->"''Think you of the fact that a deaf person cannot hear. What deafness then, might we not all possess? What senses might we lack that we cannot see and cannot hear a whole other world around us?''"
-->-- ''[[{{Literature/Dune}} The O.C. Bible]]''

There are just some things that [[{{Muggles}} normal people]] don't seem to notice. In some settings it's because they just [[WeirdnessCensor don't seem to want to see it]]. In some it's because it's [[BystanderSyndrome just not their problem]]. But then there are the settings where they don't notice because they literally '''can't''': The supernatural creatures just can't be seen in the first place without having some supernatural power of your own. Whether it's psychics being able to see ghosts or wizards being able to see magical creatures, the one thing that stays the same is that the normal people just can't see what's really going on.

Sometimes this is accomplished by innate ability, or sometimes it's a spell that keeps them hidden. Sometimes it's because they just [[PhantomZone aren't in phase with the rest of the world]], but the end result is the same.

This trope can often aid the {{Masquerade}}.

When it goes down, expect someone thus hidden to ask "YouCanSeeMe"

See also BlindSeer, PlausibleDeniability, NoBigDeal, BystanderSyndrome, UnusuallyUninterestingSight, and WeirdnessCensor (which are the standard explanations to why this works). This trope is a subtrope of ByTheEyesOfTheBlind, and sister trope to InvisibleToAdults. If the invisibles are [[OurGhostsAreDifferent ghosts or similar undead figures]], you get ISeeDeadPeople. Compare CityOfWeirdos.

