bad nightmares; the [[VideoGame/SilentHill1 first game]] alone demonstrates as much evidence of the cult's White Claudia drug smuggling operations as there is talk of the town's still-mysterious past, Alessa's "strange powers", and the cult's creepy rituals. One of the endings for that game even suggests it was all a dying dream, but is considered non-canon.]] Perhaps most bizarre of all, however, is that a cutscene towards the end of ''VideoGame/SilentHill3'' has [[spoiler: Vincent remarking "They looked like ''monsters'' to you?", suggesting both the hallucinations-possibility again...and that our protagonists may actually be killing innocent people or cult members instead! Of course, he says he was joking afterwards, but nobody knows even to this day...]]
** Also from ''Silent Hill 3'' is the [[spoiler:true nature of Leonard Wolf. When Heather encounters him, he appears as a large, aquatic beast.]] Despite this, Leonard's daughter is completely human, and no character ever mentions anything unusual about Leonard's appearance. It is possible that Heather was instead seeing ThroughTheEyesOfMadness? Or did he [[AndThenJohnWasAZombie become a monster]] due to his connections to the cult?
* ''VideoGame/{{Fallout}}'':
** In ''VideoGame/Fallout2'', there is a town wherein you can meet a translucent woman who claims to be a ghost, but in dialogue you simply ask her to turn off her Stealth Boy, an item from the first game which, well made the user translucent and thus harder to see (hence the name). So is this just a mentally disturbed woman with Stealth Boy, or an actual ghost? ''VideoGame/FalloutNewVegas'' shows that prolonged usage of Stealth Boys among Nightkin has made them schizophrenic, giving evidence to the former. However the effect has never been observed among humans…
*** Hakunin is a shaman like member of the Arroyo tribe who can speak to the Chosen One through his dreams. In universe, people with these powers are known as Psychers. Whether his powers are supernatural or the result of some radiation induced mutation are not explained.
** There's a lot of fucked-up stuff that goes on in [[Creator/HPLovecraft Dunwich Building]] in ''VideoGame/Fallout3'' that can be rationalized as, say, hallucinogenic gases, or maybe an odd variant of radiation, but that explanation still doesn't cover everything. It's entirely possible that the Dunwich Building is perfectly normal- well, as far as 'normal' goes in Fallout. But it's also entirely possible something dark and eldritch lurks there. We'll never know for sure.\\
This goes even further and yet also stays precisely the same in a mission in the expansion pack. You're asked by a somewhat creepy old man to retrieve a book - supposedly, a tome of eldritch lore. You're asked by an old Christian missionary to destroy it by pressing it against the monolith in the basement of the Dunwich Building, which will destroy the book. It's entirely possible the book is made out of some strange radioactive substance that reacts poorly to whatever the monolith is made of - or it might actually have genuine arcane power.\\
The Point Lookout DLC had some DummiedOut plot points regarding the book according to TheOtherWiki. Apparently Obadiah Blackhall was specifically asking for the help of the Christian Missionary to help him destroy the book, when she receives the notification of this she proclaims that Obadiah is a good man but comes from a bad family. When the book is brought to him Obadiah was supposed to tell you that the book was used by his family for occult purposes in ancient times and that it has demonic origins, he explains that there are two ways to destroy the evil magic contained in the book; either sacrifice himself or destroy the book in the Dunwich Building. This cut content makes it far more explicit that the book is magic.
* It's unclear [[MindScrew how much is real and how much imaginary]] in ''VideoGame/RuleOfRose'', but a pretty standard interpretation is that all the supernatural events are in the protagonist's badly muddled head, and it was AllJustADream, albeit of real events.
* ''Franchise/FiveNightsAtFreddys'':
** The killer animatronics zigzag this throughout the series. While the stated reason for their behaviour in [[Videogame/FiveNightsAtFreddys the original game]] is that an error in their programming that causes them to perceive the player as an endoskeleton sans costume, an EasterEgg notes that [[spoiler:after five children were lured into a room and disappeared, the animatronics began to smell and leak blood and mucus]], suggesting a more paranormal cause. [[Videogame/FiveNightsAtFreddys2 The sequel]] makes it obvious that there is something more than human going on with them, and ultimately ''Videogame/FiveNightsAtFreddys3'' directly confims that the animatronics [[spoiler:are possessed/haunted by the ghosts of the dead children]].
