->''"I could be bounded in a nutshell and count myself a king of infinite space, were it not that I have [[TropeNamer bad dreams]]."''
-->--'''Theatre/{{Hamlet}}'''

TheHero has [[DarkAndTroubledPast hurt]] in his {{Backstory}}. [[HurtingHero A world of hurt.]] Or worse, he had to ShootTheDog and [[DirtyBusiness is wracked with guilt]]. Or ''[[SurvivorGuilt both]]''.

Not that he will show it, not him, not TheStoic. (Perhaps just on this topic, but that's where it hurts.) He won't even say DontYouDarePityMe; he would if someone sympathized, but his pain is too hidden for anyone to think of pitying him. He won't even suffer a NotSoStoic moment. Or SandInMyEyes.
So how do you show the readers (and sometimes the other characters) he's not actually just [[WeHaveReserves cold]] and [[MoralEventHorizon heartless]]? How do you humanize him without CharacterDerailment? Or inappropriate CharacterDevelopment for the story?

You give him Bad Dreams.

'''There are various options:'''

* Mildest, he can be restless in bed or [[TalkingInYourSleep mutter to himself]] -- or even start shouting. Or other characters can comment on it.
* Show the dream sequence, showing his terror and a remarkably lucid account of the trauma (possibly a FlashbackNightmare, possibly symbolically represented), and how he woke in horror. Either a NightmareSequence, DaydreamSurprise or AllJustADream is possible.
* Have him [[TalkingInYourSleep talk in his sleep]] (or in a delirum). This is used, often, to let other characters in on the secret. His talk is often remarkably clear, lucid, {{exact|Eavesdropping}}, and detailed. True, the significance often has to be pieced together, but it can be done.

As soon as he wakes (often [[CatapultNightmare by sitting up in bed]]), he will be back to normal. However, he may suffer [[TheInsomniac Insomnia]], which can reach dangerous proportions if they are RecurringDreams. If he woke everyone else screaming, he will apologize for disturbing them. Usually. Once in a while, someone will actually admit to a secret at this point; this can be [[EpiphanyTherapy unrealistically beneficial]]. If the character suffers from GoMadFromTheIsolation, he will often not be able to remember that he is safe until several moments after waking.

If it stemmed from MyGreatestFailure, may overlap with AnxietyDreams, and be fixed with it if the character tackles the problem the second time round.

''Visions'' about bad things, whether [[DreamingOfTimesGoneBy past]], [[DreamSpying present]], or [[DreamingOfThingsToCome future]], or plain old ordinary dreams that are just unpleasant, are not Bad Dreams; Bad Dreams indicate trauma. (And TruthInTelevision, really can stem from trauma.)

Can be used to show the extent of trauma for any person, but obviously more likely for the Stoic, the EmotionlessGirl, BrokenBird , and the like. Or in cases where the character would never show his pain before a particular person. On the other hand, it is a convincing way of demonstrating trauma for, and humanizing, anyone, since you can't fake dreams. May be used to reveal the true character of NoHeroToHisValet (type 2). Or demonstrate that BeingEvilSucks. Or to show that TheAlcoholic is DrowningMySorrows. TheCaptain is prone to Bad Dreams because he cannot show weakness in front of his men and [[AFatherToHisMen feels responsible for them]].

YourWorstNightmare may be mistaken for Bad Dreams. When the character suffers from TraumaInducedAmnesia, often overlaps with DreamingTheTruth.

Contrast DreamingOfThingsToCome. When the dreams are symbolic, they can not always be distinguished; dreams of a villain could be remembering the past encounters, or foreshadowing future ones. Also contrast TalkingInYourDreams. The character may not be able to tell that someone is communicating because the means are bringing up memories.

May be a FeverDreamEpisode. Supertrope of FlashbackNightmare, which always shows the nightmare and is literal. These are often RecurringDreams, at least by implication. May be caused by buried memories from AlternateIdentityAmnesia.