[[folder:Anime & Manga]]
* In the ''VisualNovel/ElevenEyes'' anime only the fragments can see the black moon.
* A few smaller examples are abound in ''Webcomic/AxisPowersHetalia''. There's all of England's "magical friends" (Unicorn, Flying Mint Bunny, Brownie, and an assortment of fairies and other magical creatures) of which only he can see (and a few select others such as Norway and on occasion France, though only when in England). Then Japan's Kappa, which only England can see as of the present, and presumably Norway's Troll. Though it's been said that everyone (but America, except for on Halloween) can occasionally inherit England's second sight when visiting the nation, England and Norway are the only ones with the ability to see the magical creatures which are invisible to normal people.
** ''World☆Stars'' revealed that Iceland can see magical creatures as well, though in the interest of appearing as [[IJustWantToBeNormal normal as possible]], he pretends that he can't.
* During ''[[{{LightNovel/Bakemonogatari}} Bakemonogatari]]'''s ''Mayoi Snail'' chapter, Koyomi is the only person who is actually seeing and interacting with Mayoi. Hitagi understands that something odd is happening as she watches Koyomi interact with Mayoi but tries to play the situation by ear. It takes her most of that arc to admit to Koyomi that she can't see the other girl. Mayoi is currently an apparition that gets attached to people who possess an urge not to go home.
** The audience is actually given a decoy scene earlier when Hanekawa interacts properly with Mayoi (though the latter is uncomfortable around Hanekawa).
* In ''Manga/{{Berserk}}'', normal people, especially those who are dedicated to the Holy See's religion and those who have never had a supernatural encounter, can't see elves. As Puck attempts to explain, when a person looks at something, they imprint the event in their memory and they remember it, but if they don't remember what they've just seen, [[WeirdnessCensor then they only try to remember the good parts of that event.]] A simpler explanation would be that when the secular religion took over the pagan beliefs, it all became a matter of [[ClapYourHandsIfYouBelieve clapping one's hand to believe]], and [[{{Muggles}} the populace]] only see stuff that they want to see.
* ''Manga/{{Bleach}}'': Spiritual beings such as ghosts, shinigami and hollows are invisible to normal humans but can interact with the world in ways that will be visible. Humans with spiritual power can see these beings but only a few have the power to fight spiritual threats, something at least one hollow has exploited.[[note]]The Grand Fisher uses a lure on his head disguised as a vulnerable female child. If anyone sees that child it gives them away as people who have spiritual power, making them [[IAmAHumanitarian good eatin']][[/note]] If humans lose their spiritual power they can no longer see the spiritual world. The sole exception is Uryuu, who mysteriously retained his ability to see the spiritual world despite losing his power.
* Demons in ''Manga/BlueExorcist'' can only be seen by other demons and people who have been hurt or tormented by demons.
* In Creator/{{CLAMP}}'s ''X'', the super-powered fighters have the ability to create "kekkai" which are barriers that prevent normals from entering, and repair all damage within them when dispelled. However, if the fighter is killed in the battle, the kekkai disappears and all damage immediately appears in the real world.
* In ''Manga/CardcaptorSakura'', there are some beings/objects/dimensions that can only be seen/experienced by people who have magic powers. However, Sakura's older brother, Touya, has the distinction of being the only one who can see ''ghosts''.
* In ''LightNovel/ACertainMagicalIndex'', magicians regularly lay down barrier spells/runes to prevent normal people from seeing them and what they do. One likens it to the world being a coin, where normal people are standing on one side and magicians are on the other. Most of the time, this effect is achieved with a spell that makes normal people simply leave the area.
* In ''Anime/DarkerThanBlack'', observer apparations are invisible to anyone who isn't a [[DifferentlyPoweredIndividual Contractor or Medium]]. This tidbit blows one Contractor's cover when one person notices that she's [[YouCanSeeMe staring at a puddle of water a little too intensely]].
* Shinigami in ''Manga/DeathNote'' can only be seen and heard by people who have touched a Death Note belonging to them.
* A variation on the trope. In the first ''[[Anime/ElHazardTheMagnificentWorld El-Hazard]]'' series, only Nanami Jinnai [[GlamourFailure can see through the Mazoku race's illusion]], a unique, personal power gained by crossing dimensions. However, she is unable to see the illusion ''at all'', so she doesn't ''know'' she's seeing through an illusion and [[IThoughtEveryoneCouldDoThat assumes what she sees is normal because nobody else comments on it...]]
* ''Anime/FutariWaPrettyCure'' takes this to extremes -- the girls' joint Transformation Sequence is a sound and light show on a par with an industrial accident in a fireworks factory, and no one but their current opponent ever notices it -- or their equally pyrotechnic attacks.
** The attacks are usually unseen because people faint or disappear when the bad guys arrive. The transformation itself is actually instant.
* In the anime (and part of the manga) ''Manga/{{Gantz}}'', during the "games" the main characters and their quarry are literally Invisible To Normals, though they still cause lots of inexplicable blood stains and property damage.
* Among the powers of Helen of ''Manga/HelenESP'' is the ability to see various otherwise hidden supernatural beings.
* In ''Manga/JoJosBizarreAdventure'' from the third arc onward, the metaphysical 'body' of a Stand is only visible to other Stand-users. This makes [[BadassNormal Hayato]] from the fourth arc a particularly impressive character in that he provides invaluable assistance to the heroes despite only being able to perceive Stands through their effects on the physical world.
** This becomes a minor plot point for Hol Horse when he tries to threaten some people with [[CoolGuns Emperor]] only to get pointed out that they can't see it.
** A recurring element throughout the series is someone who couldn't see Stands suddenly commenting on them. When this happens, it's a sure bet that they're due to develop a Stand of their own.
** For the sake of game balance, video game adaptations of the series have non-Stand users (like Speedwagon, Von Stroheim, Will & Caesar Zeppeli, Lisa Lisa, and the Pillar Men) who can still hold their own in a fight against Stands ([[VideoGame/JoJosBizarreAdventureEyesOfHeaven or tag team successfully with a Stand user]]), although it's never clarified whether they can actually ''see'' Stands or not.
* The characters in ''Manga/KamichamaKarin'' really are invisible when transformed.
* In ''Anime/KillLaKill'', Ryuko's superpowered uniform Senketsu is sentient, but normally, only she can hear his voice, leading the others to think he is her ImaginaryFriend or CompanionCube. At one point, Senketsu directly gives Tsumugu a threat and he's surprised to actually hear him. Ragyo and Satsuki can hear him as well.
* In ''VideoGame/KiniroNoCorda'', the protagonist Kahoko can see Lili, the fairy of her high school, which is something only a few can do. Lili was so happily surprised she gave Kahoko a [[ElegantClassicalMusician superpower]]...sort of.
* The manga ''Manga/{{Kuro}}'' provides us an inversion. At the age of six, children receive a shot that makes the monsters that threaten their town visible to them. The main character, Coco, was in an accident at that time and never received the shot when she was supposed to (and when it was effective). As a result, she's the only one oblivious to their presence.
* The Season Fairies in ''Anime/ALittleSnowFairySugar'' can only be seen at special times by special humans. In fact, [[spoiler:after the fairies find all their Twinkles, their human companions lose the ability to see them. This, of course, happens to Saga.]]
* Mages in ''Franchise/LyricalNanoha'' often put up a barrier that puts everything around them sightly out of phase/time to everyone else so they don't perceive the fights held between mages or the latest MonsterOfTheWeek. These barriers can, however, be breached and destroyed from the inside.
* ''Manga/MahouSenseiNegima'' explains that there are spells to prevent normal people from noticing magic and related phenomena. Normal people can still see magic, but they are predisposed to accept alternate explanations for it. This becomes a major plot point in an early-mid arc where someone wants to invert the spells, ''forcing'' people to believe in magic.
* ''Anime/MaiHiME'' mildly subverts this trope. While Yukino's power (usually) hides the various supernatural battles from the eyes of the normals, the collateral damage from those battles -- often quite significant in scope -- remains afterwards, to the concern and puzzlement of many.
** And in a further subversion, the damage gets bad enough that the normal students draw the conclusion that the Fuka-academy is too dangerous. Mai's non-hime friends are shown leaving and urge Mai to come along. The campus shuts down late in the series, soon after [[spoiler:Mai's UnstoppableRage over Takumi's death]] overloads Yukino's attempts to conceal the battle, but it reopens after the final battle, in time for the senior class to graduate.
** The Hime Star is invisible to virtually all non-Hime. Natsuki's mother tells her to never tell anyone that she can see it.
* ''Anime/MawaruPenguinDrum'' has the three [[EverythingsBetterWithPenguins penguins]] following the Takakura siblings around.
* The ''mushi'' of ''Manga/{{Mushishi}}'' can only be seen by certain people.
* Ecchan in ''Manga/MythicalDetectiveLokiRagnarok''.
* This trope forms the main premise of ''Manga/NatsumesBookOfFriends'': Natsume, the titular character, is forced to deal with several supernatural creatures that only he able to see which causes him a lot of grief, eventually turning him into a [[OrphansOrdeal very]] [[NoSocialSkills lonely]] [[FriendlessBackground person]].
* The main character in ''Manga/{{Noragami}}'' can only be seen by the main heroine, who saves him from getting hit by a bus. When she recovers, the people who were at the accident remark that there was nobody there besides her.
** [[TheProtagonist Yato]] later mentioned that it isn't like he is invisible but he is hard to notice like noticing exactly how many waiters are in a restaurant.
* ''Anime/PuellaMagiMadokaMagica'': Neither [[WeaselMascot Kyuubey]] nor the [[MonsterOfTheWeek witches]] (or the witches' familiars) can be seen by normal people.
* Ghosts in ''Manga/{{Rinne}}'' are invisible and intangible, and the hero has a coat that can do the same to him. It has the opposite effect when you [[ReversePolarity turn it inside out]].
* ''Manga/RozenMaiden''. In season one, Jun goes researching Rozen Maidens on the internet, only to find that nobody believes they exist. Yet, Sugintou goes flying in broad daylight in a busy city and nobody notices her. The dolls travel from place to place in flying doll cases- again in broad daylight. Logically speaking, SOMEBODY would have to notice the aforementioned occurrences. Yet, the only people who actually know about the dolls are the mediums/others they live with.
* In ''Manga/SgtFrog'', the aliens and their machines really are invisible, most of the time, thanks to their "Anti-Barrier". That, or they're in a laughably bad disguise that usually reveals their frog-like heads, much like Pinky And The Brain's Man Suit.
* The spirits in ''Manga/ShamanKing'' can only be seen by those with an affinity for them.
* Ghosts in ''Manga/{{Skyhigh}}''.
* In ''Manga/SugarSugarRune'', only witches and wizards can see magic spells being cast. Everyone else is "frozen" until the incantation is complete.
* The youkai in ''Manga/{{Tactics}}''.
* Much of what the runaway spirits in ''Manga/TheWorldGodOnlyKnows'' do can't be seen by people who aren't either supernatural themselves or linked to it by being a buddy or host. Other things aren't this convenient and do have to be hidden somehow. [[spoiler:Causes a real problem at the end of the Hinoki arc when Fiore more or less toggles the invisible off in regards to Hinoki's giant form and causes an event so large that Hell can't entirely cover it up and instead have to turn it into an urban legend that simply has no physical proof.]]
* In ''Manga/XxxHOLiC'', many of the weird spirits and occurrences that happen can only be seen by Watanuki, Yuko, and other spirits or supernatural beings. [[spoiler: Doumeki also eventually gains this ability after he gives half of his eye to Watanuki.]]
** Kohane who is introduced later in the series, like Watanuki, was born with this power.
* In ''Anime/YuGiOhGX'', Duel Monster Spirits are invisible to most people. What determines who can see them isn't really ever explained, and only a few individuals are even confirmed to be able to see them. Judai, Hayato, Johan, Manjoume, Fujiwara, Edo, Satou, and Geise could all see spirits, though Hayato, Satou, and Giese were implied to only see their own personal ones, and Edo said he could see strange things after his third duel against Judai.
* In ''Anime/YuGiOh5Ds'', Nicolas, Hermann, Hans of Team Catastrophe cheat in their duels by having the LivingShadow of their Hidden Knight - Hook attack their opponent's wheels to make them crash their motorcycles. Until they are beaten by the heroes, they are able to get away with this several times because ordinary people cannot see the shadow, so they think it was a regular accident. During Crow's duel with them, he is forced to dodge the shadow several times, and most of the audience is wondering what in the world he is doing. Carly is able to see the shadow and points it out, while Stephanie, who was sitting right next to her, doesn't see what she is pointing at.
* In ''Manga/YuYuHakusho'', most demon bugs and some demons can only be seen by people with high enough spiritual sense. Koenma uses this as an advantage to give out information to his detective and friends without the fear that muggles might see.