** ''Videogame/FiveNightsAtFreddys3'' has phantoms of the animatronics who, while not lethal, pose an indirect threat. It's never clear if they're hallucinations brought on by fear/shoddy ventilation, or if they are indeed "phantoms" of some kind.
** In ''VideoGame/FiveNightsAtFreddys4'', are the Nightmare animatronics just [[spoiler:the hallucinations/PTSD-induced flashbacks of the Bite of 87's victim, or actual entities that can kill him? Is the child's Fredbear just a plush toy, or a NotSoImaginaryFriend responsible for the Nightmares in the first place?]]
* In ''VideoGame/MichiganReportFromHell'', it is heavily implied that the monsters in the game are a result of experiments, with plenty of evidence to back it up, however, at the same time, you can find strange things, such as bed-sheets floating as if ''someone'' is laying down in them, an oven being on even though the place is abandoned (though whether or not it was left on ''recently'' is another unanswered question), and a few other things, these possibly implying that there are unnatural forces at work.
* VideoGame/SherlockHolmesTheAwakened: The various Cthulhu-related elements are treated this way. It could be the Great God himself causing storms and the end of days, or simply a very large number of crazy people. The best example is when Sherlock uses an incantation said to exorcise demons to subdue a gunman. It may have worked, or it might have just his own beliefs working against him.
* ''Franchise/{{Pokemon}}'':
** Many [[OurGhostsAreDifferent Ghost-type]] Pokémon have Pokédex entries that are akin to, well, ghost stories. These include Yamask being the soul of a dead human that carrys a mask of its old face, Phantump being the soul of a child lost in the woods, and Banette being a doll with a grudge against its owner. Despite that, the Pokédex has been known to make dubious statements (such as claiming Magcargo's body temperature is 18,000°F -- higher than the surface of the sun), so some fans take these entries with a grain of salt.
** In ''VideoGame/PokemonRedAndBlue'', did that girl in Lavender Town really see a white hand or was she just teasing?
* ''VideoGame/{{Bully}}'' has various [[http://strangegaming.blogspot.com/2011/12/unexplained-strangeness-in-bully.html clues, hints, sightings, and sounds]] that there is a werewolf loose in town, leading to lots of online controversy in the gaming world, making some gamers wonder who that werewolf is, and making other gamers claim that there is no werewolf at all.
* ''VideoGame/FarCry3'' has this all over it. So many things on the island, like the animal's ultra-aggressive, almost HiveMind-like behaviour, [[spoiler:Jason's prophetic hallucinations]], [[spoiler:the alleged "demon" Jason fights about halfway through the game]], an NPC who is heavily implied at the end to have been a ghost, the way [[spoiler:the local natives seem to be slowly going mad]], old letters from WW2 Japanese soldiers reporting crazy shit going on... The list just goes on, and the worst thing is, in true trope form, we're just left to wonder if it's all real, or the protagonist simply going insane. And there's plenty of evidence for both. It's border-line terrifying.
* ''VideoGame/FarCry4'' continues this. Ajay has several visions of an ancient Kyrati warrior questing for Shangri-La who he may well be a reincarnation of, but he's mostly tripping balls on drugs when this happens to him. The ''Valley of the Yetis'' [=DLC=] also does this with the eponymous Yetis, [[spoiler:the insane religion of Yalung, and the Relic]].
* In ''VideoGame/AttackOfTheFridayMonstersATokyoTale'', while some of the strange goings-on are given definite natural explanations ([[spoiler:the monsters that had been appearing are just stagecraft made by the local TV station]]), other aspects of the plot tend to be more ambiguous about whether they're real events or fantasies of the game's child characters, particularly as the adults act like it's all real while the kids are around. And some of the stranger happenings don't get any naturalistic explanations at all ([[spoiler:such as Sohta's abduction by the UFO and transportation to the diner]]).
* In ''VideoGame/MedievalIITotalWar'', priests (of all types, Christian, Muslim, Pagan, doesn't matter) with a higher Piety rating have a greater survival rate against assassins. Why is this? Is it merely because a higher-ranking priest would have more competent bodyguards in greater numbers, or is it that the priest is viewed so highly by the community that Assassins dare not [[MoralEventHorizon attack him]] [[http://en.wikipedia.org/wiki/Thomas_Becket for fear of reprisal?]] Or does his piety actually give him divine protection?