* In ''ComicBook/{{Fables}}'', there's an outright ''war'' on the streets of New York between the forces of the Adversary and Fabletown. They explain that there are many magical protections to keep "mundies" out of Fabletown (or just walk through, in cases of days where there isn't a gigantic battle) but the spells had to be weakened in order to cast another spell: a rainstorm to put out the fires. It's then noted that the rain will keep people out of their business and reduce visibility enough that, if they can finish the battle fast enough, nobody will notice anyway.
* In ''ComicBook/MonsterAllergy'', monsters can be only seen by people who have the Sight Dom. Tamers and Keepers are those people who can see monsters.
* In ''ComicBook/UltimateFantasticFour'', the Argiopes are spider-like [[ClockRoaches creatures who attack the sources of time paradoxes]] to protect the timestream, and can only be seen by time travelers.
* ComicBook/{{Zatanna}} once asked for {{Superman}}'s assistance against a portal that was spewing out demons. While Supes could see and fight the demons, he couldn't see the portal, even after going through all his different vision modes. Zatanna goes, "It's outside the electromagnetic spectrum!" and uses a spell to make it visible.
* One [[FlipFlopOfGod possible interpretation]] of Hobbes from ''ComicStrip/CalvinAndHobbes''.
* [[DontFearTheReaper Bernie]] of ''ComicBook/DeathVigil'' can only be seen by necromancers and other members of the Vigil. In one issue of the comic, Marlene explains to Clara that she's trying to capture her image on camera.
* In ''[[ComicBook/AthenaVoltaire Athena Voltaire and the Brotherhood of Shambalha]]'', Athena and Desmond both go into the temple of the Brotherhood of Shambalha, but only Athena sees anything there (and doesn't realise that Desmond ''isn't'' seeing anything — she only finds out later). Exactly why this is isn't stated, but it's probably a choice of the Brotherhood.
* The ComicBook/IncredibleHulk foe Mercy's whimsical explanation of her {{Invisibility}}.
--> '''Mercy:''' Give it up, Doctor. I can only be seen by people subjected to gamma rays. Or by people subjected to any intense radiation. Or by the nearly dead. Or those who are very sick. Or... anyone I feel like seeing me, really.
* ''ComicBook/{{Deadman}}'' is a ghost and cannot be visibly perceived by other human beings. This is an automatic ability, and one that Deadman has no control over. Beings gifted with supernatural prowess, may be able to see Deadman's true form.

[[folder:Fan Fiction]]
* In ''Fanfic/TheBestSevenYears'', Hobbes is a Furry. Furries are magical versions of regular animals born from said regular animals. They possess the traits of the animal they are, along with human traits such as speech and walking on two legs. Furries, however, can only be seen by wizards: Muggles see Furries are regular animals, or in some cases (Like Hobbes) as an inanimate version of that animal.
* ''Fanfic/HarryPotterAndTheMethodsOfRationality''. Harry, using the full power of whatever canon magic there is, gets a trunk shaped like an animated dragon whose magical powers are so high that muggles can't see it.
* In ''I.D.: That Indestructible Something'', many individuals across the world get transformed into creatures from fantasy works (such as ''WesternAnimation/MyLittlePonyFriendshipIsMagic'') or myth. While they can see each other's true forms, all the "normal" people still see them as ordinary humans. They don't notice any inconsistencies either, such as the fact that they need to bend down to touch the apparently six-foot-tall person, who's in actuality a pony half that size. However, this effect has limitations and stops working if someone's confronted with too much weirdness at once (such as encountering an elephant-sized dragon.)

* In the James Stewart movie ''Theatre/{{Harvey}}'', Harvey is a pooka, a fairy spirit who appears to Stewart's character as a six-foot white rabbit, but who is invisible to others. Naturally, everyone else thinks Stewart is insane. It's not explained what causes only Stewart's character and later the shrink to see Harvey.
* In the ''Mostly Ghostly'' film series, Max can see Nicky and Tara but the others don't see them because they are both ghosts.
* In the 1997 film, ''The 6th Man'', after Kenny's brother, Antoine dies, Kenny can see Antoine but the others don't see them because Antoine is a ghost.
* Nick in ''Film/TheInvisible'' can only (barely, sometimes) be heard and felt by the girl who has almost killed him. And by animals. To everyone else he is invisible.
* In ''Film/OhGod'', God cannot be seen, heard, or recorded by humans unless He allows it. This even extends to transcripts, such as a stenotype paper record of His courtroom testimony.
* In ''Film/{{Beetlejuice}}'', ghosts typically cannot be seen by mortals because they instinctively ignore the strange and unusual. However, the {{Goth}} girl Lydia can because she is, in her own words, "strange and unusual".
* In ''Film/TheSorcerersApprentice'', magic itself is invisible to normals, as demonstrated by Becky's inability to see a giant flaming pentagram above the city. Magic that creates physical effects, such as starting a fire or animating a statue, is visible, since the objects themselves are otherwise normal.
* In ''Film/DragonballEvolution'', normal humans cannot see ki attacks.
* In ''WesternAnimation/{{Paranorman}}'', no one believed that ghosts and Norman's power to see ghosts are real because ghosts are invisible to humans, except for Norman and Neil.
* In ''WesternAnimation/{{Coco}}'', only the dead are able to see other spirits, being completely invisible to the friends and family they come to visit on Diá de los Muertos. The exception to this rule are animals like Dante, as well as ''alebrije'', guardian spirits, that can travel and live in both the Land of the Living and the Land of the Dead. [[spoiler:Pepita, Mama Imelda's massive winged jaguar, is a simple tabby cat in the Land of the Living.]]
* In ''Film/TheFrighteners'', a woman is being frightened by flying babies, in which [[spoiler:it was just Stuart and Cyrus that are carrying the babies]]. She didn't seem to see and hear the ghosts.

* In Icelandic folklore the Hidden People are a race of people that are invisible to humans, unless they wish to be seen. Oddly enough, they would also be invisible to one another if it were not for a salve that is smeared in the eyes of their newborns. Normal humans only know this because the Hidden People tend to lack midwives, and thus seek humans' help when in labour. The human midwife would then be asked to smear the salve in the infant's eyes, and would then accidentally get some of the salve in one of her own eyes. From then on she would then be able to see the Hidden People and their world with one eye. Often resulted in madness...
** Similar stories about midwives to TheFairFolk often end with the Folk [[EyeScream making sure the midwife won't see them anymore.]]
* In the fairy tale "Literature/GodfatherDeath", Death gives his physician godson the ability to see him (Death) standing at the sick person's bed whenever he (the physician) is called, indicating to him whether the patient can be cured or is certain to die. No one else is able to see Death.

* In ''Literature/DragonBones'' GeniusLoci[=/=]FriendlyGhost Oreg invokes this. He can hide himself from everyone but his current master (the one who wears a ring that is given from father to firstborn son on the death of the father), but shows himself to Ciarra, the mute daughter of the house, presumably because she won't be able to tell anyone about him. That he is fond of her may have something to do with it, too. He is able to show himself to everyone else if he wants to, as shown later when he and Ward pretend that he's one of the many bastard sons of Ward's father.
* ''Literature/HarryPotter'' mentions that [[TheHeartless Dementors]] cannot be seen by Muggles, though they still feel the EmotionEater aura. It's unknown if anything else is like this.
** Played with a bit in regards to most magical locations. To keep Muggles from discovering magic, most wizarding locale use some sort of enchantment to keep Muggles from wandering into them, which includes spells to make them look like something else entirely (for instance Hogwarts, which will look like withered ruins to any Muggles that find it), repel them from the areas in question (the Quidditch World Cup's stadium), or to [[PerceptionFilter keep them from noticing the spot at all]] (The Leaky Cauldron). There are also things that even most wizards can't see, such as thestrals (horse-like reptilian beings that are invisible unless you've seen someone die) and any location protected by the Fidelius Charm (which keeps you from seeing a particular location unless you've been told the address by the Secret Keeper).
* ''Fablehaven'' has certain creatures that only those that are "fairystuck/fairykind" or "shadow charmers" can see,one jarring instance was a kobold who disguised himself as a cute guy and dated all the girls in Kendra's class despite being a goblin with pus leaking out the side of his head
* In ''Literature/LifeTheUniverseAndEverything'', a "Somebody Else's Problem Field" prevented anyone from paying attention to a spaceship present during a game of cricket.
* In the novel and miniseries ''Literature/{{Neverwhere}}'', people who live in the London Underground are effectively invisible to normal people. These people can stand in front of normal people, completely naked and actually trying to initiate some sort of conversation, and be utterly ignored. On the off chance they are able to grab someone's attention, they are almost always promptly forgotten. Played for laughs in one scene where museum security is called on to remove Richard, only to spend about half an hour trying to figure out just who they're supposed to arrest.
* In Terry Pratchett's ''Literature/{{Discworld}}'' novels, Death actually explains this. It isn't that the normals can't see them, it's that the normals' brains come to the logical conclusion that they CANNOT EXIST and therefore write them off as not existing. It's important to note that this only happens to adults. Children, who aren't educated and mature like adults, are imaginative enough to see what's really there. Wizards and Witches can also see them: both because they're magically attuned and because they're entitled to a personal visit when their time comes.
** Death's "granddaughter", Susan, inherits some of this talent in that she can make other people ignore her. When using it generally, she won't be noticed by normal people unless they focus their attention, but those of magical persuasion (like wizards) can still sense that someone's altering perception and use that to focus on her. However, once she knows someone's onto her, she can concentrate on that person, and even Archchancellor Ridcully can't pick her up once she knows he's trying to seek her.
* In ''Literature/TheMortalInstruments'', Shadowhunters, demons, and Downworlders are all invisible to normal people, or 'mundanes', until they've been bitten by a werewolf, forced to focus, or otherwise pulled in.
* In the ''Literature/PercyJacksonAndTheOlympians'' series, the Mist serves this function: it blurs Greek mythological elements to all mortals (except those with the unique ability to see through it) and replaces them with something they can understand (and less anachronistic). For instance, a sword might look like a shotgun, and a hellhound can run through Manhattan unnoticed because everyone thinks it's a truck. There are some mortals that can see through the Mist, but they are few and far between; hence, there is a good reason why it's impossible for us to find a way to the 600th floor of the Empire State Building, though it makes you [[FridgeLogic wonder how it can be]] HiddenInPlainSight [[FridgeLogic at the cruising altitude of airplanes]].
** The Mist can also be manipulated to make people think or see certain things. It can affect demigods, too: in ''Sea of Monsters'', when Tyson (a Cyclops) is outside Camp Half-Blood, Percy has to concentrate very hard or else it will appear to him that Tyson has two eyes instead of one.
** Deconstructed in the second volume: It turns out there's a second [[spoiler:Roman]] Camp Half-Blood, but because of the mist the campers don't ever remember them as what they really were: half-bloods. Then you realize that Percy and other half-bloods throughout history have fought and killed some VERY peculiar monsters who seemed... almost human...
* ''Literature/TheBartimaeusTrilogy'' by Jonathon Stroud takes place in an [[TheUnmasquedWorld Unmasqued World]], but this trope still applies somewhat: demons can change their forms and often do, though their true selves can be seen on "higher planes." Demons can see on multiple planes to recognize each other; magicians can use special contact lenses to see on a few and are thus harder (but not impossible) to trick.
* In ''Literature/KingdomKeepers'', the Overtakers can't be seen by anyone other than [[FiveManBand the DHIs]] at first. They eventually can be seen as [[ClapYourHandsIfYouBelieve more people believe in them]].
* In ''Literature/TheHeroesOfOlympus'' by Creator/RickRiordan, this is the entrance to Camp Jupiter and New Rome.
* In ''Literature/TwilightEyes'' by Creator/DeanKoontz, creatures called Goblins can only be seen in their true forms by humans with some psychic ability (the "Twilight Eyes" of the title). The main character has unusual purple eyes that make him able to see them. Another character has an amber third eye in his forehead with the same ability. The protagonist's love interest can also see their true form and see the future, though there doesn't seem to be any [[RedRightHand visual quirk]] to indicate it.
* Also by Creator/DeanKoontz, Literature/OddThomas sees a lot of things that are usually invisible. This is mostly a case of ISeeDeadPeople, but ''Deeply Odd'' has the Rhinestone Cowboy [[spoiler: and the rest of his cult]] who is normal person hidden by some dark magic. This is revealed when he threatens Odd with a gun in a busy grocery store. Odd assumes he's bluffing, as no reasonable person would draw attention to himself like that. Then he starts shooting, and all anyone else sees are his shots hitting a product display.
* According to the ''Franchise/StarWarsExpandedUniverse'', people who are not Force-sensitive cannot see or hear Force Ghosts. For example, during ''ComicBook/StarWarsLegacy'', Cade Skywalker is contacted by the Force Ghost of his ancestor, Luke Skywalker, but Cade's companions think he's talking to himself.
** It also happens in ''Literature/GalaxyOfFear: Ghost of the Jedi'', though initially even Tash can't see Aidan either, just sense that he's there and [[BeingWatched watching]]. She gradually becomes able to perceive him more and more clearly. When she's trying to enlist his help while being threatened, the BigBad says that [[TalkingToThemself acting crazy]] won't save her.
** In ''Junior Jedi Knights: Anakin's Quest'', Anakin Solo, Tahiri Veila, and Uldir Lochett enter the [[PsychologicalTormentZone Dagobah cave]]. While Anakin and Tahiri experienced horrifying visions, Uldir only perceived it as a cave, because he wasn't Force Sensitive.
* In ''Literature/SeptimusHeap'', the door to the Queen's Room is visible only to the Queens and Princesses.
* David Eddings' ''Literature/TheElenium'' and ''Literature/TheTamuli'' actually show three different ways to achieve the trope, each by a different supernatural force. Styric Child-Goddess Aphrael can cast a spell that makes people ignore her and anyone else with her. The Delphae Xanetia can alter the light around her, causing it to "wrap" around and pass her. And the the Troll-Gods somehow come up with a weird third way. In essence, they jump from one frozen moment to the next. To someone within, it looks like the world is going at something like 1 frame per second, with all the jerkiness that implies. Meanwhile, the rest of reality never gets to see the people inside because the instant they're visible is vanishingly small. Interestingly, due to the differing magics involved, method #3 seems to interfere with method #2 (someone in the skipping invisibility will see Xanetia with a multicolor glow).
* Inverted in "The Devil's Footprints" from ''[[Literature/PointHorror 13 More Tales of Horror]]''. Everyone at the party can see the mysterious goat costume guy, but [[spoiler:Brian the house-controlling computer cannot see him on the camera footage]].
* The 200 million horsemen army in the Literature/LeftBehind book ''Assassins'' is invisible to everybody but believers in Christ, but are nonetheless dangerous to those who aren't believers, as they have been unleashed to slay a third of the remaining world's population around the time of the Sixth Trumpet Judgment (believers not included).
* In Literature/JohnDiesAtTheEnd by Jason Pargin (a.k.a. David Wong) the majority of the monsters John and David battle are invisible to most humans. This is because [[spoiler:the monsters are from another dimension and their existence extends to this one by varying degrees. ]]Those that can see them are either psychic, not human, really drunk and stoned with an open mind, or in John's and Dave's cases have [[spoiler:taken the drug "Soy Sauce", which tunes your brain into the different "frequency" these monsters exist in]].
* Literature/{{Pact}} explains the lack of noticing Others by normal people as a result of the Standard of Suleiman bin Daoud (the Biblical King Solomon), an agreement that most Others, over the course of the past several thousand years, have been forced to sign by various practitioners that bound or negotiated with them. The Standard means that Others can't interfere with the uninitiated without some excuse-failing the test of a sphinx, or wandering where a goblin might find them instead of staying home.
* "Plateau Eyes" is the name of a mutation/psychic power in Creator/LarryNiven's ''Literature/KnownSpace'' setting. It keeps people from noticing/remembering you, and is explained as causing the muscles in someone else's eyes to contract, narrowing the pupil. When people are really interested in something their pupils get larger; the Plateau Eyes phenomenon inverts this twice: the widening is postulated to be the ''cause'' rather than the effect (or at least some kind of feedback loop), so naturally narrowing the pupils would make whatever the person is looking at seem singularly uninteresting. The first character known to have it (in ''Literature/AGiftFromEarth'') has been doing it subconsciously his entire life, often to his frustration (he'll be hitting it off with a woman, get nervous because he starts to think he might ''finally'' get to have sex, and then she stops talking to him and wanders away distractedly).
* In the ''Literature/ParadoxTrilogy'', plasmex is a type of psychic energy which few people can use, and even most of those who use it are incapable of seeing it. Phantoms, which are made completely of plasmex, are thus invisible to all but a few people.
* In the ''Literature/ElementalMasters'' series, only those with at least a touch of magic can see the [[ElementalEmbodiment Elementals]] (though they can see the effects of the elementals).
* In the ''Literature/TowersTrilogy'', magic spells are invisible to those who possess little magic of their own, but are visible as glowing lines of energy to people who possess it in greater amounts. Ghosts are invisible even to potent magic users, capable of being seen only by Xhea and each other.
* In ''[[Literature/DoNotTakeTheShells DO NOT TAKE THE SHELLS]]'', there's Harris's drawing of the EldritchAbomination. He perceives it as being disturbingly lifelike, but Cathy, who hasn't seen the real thing, can't see anything in the drawing at all.
* In ''Literature/TheGirlFromTheWell'', ghosts cannot be seen by ordinary people. They become visible to those they are targeting and those who have had past encounters with them, and can also be seen by the spiritually sensitive.
* In ''Literature/TheWhiteRabbitChronicles'', zombies can only be seen by a few people. Some of these people have the ability from birth while others gain it after a traumatic incident.
* ''Literature/TheStormlightArchive'': Some intelligent spren are invisible to anyone except [[BondCreatures the person they are bonded to]] (but can choose to be seen by others), while some are always visible. Non-intelligent spren are something else altogether; scenes from the point of view of someone who can SeeTheInvisible implies that spren are always around, invisible, but normally can only be seen when there is a strong source of emotion or natural phenomenon to feed off of.
* In ''Literature/TheSpiritThief'', regular people can't hear or talk to spirits, and even wizards - except for two very unusual ones - are incapable of actually seeing them. Though obviously, if a table stood up and started dancing, they'd notice.
* In ''Literature/TheMachineriesOfEmpire'', people who aren't hosts to the undead or undead themselves can't see or hear Jedao, which means that once Cheris leaves the facility where the black cradle is kept, she's the only person who can communicate with him (though he can hear and see everyone).
* ''LightNovel/TheUnexploredSummonBloodSign'':
** Summoners and vessels above a certain level gain a variant of this. A normal person can still see them just fine, but if the summoner or vessel leaves their field of vision, they lose all memories of them. It's speculated that this is because an uninitiated mind is unable to properly comprehend the supernatural. However, when the normal person sees the summoner or vessel again, they regain all memories of them.
** When a summoner and vessel actually summon, they gain another level of this. Electronic sensors, such as cameras and microphones, can no longer detect them.
* ''Literature/TheHeartsWeSold'' has a variant. Everyone can see demons just fine, but to most people, they appear as ordinary humans. Only people who are interested in [[DealWithTheDevil making a deal]] can recognize them for what they are.