* Similarly to the ''Medieval II: Total War'' example, a number of events in the ''VideoGame/CrusaderKings'' games are seen by the ''characters'' as explicitly supernatural or miraculous, but could have more plausible explanations. To give but one possibility: Is your king genuinely suffering from DemonicPossession, or are the [[HearingVoices voices in his head]] simply the result of a mental disorder medieval medicine knows nothing about? After a number of [=DLCs=], the second game has options for an explicitly mundane world or undeniable MagicRealism, though there remain plenty of events ''believed'' to be magic by the denizens of the world in the first case, and a number of ambiguous events in the second.
* In the first section of ''VideoGame/MassEffect3'', [[PlayerCharacter Shepard]] runs across a young boy in a half-ruined building, has a few lines of conversation with him, and then has to leave. Later, the same boy is spotted climbing into a shuttle which is promptly shot down. End of story? Maybe... but between his seemingly impossible StealthHiBye (Shepard turns away for a few seconds, and he climbs out of sight -- in an air vent), his [[VaguenessIsComing vague, panicky dialogue]] that is totally ''correct'', the fact that no one else seems to see him or ever interacts with him -- not Anderson, not anyone on the shuttle he's climbing aboard -- and not least [[spoiler: the Catalyst at the end of the game coincidentally (?) basing its avatar on him]], well, things seem a little fishy. Naturally, [[EpilepticTrees fan theories hopped the first train out of Rational Town and never looked back]]. Well, theories of [[BrainwashedAndCrazy indoctrination]] are ''technically'' mundane in this sci-fi setting...
** A more obvious example is the Citadel DLC's culmination to Thane Krios' RomanceSidequest: is the [[spoiler: ghost of him that Shepard sees an actual spirit of the dead, or her going mad from stress?]]
* ''VideoGame/NightInTheWoods'' lives and breathes this tropes constantly, to the point it's impossible to be sure about what happened in the end of the game.
** The Janitor is a recurring figure that appears and gives Mae cryptic sentences that seem like either warnings or helpful advice. The end reveals that he [[spoiler:knew Mae's name all along]]. There is a lot of ways to explain what he does, several simply being that he is an old and wise man that has taken a liking on a girl who really look like she needs help, but it's left ambiguous whether [[spoiler:he is or not a supernatural entity, with hints that he might actually be God himself]].
** The latter part of the game is focused on a ghost hunt, but the characters themselves lampshade the possibility that it's actually just a normal person that has done everything.
** Mae has recurring nightmares of a astral band in strange places that always end with she meeting a gigantic and bizarre creature. It's hinted at the possibility that Mae has some sort of connection to the supernatural and that those entities are some sort of CosmicHorror, but the nature of these dreams and things are ultimately left unexplained. There is genuinely a possibility that Mae is sick and is hallucinating in her nightmares, [[spoiler:not helped that the end of the game confirms she has some sort of psychosis, with symptoms of dissociation and sleep paralysis]] and one of the newspaper in the library reveals that there was some sort of gas leak in town that makes people hallucinate.
* When Wardog pull a LetsGetDangerous moment mid way through ''VideoGame/AceCombat5TheUnsungWar'' the enemy freaks and believe the Demons of Razgriz (a mythical tale part of the game revolves around) took over the pilot's bodies. The squadron runs with the idea later on and renames themselves Razgriz, but whether or not the myth is true is left up in the air.
* ''Red Dead'' series:
** In ''VideoGame/RedDeadRedemption'', a side quest has Marston meeting up with a mysterious stranger who seems to know an awful lot about him while also remaining impervious to bullets. Is this man some sort of supernatural entity? Is he all in Marston's mind? The game isn't really clear on that one.
** Some of the bosses in the previous game, ''VideoGame/RedDeadRevolver'' count. One can teleport, one can move at extreme speeds, one has an army of zombies...
* ''VideoGame/ZeroSummer'' has bat-things that fly through the sky each night. Are they demons? Aliens? Actual bats? [[RiddleForTheAges Nobody knows.]]
* ''VideoGame/AssassinsCreedSyndicate'' has a few side missions featuring Spring-Heeled Jack, and it is left ambiguous if he's a truly supernatural being or simply using theatrics to fake it.