[[folder:Live Action TV]]
* Throughout the seasons of ''Series/FraggleRock'' Gobo spends a lot of time ducking out of sight from the resident human, Doc... only to discover in the penultimate episode that under normal circumstances humans can't see Fraggles anyway, so he needn't have bothered. To add insult to injury, this is also the one episode where Gobo actually ''needs'' Doc to see him, so he has to work out how to make himself visible to the human. The "YouCanSeeMe" event happens in the last few minutes of the episode.
* The Last Great Time War in ''Series/DoctorWho'' is an example - in "The Unquiet Dead" it is stated that the War was invisible to lower races, but devastating to higher ones, particularly those who were time sensitive.
** The perception filter can also act like this; however, 'normal' means 'not in on the secret'. People won't be able to see that rather out-of-place Police Box unless they know to look for it.
** Weaponised in "The Sound of Drums" and "Last of the Time Lords", where the perception filter prevents anyone from noticing The Doctor, Martha and Jack during their attempt to hide from the Master, as well as allow Martha to organise LaResistance while the Doctor enacts his GambitPileup during "The Year That Never Was".
* Happens repeatedly to Annie the ghost in ''Series/{{Being Human|UK}}''. Most ghosts can only be seen by other supernatural creatures--for example, the new tenants of Annie's flat, a werewolf and a vampire. However, as time goes on, Annie begins to become more solid and visible, at one point able to pass as a living human again. During the transition, however, there's a lot of "Can you see me?", and George actually uses the phrases 'invisible to normals' at one point.
* ''Series/{{Supernatural}}'':
** At one point, Dean gains the ability to see those possessed by demons for what they are. This occurs when he is running out of time with his DealWithTheDevil.
** Hellhounds and Reapers are also invisible to normal humans, and can only be seen by the people they're coming after. Although in season eight, it turns out a normal person ''can'' see a hellhound, if they [[spoiler: look through glass that's been scorched with holy fire.]]
** While visible under normal circumstances, angels and high-level demons can makes themselves invisible ''and'' unheard by humans, allowing for an entire conversation to take place with an unwitting human ten feet away. Presumably other angels and high-level demons would be able to see them, and potentially humans with psychic abilities.
* Happens accidentally to Daniel in the episode 'Crystal Skull' of ''Series/StargateSG1''. This leads to a funny conversation between Daniel and his grandfather (who can see him due to having encountered the same phlebotinum skulls that turned Daniel invisible): neither realizes they're actually talking to each other at first, as his grandpa thinks Daniel is just a hallucination but talks back anyway, and Daniel doesn't expect an answer and is just responding to conversations to pass the time/rhetorically, as no one else can see or hear him.
** Also occurs in a number of other episodes, including one in which a young boy who arrives on base [[spoiler:is revealed to be able to see an invisible race, and was genetically created to have this ability]].
** There's also an episode where SG-1 activates an alien machine that allows people to see invisible creatures in another dimension (and forget how to use their brakes.) This understandably freaks-out the residents of Colorado Springs.
* ''Series/TheCollector'': Only [[DealWithTheDevil the Devil's clients]] can see and hear the temporary [[HellGate portals to Hell]] that appear to [[YourSoulIsMine collect]].
* As the OpeningNarration reminds us every episode, ''Series/QuantumLeap'''s Al exists as a hologram that only Sam Beckett can see, because he's being projected back in time [[MissionControl to guide Sam]]. A few episodes have children, animals, or mental patients seeing Al, and the YetAnotherChristmasCarol episode [[HandWave handwaves]] it by saying the Scrooge stand-in has brain chemistry similar to Sam's.
** That group of special individuals also includes some who [[GlamourFailure see Sam rather than the leapee]].
** In the episode which fans [[TheScottishTrope do not refer to by name]], an malevolent entity impersonates Al for most of the episode, then turns to acknowledge the ''real'' Al when he finally manages to show up. Sam and Al are naturally freaked out.
* In ''Series/TheAquabatsSuperShow'', Eaglebones Falconhawk's bird, The Dude, can only be seen by Eaglebones himself.
* In ''Series/HerculesTheLegendaryJourneys'', ''Series/YoungHercules'', and ''Series/XenaWarriorPrincess'', Gods cannot be seen or heard by ordinary humans unless they allow them to. Hercules can see them because he's a demigod.
* ''Series/{{Grimm}}'' has Wesen, supernatural creatures, whose true form is visible to Grimms when they are under stress or undergo other strong emotions. To everyone else, they appear human except in rare instances when they actually want to be seen, and even then [[YouCannotGraspTheTrueForm the person has a hard time processing it.]]
* ''{{Series/Extant}}'': The visions of dead people the astronauts see. Nobody else sees them and cameras or photos won't capture them, leading to questions of if it's just all in their heads. [[spoiler: Although later a "filter" enables film to show that at least something was present at the time.]]
* ''Series/BuffyTheVampireSlayer'' featured two variants of this in the fifth season.
** Most people just saw Dawn as a regular girl, but insane people and certain demons could recognize the energy construct she really was. Buffy's spell in "No Place Like Home" is a technical inversion, as it made Dawn invisible to the "abnormal" (magic-using) Buffy.
** When an ordinary human saw the transformation of [[spoiler:Ben into Glory or vice versa]], they would forget about it shortly after. Demons were not affected by this spell, but any attempts by Spike to explain this to the Scoobies were doomed from the start because the Scoobies would instantly forget what they had been told.
* Manny in ''Series/{{Constantine}}'' can choose who he's visible to, and often is only visible and audible to Constantine himself. Once, when they're talking while Zed is present, she asks where Manny is and Constantine delights in giving her the wrong directions so she ends up just wandering around the room.
* In ''Series/{{Shadowhunters}}'', the shadowhunters can make themselves invisible to [[{{Muggles}} mundanes]] with a special rune. Clary is able to see them because she's actually a shadowhunter too.
* In "The Children's Room", from the vintage anthology scifi series ''Tales Of Tomorrow'', only people with the right intellect-enhancing mutation can notice the titular room's presence in the library, or make sense of the writing in the books it contains.
* In ''Series/TheFlash2014'', Savitar is so insanely fast that his body is constantly vibrating. Only other people with SuperSpeed can see him, even if he's standing still.