* VideoGame/RiseOfTheTombRaider has DLC centered around Baba Yaga, which calls some of the events into question. While a majority of it can be explained by [[spoiler: hallucinogenic pollen]], there's a particular sequence when Lara gets lost in a wooded area; when you return to it later, it is a much smaller area, and impossible to get lost in.

[[folder:Visual Novels]]
* The entire premise of ''VisualNovel/UminekoWhenTheyCry'' is based on this, so much that the creators have established two distinct camps where the fans can take sides. There's Fantasy, for those who favor the idea that everything was done by witches and magic, and Mystery, which believes that everything was done by human hands, and that witches were no way involved. This becomes increasingly difficult, as more than a few EpilepticTrees are bound to pop up in order to explain everything done by human means. Now, that's the simple part, but with Anti-Mystery and Anti-Fantasy mixed in, everything gets a whole lot weirder. [[spoiler:While it's never outright stated whether everything is magic or mundane, there are hints in the second half of the series that make it lean more towards the mundane side. This includes the fact that three characters are actually the same person, and how it's implied that this person created many of the magical beings as [[ImaginaryFriend Imaginary Friends.]]]] There's also the fact that, while Beatrice spent the first half of the series trying to get Battler to submit to her and be convinced that the murders were done by magic, [[spoiler:[=EP5=] reveals that she doesn't want to win at all, but to make Battler win.]]
* ''[[VisualNovel/HigurashiWhenTheyCry Higurashi]]'' does this too; the "[[AnimatedActors Wrap Party]]" at the end of the first novel has all the characters arguing about whether the events were due to humans or a curse. Amusingly, Ooishi takes the side opposite what he does in the novel, and Keiichi doesn't care, since they're all trying to get him anyway. However, it's resolved eventually: [[spoiler:It's mostly mundane, with the weirdness being a combination of a GovernmentConspiracy and HatePlague; however, the repeated arcs are due to magic, and [[GroundhogDayLoop Rika remembers all of them.]] In other words, there ''is'' "magic" at work, but the murder mystery is 100% mundane and magic is only used to "explore" it.]]
* In ''VisualNovel/{{AIR}}'', Kano may or may not be [[SpeaksFluentAnimal able to talk to animals]].
* ''VisualNovel/HatofulBoyfriend'' has Anghel, who is always off in his own bizarre fantasy world and claims to be the reincarnation of a fallen angel. Time spent around others tends to draw them into it and they speak in the same overwrought, PurpleProse-y way he does, about gods and demons and fantastic things. The end of his route in the first game involves confronting the ObviouslyEvil Shuu, who there refers to himself as Dark Sorcerer Wallenstein and summons Himnesia, Bringer of Death. When Himnesia is defeated Shuu retreats and is never seen at the school again. ''Bad Boys' Love'' has a report saying that he secretes hallucinatory pheromones, which he's not immune to, and acts as a neurotransmitter, so he's kind of sucking other characters into his own constant trips... This is an odd sort of mundane, but it seems semi-plausible. Except that Anghel often knows things he should have ''no way'' of knowing about - the weird names he uses for people, if translated, often tie in to secrets they hold, and he seems to have a sense for diseases.
** In ''Holiday Star'' a villain draws blood from him and uses it to take the power of otaku fantasies and convert it into a from which powers a DeathRay - and the ray is countered by Anghel and some others taking on a fantasy that they are {{Magical Girl}}s and using their magic powers to shield. He may be a RealityWarper.

[[folder:Web Comics]]
* ''Webcomic/{{Fans}}'' is certainly not "mundane" in all respects, but in a sequence where Guth visits his cousin in the afterlife, one of the first things he does is explain why it ''can't'' be a dream (arguing that it's a LotusEaterMachine), but when he wakes up in his chair, he promptly takes it as one rather than accept the idea of life after death.
* ''Webcomic/BobAndGeorge'': [[http://www.bobandgeorge.com/archives/010122 So to speak.]]
-->'''George''': ''But you were a ghost! And you yelled at me!''
-->'''Mega Man''': ''I assure you there's a rational explanation for all of that. I just don't have it.''
* In ''Webcomic/SomethingPositive,'' WordOfGod says he doesn't know for himself whether Fluffmodeus is [[NotSoImaginaryFriend real]] [[ImaginaryFriend or not]]. Nobody but Kharisma can see him, but ''someone'' put that other inmate into a coma...
* Parodied at the end of the ''Avatar'' episode of ''Webcomic/MonsterOfTheWeek''. Mulder and Scully argue about old lady that was haunting Skinner in this episode:
-->'''Mulder:''' ''I think she was the ghosts of Vietnam.''
-->'''Scully:''' ''I think she was Mulder's mum.''
* Peter, the enemy of the AffablyEvil title character in ''Webcomic/{{Niels}}'', is regularly visited by and engages in not-always-consensual-on-Peter's-part relations with a demon only he can see. No proof as of yet whether it's real or a product of all the drugs Peter's on.
** Although the demon in question ended up amusing his [[Creator/{{Humon}} creator]] so much she gave him [[Webcomic/ManalaNextDoor his own series]].
* ''Webcomic/QuestionableContent'' managed to pull this off in strip 546, [[http://www.questionablecontent.net/view.php?comic=546 "Arbitrarily Named Comic Strip."]] Did Hannelore's little voodoo doll of Marten actually work? Or did Dora just grab Marten's butt? We shall never know.
* Mary/''Christ''ina from ''Webcomic/TheAdventuresOfDrMcNinja'' had the ability to perform spells at random to help save the world, but every one of her miracle spells left open the possibility that they had happened by chance.
* WordOfGod is that ''Webcomic/{{Dissonance}}'' will go this route--there will be a "scientific" interpretation and a "religious" interpretation, and both will be equally valid.
* In ''Webcomic/FauxPas'', the rabbit Stu belonged to a stage magician. [[http://www.ozfoxes.net/cgi/pl-fp1.cgi?585 How much of it is stage magic is up in the air.]]
* While the existence of magic is an established part of the setting in ''Webcomic/ElGoonishShive'', the existence of the divine is kept far more ambiguous. In particular, a certain type of spell, known as a "guardian form" is speculated in-universe to be divine in origin. On the one hand, Nanase was praying at the moment she acquired hers, and it does turn her into an angel, making the possibility of divine intervention sound more likely. On the other, it was well within the established rules of the setting for her to gain that spell at that moment, so it may have just been perfectly ordinary magic.
* In ''Webcomic/TheOrderOfTheStick'', the deceased [[BigGood Lord Shojo]] appears to [[TokenEvilTeammate Belkar]] when the halfling falls into a coma, as a result of triggering his [[RestrainingBolt Mark of Justice]]. Shojo says he could be either the real deal's spirit, appearing to Belkar from beyond the grave, a personification of the Mark of Justice (which makes sense since when it was first activated it also produced an image of Shojo), or simply a fever-induced hallucination.
* The Toughs from ''Webcomic/SchlockMercenary'' get the deal they do on the PDCL due to strange voices convincing Petey the ship is haunted, driving him insane. Fixing the ship's plumbing fixes the issue, but due to the specificity of the utterances, Petey finds this explanation so untenable that only enforced cognitive dissonance can keep him from committing suicide.
* Much of the mystery in ''Webcomic/{{Freakwatch}}'' is built around this trope. If Uncle Ted only died of a heart attack, [[TheCoronerDothProtestTooMuch why was he holding a gun when he died?]] [[CorruptHick And why does the mayor want the investigation into his death closed?]] And if Jessica's dreams are only dreams, [[UnreliableNarrator why does she start seeing them in the daytime?]]
* Discussed in ''Webcomic/{{Blindsprings}}''. After the Academists' rebellion, the population suffered a plague that Orphics took as a sign of the spirit's wrath, but the Academists dismissed as poor hygiene conditions.
* In ''Webcomic/{{Shortpacked}}'', the historical Jesus Christ begins working at the store [[spoiler:after Galasso resurrects him]]. Mike tries to ask him what he really thought about himself and his relationship to God, pointing out that [[{{Jerkass}} no matter the answer, it will piss off somebody]]. Before Jesus can answer, he's tackled by Mike's wife.
-->'''Amber:''' ''Ohmygod, I just tackled Jesus''.\\
'''Mike:''' Maybe.
* ''Webcomic/WilfredaTheWannaBeWitch'': The title character claims to be a witch but many of her classmates just think going overboard playing make believe. That is until they find out her mother owns a candy shop and her birthday is on Oct 31. Then some doubt starts to creep in. Summed up nicely when Victor, one of Wilfreda's more skeptical classmates, asks her mom about that.