[[folder:Tabletop Games]]
* Played with in ''TabletopGame/GeniusTheTransgression''. Ordinary people see [[WeirdScience Wonders]] just fine, and nothing prevents them from remembering what they've seen. When they start ''fiddling'' with the Wonders, however... [[GoneHorriblyWrong bad things happen]].
* ''TabletopGame/ChangelingTheLost'' has the Mask, a cover for all things fae. Changelings appear to be perfectly normal, despite being twisted (both [[BodyHorror physically]] and [[MindRape mentally]]) by their time in Arcadia, and [[TheFairFolk the True Fae]] can pass as well... [[GlamourFailure mostly]].
* ''TabletopGame/ChangelingTheDreaming'' has chimerical items and beings, creations and creatures of the Dreaming that can only be perceived by the fae or the people they enchant. In keeping with the game's themes, these things can affect you, but trying to affect them back - or even just taking the blow - can make you look nuts to mortal observers.
* In ''TabletopGame/MageTheAwakening'', High Speech -- the literal language of Awakened magic -- is inherently incompatible with {{muggles}} due to the Quiescence, a veil against the supernatural caused by the Abyss. As a result, ordinary humans cannot hear or read it; it just becomes vaguely foreign-accented gibberish on a casual scrutiny. On a deeper scrutiny, it acts as a BrownNote; they don't understand it, but it sparks off as so inherently ''wrong'' deep inside that they can be driven insane by exposure to it, which is one reason why mages try to not let muggles see or hear them using it.
* ''TabletopGame/VampireTheMasquerade'' and ''TabletopGame/VampireTheRequiem'' present the Obfuscate Discipline to vampires. Those with this ability can use it to conceal the presence of themselves or perhaps other things from the minds of mortals. The catch is that this is strictly a mental discipline, meaning nonliving eyes like cameras, beings with strong mental power, or beings gifted with SuperSenses (like those with the Auspex Discipline) can see through the concealment.

* The fairies in ''Theatre/AMidsummerNightsDream'' can be invisible to the humans. To avoid confusing the audience, Oberon conveniently [[BreakingTheFourthWall explains this to them.]]
* In ''Theatre/TheAddamsFamily'', the chorus of ancestral Addams ghosts can only be seen by the family. This leads to some amusing situations; for example, near the end Wednesday catches a bouquet thrown to her by a spectral bride, much to the confusion of her "normal" fiance.
* In ''Theatre/BlitheSpirit'', only Charles can see and converse with Elvira (the ghost of his dead wife).