--> '''Victor''': This is all coincidence right? I mean...Wilfreda is not a real witch...is she?
--> '''Wilfreda's Mother''': ''(Smiling wryly)'' I'll have the delight of leaving you guessing. Happy Halloween!
* ''WebComic/StandStillStaySilent'' went through a period of this while introducing its most fantastical elements. The story starts out as a fairly standard JustBeforeTheEnd plot with a quickly spreading disease, set in modern-day northern Europe. Then, at the very end of the prologue, an EncyclopediaExposita page from AfterTheEnd casually mentions Finland having many mages. Chapter 1 introduces a couple of characters as mages, but doesn't show them do anything special. It takes Chapter 3 to see something that ''may'' be magical happen, with the following chapters showing stuff that becomes less and less likely to happen by mundane means, eventually lifting all doubt about the fact that TheMagicComesBack actually did happen. And once that is settled, the nature of the disease that caused TheEndOfTheWorldAsWeKnowIt and its horribly mutated victims starts falling into this trope. It is also unclear whether TheOldGods have something to do with TheMagicComesBack or the disease, or if it is just the best explanation people could come up with. All we know is that the two surviving nations that haven't gone back to worshipping them are completely devoid of mages (and WordOfGod points to gods being involved at least for Icelandic mages).

[[folder:Web Original]]
* ''WebOriginal/VoxAndKingBeau'' starts off this way, with Vox not sure if anything she's seeing and hearing (strange stifling silences, whispered voices in her ear, and her childhood best friend standing over her bed at night) is actually happening or if she's just hallucinating it. The end of the story seems to support the "magic" theory, as Vox continues to see and hear things [[spoiler:even after the removal of her brain tumor]] and people around her begin to notice the mysterious events, too.
* In the ''[[VideoGame/ChoiceOfGames Choice of the Vampire]]'' web game, a priest brandishes a crucifix at the main character, who is weakened and repelled -- unless they're an atheist. Whether a religious vampire is defeated by the [[ClapYourHandsIfYouBelieve placebo effect]] or a skeptical vampire's own convictions let them FightOffTheKryptonite is ambiguous, and the vampire community treats the matter with some caution as a result.

[[folder:Western Animation]]
* Succinctly summarized by the God-entity in ''WesternAnimation/{{Futurama}}'' (who is in himself an example - the most description given was that being "the remains of a space probe that collided with God" "seems probable"):
--> "When you do things right, people won't be sure you've done anything at all."
* ''WesternAnimation/KingOfTheHill'': Did the TV remote that helped Peggy change the channel to convince Hank to be on Luane's Manger Babies show contain batteries [[DivineIntervention or not]]?
* On ''WesternAnimation/TheSimpsons'', after a CoincidentalBroadcast:
-->'''Homer:''' Good thing you turned on that TV, Lisa.
-->'''Lisa:''' I didn't turn it on, I thought you turned it on.
-->'''Homer:''' Oh, well, turn it off anyway.
-->'''Lisa:''' ...It ''is'' off.
* In the ''WesternAnimation/SouthPark'' episode "Cartman's Incredible Gift" the police believe Cartman is a psychic. Kyle points out at the end that no one is psychic and there is a logical explanation for everything that is supposedly supernatural. However, when Cartman and a group of other psychics engage in a psychic battle, with a lot of wild hand gestures and odd vocalizations, Kyle gets extremely fed up and screams at them to stop. As he yells, the lightbulbs shatter and the shelf above his bed breaks. After a {{beat}}, Kyle says there is a logical explanation for that, too.
** Mr. Hanky the Christmas Poo is this. He initially looks like an ordinary piece of poo to most people, which gets the boys in a lot of trouble at first, but he moves and talks to the boys in private. The ending confirmed him as definitely magic when he showed up in front of everyone for a speech.
** Is Mr. Hat a living and sentient being or is he just a mere hand puppet?
* The end of every episode of ''WesternAnimation/MonaTheVampire'' would end with both a logical explanation for what happened, but also hinting that something magical did occur. For example, an episode where a T-Rex came to life ended with Mona revealing a fresh dinosaur footprint in the soil.