[[folder:Video Games]]
* In ''VideoGame/SilentHill2'', the little girl Laura is the only one who doesn't see the monsters or how scary the town looks. This is actually a deconstruction of the trope specifically because she's normal, meaning she's the only one who's ''sane.''
* The ''VideOGame/{{Thief}}'' series strongly suggests that Keepers are Invisible to Normals when they want and only gifted people, such as Garrett, are able to notice them.
** Talented hiders would know where to look for the hiding places Keepers would use. This may overlap with InvisibleToAdults, as Garret was just a street urchin when he attempted pickpocketing a Keeper. This OriginStory is [[BookEnd bookended]] at the end of ''Thief 3'', when Garret, now the leader of the Keepers, catches a young girl pickpocketing him and gives the same line.
* In ''VideoGame/TheWorldEndsWithYou'', the Players of the Reaper's Game are invisible to [[spoiler:living people]], except when they go in shops to buy things. The Noise are also invisible. However, it is implied that there are some people who can see the Game, such as one bystander whose thoughts reveal that he can see Noise symbols. He calls them "weebers." Weebie weebie weebie... Another one mentions that she saw someone with wings.
* The ''VideoGame/TalesSeries'':
** In ''VideoGame/TalesOfSymphoniaDawnOfTheNewWorld'', Centurion Tenebrae is said to be this; naturally the party members of the previous game (and one notable exception), along with the protagonists can see him. However, only Colette and Yuan can see Tenebrae naturally. Tenebrae can turn himself visible, which lets the other party members interact with him.
** Seraphim in ''VideoGame/TalesOfZestiria'' cannot be seen by normal humans, as shown in some interactions between main protagonist Sorey and various human characters while the seraphim party members are with him.
* Shadow Pokémon in ''VideoGame/PokemonColosseum'' have a black, fiery aura that is invisible to everyone except the girl who, conveniently enough, is your traveling partner.
** In the sequel, the Aura Reader was designed as a means of detecting this aura for the more mundane protagonist - one of the obstacles for purification is the ability to identify Shadow Pokemon reliably and immediately.
** Throughout the franchise, Normal-type Pokémon are [[NoSell immune]] to Ghost-type moves and vice versa.
* ''Franchise/ShinMegamiTensei''
** The devils in ''Devil Summoner 2 - VideoGame/RaidouKuzunohaVsKingAbaddon'' certainly apply. Raidou can summon a devil to follow him around, and even send it out on solo missions, but most people are blissfully unaware.
** This was also true of the first ''Devil Summoner'' prequel, ''Devil Summoner: VideoGame/RaidouKuzunohaVSTheSoullessArmy''.
** Also applies to ''VideoGame/ShinMegamiTenseiStrangeJourney'', where demons are [[InvisibleMonsters invisible to everyone]] not looking out through a [[PoweredArmor Demonica]] equipped with the Demon Summoning Program.
* ''Franchise/TheLegendOfZelda'':
** In ''VideoGame/TheLegendOfZeldaOcarinaOfTime'', Link needs to uses the Lens of Truth later in the game to be able to see hidden doors, objects, monsters and a boss. One NPC in the game also claims it's possible to see such things by extensively training one's mind, but of course, doing this in the game isn't possible.
** In ''VideoGame/TheLegendOfZeldaSpiritTracks'', Zelda becomes a SpiritAdvisor and ExpositionFairy only [[TheHero Link]] and the Lokomo can see.
** In ''VideoGame/TheLegendOfZeldaBreathOfTheWild'', various spiritual beings including Koroks, [[DragonsAreDivine dragons]], and the [[HorseOfADifferentColor Lord of the Mountain]] are invisible to almost everybody. Link, of course, can see them just fine.
* In ''VideoGame/GoldenSun'', the protagonists use Psynergy, which is basically magical abilities, which can only be seen by those who can use it. However, at one point you fight in an arena against a series of opponents who are standard humans, leading to some FridgeLogic for what the audience and opponents see when all these gladiators are defeated by a character who just waves his hands around to damage his opponents.
** Subverted by Briggs in ''Dark Dawn'', when he identifies Matthew & Friends because he saw them handwaving around some crates on the other side of the dock and realized it must be Psynergy. Possibly the exception that proves the rule, since Briggs knows about Adepts and Psynergy already and would know what to look for.
* Subverted in ''VideoGame/CityOfHeroes''. Normal citizens will be able to see you use magic, supertechnology, etc. They will come up to you and thank you for beating up the mobs that were being jerks. And if you're playing City of Villains, they will cringe away from you.
* Although Amaterasu from ''VideoGame/{{Okami}}'' is not this trope ''per se'', to most people she appears as nothing more than an ordinary wolf rather than the flaming bronze plate-equipped, red-striped mother goddess of the sun.
* The '[[FaceHugger Aura Beasts]]' from ''VideoGame/PsiOpsTheMindgateConspiracy'', Nick can see them with AuraVision and its implied other psychics can sense them.
* In ''VideoGame/AncientDomainsOfMystery'', a number of foes, including the [[spoiler:Cat Lord]], are invisible, requiring a means of seeing invisible in order to defeat easily. The player can also become invisible, making most enemies incapable of seeing the character, with a notable exception of shopkeepers, who can sense the presence of an invisible character if given sufficient time.
* Angels in ''VideoGame/{{Bayonetta}}'' are invisible to humans. As is the PlayerCharacter herself, most of the time. This is because of {{Parallel Universe}}s.
* [[spoiler:Venat]] in ''VideoGame/FinalFantasyXII'', and perhaps [[spoiler:the rest of the Occuria]], too. This is, in fact, part of the reason that Dr. Cid comes off as being mad, as he carries out conversations with [[spoiler:Venat]] as normally as with anyone else, though to nearly everyone else, it appears as though he's talking to himself.
** [[spoiler:The Occuria]] can't be seen by anyone except Ashe. The other party members hear every word of their conversation, though.
* ''Franchise/TheElderScrolls''
** [[GlowingEyes Glowing]] [[SupernaturalGoldEyes golden eyes]] are a trait of [[OurVampiresAreDifferent Vampires]] (as revealed in ''Skyrim'''s ''Dawnguard'' DLC. It's implied that this is a trait which is Invisible To Normals, and can only be seen by certain other supernatural beings (such as the [[PlayerCharacter Dragonborn]], who has a draconic [[OurAngelsAreDifferent Aedric]] soul).
** In ''[[VideoGame/TheElderScrollsVSkyrim Skyrim]]'', despite anyone being capable of reading the Dragon-Language inscriptions on Word Walls, the Nordic denizens of Skyrim have puzzled for millennia over what their true function was. It's implied that only the Dragonborn is capable of percieving the hidden [[LanguageOfMagic Words of Power]] written upon them.
* In ''VideoGame/MassEffect3'', Shepard is able to understand the Prothean data recordings found on Eden Prime, which everyone else only percieves as noisy static, due to having the collective knowledge of their race implanted in their subconscious during the first game.
* The main character in ''Otherworld: Spring of Shadows'' needed a special amulet in order to see fey creatures (good and bad). In ''Otherworld 2: Omens of Summer'' the "sight" was temporarily granted to her by the little girl she'd spent the entire first game trying to find.
* In ''VideoGame/{{Contrast}}'', only Didi can see Dawn. Also inverted, as Dawn can only see Didi - other people can only be seen by their shadows.
* In ''VideoGame/{{Bloodborne}}'', there are plenty of things that are revealed to you only when you have enough [[ThingsManWasNotMeantToKnow Insight]]. However, having a high level of Insight also makes you more vulnerable to [[YourHeadAsplode frenzy]]. In fact, there are some instances where it's actually ''advantageous'' to go in with as little Insight as possible!
* The MINDs from ''VideoGame/MindZero'' appear as either monsters - either as the summoned monsters or mad monsters - or weapons used by Minders. Taken a step further, Minders can't hear MINDs unless it's their own.
* ''VideoGame/HauntingStarringPolterguy'': Poltergeist Polterguy is completely invisible to the family, only the dog can detect him.
* Anything the Process convert in ''VideoGame/{{Transistor}}'' appears to Red as a non-descript white version of whatever they converted. To the citizens at large, objects just seem to vanish into thin air. Red's possession of the Transistor appears to be the reason she is able to see them where others cannot.

[[folder:Web Comics]]
* In ''Webcomic/SwordCatPrincess'', the extranormal is hidden from the general populace by the Cloaker Field, a field generated by a hidden worldwide race called Cloakers; Jack's father explains this fact to him with a colorful [[http://swordcatprincess.thecomicseries.com/comics/127/ "Cloakers, numbnuts!"]]. Metahumans are not affected by the field, so they can see all extranormal beings and events.
* The gods of ''Webcomic/AMomentOfPeace'' are invisible to the stick figure humans they walk among, but apparently Monster Food, worm like creatures hanging from the very bottom of the food chain, can see them.
* Somewhat Lampshaded in ''Webcomic/MegaTokyo''. Some people in the strip notice the giant drunk turtle, the zombie hordes, and the rent-a-zillas, but most are blissfully ignorant. Ironically enough, the one whom is the most out of touch with reality, Largo, is not only able to see them, but seems rather capable in dealing with them.
** Since the TPD has an entire division dedicated to organising, managing, and cleaning up after the giant drunk turtle, zombies, and rent-a-zillas, you could argue that in Megatokyo, this IS normal life, and everyone's just resigned to it.
** It's later revealed that average people have a "SEP Field" that prevents them from seeing the extraordinary things in Japan ([[{{Kaiju}} giant monsters]], [[MagicalGirl magical girls]], {{Ninja}}, etc.). Only those who have had the field shattered (Junko), are a member of the extraordinary (Miho, Yuki, Meimi), or have a very blurred view of reality (Largo, Dom, Ed) are able to see things for what they are.
** The whole thing is unclear. For example, at the same time as Junko is finally noticing all the weird things that are happening around her, a guy is complaining that if she had been paying attention, a robot wouldn't have smashed his car with a telephone pole. It seems more like half the people notice but don't care, and the other people don't notice.
** Actually its more like each person has a unique perception filter. While Largo can see zombies and the like, he also sees zombies where there are none. Like raves.
* In ''Webcomic/TheDragonDoctors'' [[spoiler: Tomo Wakeman]] is [[spoiler: [[DeadAllAlong a ghost]]]] who is not only invisible, but completely unnoticeable unless she, say... intentionally stomps on a shaman's toes.
* Gradually subverted in ''Webcomic/{{Fans}}'', where despite the best efforts of the sinister shadowy GovernmentConspiracy the truth of what really happens eventually becomes public knowledge.
* The Everto in ''Webcomic/{{Shadownova}}''. [[KilledToUpholdTheMasquerade They have a tendency to kill the people who can see them.]]
* In ''Webcomic/GunnerkriggCourt'', the {{psychopomp}}s are able to reveal themselves to anyone, but usually operate invisibly, since they're forbidden from interfering in the lives of mortals. However, some etherically-gifted individuals--including Antimony and Surma--can see them even when they're supposed to be invisible.
** The [=RoTD=] plays this... weirdly; while Mort and Annie see the requisite occult and arcane trappings, Kat only sees the whole set up as a sort of kitsch haunted house causing her companions to be amazed at her ability to navigate and operate such eldritch mechanisms as a VCR and camcorder.
* ''Webcomic/{{Paranatural}}'': The world is haunted by numerous ghosts and other supernatural creatures, which only spectrals can see. WordOfGod is that while the spirit world is often described as "invisible," the truth is that it's more like a completely different world that only occasionally interacts with the mundane one, while spectrals are people that interact with both. So, for example, if a normal person and a spectral were sunbathing and were shaded by a spirit, the normal person would get a tan while the spectral would not. This also means that mundane cameras can take pictures of spirits without trouble; normal people see nothing, while spectrals see the spirit.
-->'''AltText:''' The number of famous pictures ruined by photobombing spirits... you wouldn't believe.
* In ''Webcomic/{{Shifters}}'' the majority of humanity doesn't know that [[OurWerebeastsAreDifferent Shifters]], [[OurVampiresAreDifferent Vampires]], or any of the other [[SpeciesLostAndFound Veil Races]] exist due to the [[AncientConspiracy conspiracy called The Veil]].
* In ''Webcomic/TheKingfisher'', mortals seem to miss out on the supernatural. Asked why people don't notice them climbing on the side of buildings, Vitus tells Jack, "most people don't look up."
* In ''Webcomic/ElGoonishShive'', the cave housing the artifact that was created to allow women to summon {{Hyperspace Mallet}}s has multiple wards on it to prevent discovery by Muggles including [[http://www.egscomics.com/?date=2010-06-21 this attribute]].
* ''{{Webcomic/Comc}}'': Block cannot be noticed by those who are not {{Fourth Wall Observer}}s.
* ''Webcomic/PennyBlackfeather'' has, as of yet, Nathaniel's ghost and [[TheFairFolk snow spirits]]. Some characters also have WeirdnessCensor strong enough to explain {{Eldritch Abomination}}s as skin disease.
* ''Webcomic/StandStillStaySilent'': Spirits, including extremely hostile and dangerous ghosts, can only be seen by mages, and the LittleStowaway among the crew's mages unfortunately gets his first experience with this while the crew's officially recognized mage is in DeepSleep.