* Very common in the episodes of ''WesternAnimation/HeyArnold'' where the kids investigate the city's urban legends; usually, the episode will end with them discovering what ''seems'' to be a logical explanation for the myth (for example, the mysterious train that supposedly delivers people to [[{{Hell}} the Underworld]] was actually just going to a steel mill), only for... something... to happen in the last few seconds, visible only to the viewer and not to any characters in-universe, that casts doubt on a purely mundane interpretation.
* ''WesternAnimation/MyLittlePonyFriendshipIsMagic''
** The episode "Hearth's Warming Eve" features creatures known as Windigos--horses that spread ice and wind and snow wherever there's hatred. At the very end, the Mane Six get in a brief argument while a snowstorm rages on outside. They stop upon hearing the sound of wind, which is eerily similar to the sound of the Windigos...
** Considering the [[MundaneFantastic state of the universe]] the show is set in, the Magic part is very well an option.
** Zecora plays this trope straight in ''Magic Duel'' where she refills a mug of tea by waving her hoof over it. Was it sleight of hand (er, ''hoof'') and a subtle foreshadowing of Twilight's use of stage-magic to take down Trixie, or was it genuine magic which, according to the show's MagicAIsMagicA principle shouldn't be possible?
** Season 5 has the [[MagneticPlotDevice Friendship Map]], which has a knack for calling just the right members of the Mane 6 for each friendship crisis it detects...which is all well and good, but when it calls Rarity and Applejack to handle a crisis in Manehattan, it sets up an unusual opportunity for Big Macintosh to bond with Apple Bloom at the Sisterhooves Social. Whether this was just convenient timing or carefully orchestrated by the [[WorldTree Tree of Harmony]] (which is connected to the map) is anypony's guess.
%%* A few episodes in ''WesternAnimation/AvatarTheLastAirbender'' end this way, particularly ''The Fortune Teller'' and ''The Swamp''. Avatar uses basically every combination of mundane or magical explanation at some point.
* In Book 4 of ''WesternAnimation/TheLegendOfKorra'', after [[spoiler: Zaheer and the Red Lotus nearly killed her at the end of Book 3]], Korra starts having hallucinations of herself as she was during her fight with Zaheer in the Avatar state. At first it seems that Dark Avatar Korra is only a symptom of Korra's trauma, with [[ThroughTheEyesOfMadness one fight seen through both Korra's POV, where the vision is attacking her]] and a normal POV, which shows that Korra's opponent is actually a female earthbender. But Korra later comes across a small spirit (in the form of a dog at the time), which reacts to Dark Avatar Korra and apparently scares her off, while Korra is sent flying by her attacks during their battle in the swamp. In the end Dark Avatar Korra's nature is LeftHanging, though one could possibly assume she was a manifestation of Korra's confidence issues that she needed to overcome.
* ''WesternAnimation/BatmanTheAnimatedSeries'':
** In the episode "Zatanna", it's clear, even to the point of being outright stated, that ComicBook/{{Zatanna}}'s tricks are just stage magic. If you read the comics however, you know that Zatanna is capable of real magic, and it's later confirmed on ''WesternAnimation/JusticeLeague''. There are a couple of incidents[[note]]the Joker card predicting young Bruce's future and Zatanna's final disappearance[[/note]] that raise the question of whether or not real magic was involved.
** The episode ''Read My Lips'' has Batman analyzing the Ventriloquist and Scarface's voices in the Batcomputer. The result shows that those voices belong to ''two different persons''. Batman also says to Alfred that he studied with the world greatest ventriloquist, Zatara (Zatanna's father) and that the Ventriloquist could ''give him lessons''. So, InUniverse, they aren't sure if the Ventriloquist is just way better artist that the world greatest magician, or if Scarface is truly a DemonicDummy. For what it's worth, the two actually were voiced by the same actor, so maybe the Batcomputer just wasn't up to snuff.
** In ''The New Batman Adventures'', Scarecrow went through a major design overhaul because the crew felt that he didn't look scary enough. The redesign is far more undead, featuring the character looking more like a priest in a wide-brimmed hat with a noose around his neck, long hair, and the face looks along the lines of a skeleton. [[WordOfGod The creators]] indicated that they weren't even sure if the character was human anymore, and whether or not it's just a costume.
** Also ''[[WesternAnimation/BatmanMaskOfThePhantasm Mask of the Phantasm]]'', wherein it's left ambiguous as to whether the Phantasm has supernatural abilities or simply uses smoke grenades and other tricks.