[[folder:Web Original]]
* In the ''WebOriginal/{{Paradise}}'' setting, human characters are randomly, permanently changed into {{Funny Animal}}s (and some are [[GenderBending gender-swapped]] as well). After they Change, characters have an illusory full body disguise of their old human selves where normal human beings are concerned (whether they like it or not), especially early on when the [[WeirdnessCensor "Reality Distortion Field"]] is stronger. A man who turned into a female bear might look much like his old masculine self, just a little overweight—which means he will need to [[WholesomeCrossdresser continue to dress like a man]]. Normals literally cannot tell anything has changed; only other Changed can see them as they are.
* It seems the [[Franchise/TheSlenderManMythos Slender Man]] is only seen when he wants to be seen and rarely shows himself to anyone besides his victims. People who don't know about him are usually safe. Thus, even if he were near right now, perhaps even [[RightBehindMe looming over your shoulder]] as you read this, you wouldn't be able to see him.
* The gods and demigods in ''Literature/ThaliasMusings'', unless they choose to be seen and/or heard. Thalia claims to have used this power to stalk mortal men.
* In the Literature/{{Addergoole}} setting, a double layer of invisibility exists: fae can Mask to hide their unnatural appearance from other fae or fae-blooded, and something called the Blindness of the Gods hides such things from normal Mortals. [[spoiler:Except on Halloween]]
* Possibly the Ginosaji in ''WebVideo/TheHorriblySlowMurdererWithTheExtremelyInefficientWeapon'' series. No one but his victim Jack seems to notice the creepy guy with white makeup and a black hoodie hitting someone with a spoon. When Jack tried to take a photo of the Ginosaji, the only thing that showed up was a strange blur.
* In ''Literature/{{Worm}}'', parahumans gain their powers by connecting to a strange, extradimensional entity which does the heavy lifting for them-giving them RequiredSecondaryPowers and influencing them to be more effective in combat. Chevalier of the [[SuperTeam Protectorate]] can see images of these creatures when he looks at parahumans thanks to his power.
* In ''{{Literature/Moonflowers}},'' the Chinese-American Ned Song is cursed by TheWildHunt into a white wolf's form. Aside from Ogma O'Luain, who can speak to him but [[CanNotSpitItOut can't tell OTHER people about his true identity,]] everyone including his own daughter thinks that he's a giant white wolfdog. When he speaks to Ogma's granddaughter's cat, nobody hears their conversation. It's established that only gods/spirits and deceased humans can communicate with Ned.
* In ''{{Website/STRANGERS}}'', the titular creatures can only be seen and physically interacted with by "sensitives". Sensitivity is an innate ability that cannot be learned, but onlike other examples of this tropes, it has no genetical component and cannot be passed through generations. Additionally, for some reason ethnic, sexual and religious minorities in a local area display more sensitives than the average.

[[folder:Western Animation]]
* Demona in ''WesternAnimation/{{Gargoyles}}'' occasionally used magic spells to prevent mundane people from noticing her or her accomplices. This eventually was done away with when she gained human shape-shifting abilities. Goliath and the other gargoyles simply relied on PlausibleDeniability to keep themselves hidden, but eventually they were seen enough that the Masquerade fell.
** Any member of [[TheFairFolk the third race]] can do this as well, though usually they just shapeshift into a human form.
* The ''Franchise/{{Transformers}}'' made themselves Invisible To Normals by hiding in plain sight. Nobody's gonna see a VW Bug on the road and jump to the comclusion that it's an alien robot, after all.
** Multiple media have had the fact that Transformers do not have a driver eventually draw the attention of humans. Most notably in ''Car Robots''/''Robots in Disguise'', where the desperately unlucky [[YuppieCouple Kelly]] often winds up in the crossfire between the Autobots and Predacons. She does not see them transformed, but starts being seriously freaked out about these strange cars driving themselves. (It doesn't help that her ''own'' car was an Autobot, who dumped her and drove off in the first episode.
*** Of course, the newest comic series has fixed this problem by giving them the ability to project hard-light driver holograms who not only help them hide out but provide a vehicle ([[IncrediblyLamePun haha]]) for their interaction with humans while in their camouflaged state.
*** The first ''Transformers'' comic book series had the Autobots deploy ''inflatable human dummies'' for the same purpose. The dummies could give credit cards to gas station attendants to pay for gasoline...
** In the 1980s cartoons, at least once the humans who knew about the Autobots helped out by 'driving' one. Also, Hound was shown with the ability to generate a hologrammatic driver to further his disguise.
* ''WesternAnimation/MonsterAllergy'' also has monsters invisible to normals. This is used to comedic effect in several episodes, as Elena, the main character's best friend, can't see the monsters, but tries to help out anyway. Later, [[IJustWantToBeSpecial she can finally see them thanks to Greta giving her the Gift of Sight]]. Ghosts, however, are visible to everyone because everyone who isn't a ghost are just "living ghosts".
* In the final battle of ''WesternAnimation/{{WITCH}}'', the heroines are forced to fight in downtown Heatherfield. Normally, such a battle would be easily noticeable, but the girls get around this by having three of their friends create, as Will put it, "one ginormous glamour zone" around the battle, making it appear to anyone standing nearby that the fight is merely a cartoon taking place on a large television screen which has been recently built on a nearby building. Of course, in order to maintain this illusion, they must still prevent any debris knocked around in the fight from crushing the people below.