* Used in ''WesternAnimation/YoungJustice'' with Holling Longshadow. When talking with Jaime about his grandson Tye's disappearance, he gives Jaime some advice that sounds like nonsense at first. As the show unfolds, however, it turns out to be {{Foreshadowing}}. Here's the conversation, with the double meanings in asterisks.
--> '''Longshadow''': He won't be back for a few weeks[[note]]he is eventually returned safe and sound a few weeks later[[/note]]. He's begun a quest of awakening[[note]]his metagene gets activated by the Reach[[/note]] that will link him to his heritage [[note]]the gene[[/note]] and show him the path to his destiny [[note]]he gets superpowers[[/note]]. Maurice is just a distraction [[note]] Tye's mother's boyfriend, hinted to be abusive towards Tye, and who Jaime thinks is responsible. He has nothing to do with it[[/note]]. He plays no part in Tye's vision quest, or in yours.
--> '''Jaime''': Mine?
--> '''Longshadow''': You search for answers, but the answers you seek will find you [[note]]Impulse arrives the next episode looking for Blue Beetle in order to tell him about the Scarab[[/note]]. Only then will you make peace with the one inside you [[note]]the Scarab, the A.I. in Jaime's spine he has trouble controlling[[/note]].
* Used in a few episodes of ''WesternAnimation/{{Doug}}'':
** In "Doug's Lucky Hat", the title object lands at Doug's feet on a windy day, and when he puts it on, he becomes a good luck magnet. He wonders aloud to Porkchop if the hat really is lucky, as Skeeter believes, or if it just seems to be lucky because he thinks it is, but he is evidently slightly embarrassed by his belief in the hat's power, as he tries to avoid admitting the truth to Patti when she asks him why he never removes the hat. When Roger "borrows" the hat to improve his chances of passing his biology test (which he does), leaving Doug feeling lost, Patti convinces him he is a winner with or without the hat. Whether or not the hat really brings its wearer luck is left to the viewer to decide.
** In the Halloween episode, Doug and Skeeter are helped by a mysterious cloaked figure who seems to just be a costumed amusement park employee. However, at the end of the episode he claims to be "Baron Von Hecklehonker", a character in the framing story about Bloodstone Manor, right before disappearing into thin air.
* Plank from ''WesternAnimation/EdEddNEddy'' is either a board with a face drawn on it that Johnny goes through extreme lengths to support his imaginary friend, or an actual separate entity that really can talk only to Johnny.
** However, it seems that Plank might actually be its own entity after all, since in the ''WesternAnimation/EdEddNEddysBigPictureShow'' we can see him ''driving a bus''.
** One episode has [[CloudCuckooLander Ed]] concocting off a very bizarre scam, which turns out to be a curse from one of his comic books. [[AgentScully Edd]] tells him curses aren't real...then an awful amount of crows appear. When they swoop in on the Eds, [[NightmareFetishist Ed]] merrily cries out: "EVIL TIM HAS BECKONED THEM!" This statement is never proven true or false as the episode ends there.
* In the ''WesternAnimation/AllGrownUp'' episode "It's Cupid, Stupid" it was left ambiguous whether Lil' Q was really Cupid or it was just a coincidence that people were falling in love after getting hit by his hacky sack. The last person to be hit by the hacky sack, right at the end, didn't seem affected by it.
* ''[[WesternAnimation/{{Madeline}} Madeline's Christmas]]'' never outright states, but very strongly implies that kindly old Madame Marie is a disguised angel, who uses her powers to clean the kitchen, cure the girls and Miss Clavel of their colds with her special homemade porridge, and bring the girls' families to visit them on Christmas Day despite the heavy snow that should have kept them away. This is a change from the original book, where the character is a (male) Middle Eastern magician who sends the girls home to their families on flying carpets!
* There is evidence for either interpretation, but the possibility that the adventures Jason and Michelle have in ''WesternAnimation/ThreeTwoOnePenguins'' with their four penguin buddies Zidgel, Midgel, Fidgel, and Kevin could either be real adventures or just in their imagination was [[LampshadeHanging lampshaded]] from day one:
---> '''Jason''': (''to the penguins'') I can't believe you guys are alive!\\
'''Midgel''': Either that or you're daydreaming.