[[foldercontrol]]

[[folder:Anime and Manga]]
* Guts from ''Manga/{{Berserk}}'' gets these a lot because of his [[DarkAndTroubledPast horrible childhood]]. It only gets worse when he gets the [[MagneticPlotDevice Brand Of Sacrifice]].
* Tarou from ''Anime/GhostHound'' has been having these ever since he got kidnapped when he was four-years-old.
* Asuka from ''Anime/NeonGenesisEvangelion'' has one right beside shy protagonist Shinji on their final night of having to [[ItMakesSenseInContext sleep together]]. It's about her [[FreudianExcuse mother]].
* Lucy from ''Manga/ElfenLied'' demonstrates all three of the variations at one point or another. One of her Bad Dreams lasts for more than an episode.
* ''Manga/FruitsBasket'':
** Yuki suffers a Bad Dream about his [[AbusiveParents mother]]. He is worried because he hasn't had it in a while.
** Rin also suffers a Bad Dream about her [[AbusiveParents parents]] when she's ill.
** At one point, Tohru has a bad dream about the day her mother left and was hit by a car and killed. The dream itself wasn't bad (just her mother bidding Tohru goodbye as she left for work), but Tohru watches while knowing what will happen and wakes up as she tries to warn her mother not to leave.
* ''LightNovel/HaruhiSuzumiya'' empowers total strangers to come in and mop up her bad dreams, then has a good dream with her SO.
* ''Manga/{{Hellsing}}'' : Alucard, of all people, has bad dreams of when Abraham Van Helsing defeats him, and later has hallucinations containing homages to various films. He's properly freaked out about this. This is exaggerated in the fifth OVA.
* ''Anime/DigimonAdventure02'' basically managed to turn Ken Ichijoji from the [[KickTheDog psychopathic Big Bad]] into TheWoobie by using this method.
* In ''CountCain'', the titular Cain suffers near-constant nightmares due to his father's abuse and generally miserable childhood. Peculiarly, his own bad deeds, [[spoiler: including several poisonings,]] don't seem to bother him at all.
* ''Manga/MahouSenseiNegima'':
** [[OurVampiresAreDifferent Evangeline]] has recurring nightmares of the day the Thousand Master rejected her, defeated her, and sealed her in Mahora Academy.
** After the events at the start of the Magic World arc, Negi himself had one where he saw all his students petrified. It ends with the petrified Asuna shattering.
* Shows up multiple times in ''Manga/ChronoCrusade''.
** Chrono is shown having nightmares both after Rizelle is killed (implying guilt for Chrono and also hinting at his [at the time] unrevealed {{backstory}}) and in a flashback (hinting that he possibly has something like [=PTSD=] after a battle while leaving the demon's home world).
** Rosette also has a bad dream after a traumatic battle that's half-flashback and half-symbolic, which sets up the uncharacteristic despair she's in for the rest of the chapter.
** In the anime, Rosette has a bad dream about Joshua to foreshadow the reveal about her backstory.
* ''Anime/PokemonTheRiseOfDarkrai'' features a Pokémon specifically capable of giving any sleeping person Bad Dreams, and is physically incapable of doing otherwise. When the main character, Ash, is put to sleep, he's given a vision of Palkia's appearance in the city. Of course, he doesn't realise what's going on until it's too late.
** Additionally, due to Palkia's Space Warping powers being out-of-control at this point, any Pokémon put to sleep will have their nightmares in full view for everyone to see. Most of the Pokémon dream of being chased by "something frightening" - Lickylicky on the other hand dreams that it has transformed into Baron Alberto (not strictly the villain, more of a {{Jerkass}}) and thus the actual Baron ends up turning into Lickylicky. He even takes advantage of this in an attempt to battle Darkrai and begins using attacks. He loses. When Palkia wakes up and regains some control of its powers, the images of nightmares fade away and the Pokémon all inexplicably wake up at the same time.
* In ''LightNovel/FullMetalPanic'', Sousuke is eventually shown to have nightmares concerning [[spoiler: Kaname]], along with his dead mother (who died protecting him, and told him to "fight" and "never give up"). These nightmare sequences are pretty much the only mention or thoughts he gives of his mother (as he [[TheStoic isn't a very sentimental person]]), and without them, it would be made rather ambiguous whether or not Sousuke even ''remembered'' his mother (since she died when he was 3-4 years old, and he was even shown going mute and repressing memories of her when he was young, and only got better with Kalinin's help).
* Happens early on in ''Manga/FullmetalAlchemist'', with Ed [[spoiler:waking up from a dream of his mother with her flesh falling off her body.]]
* Maria in ''VideoGame/SakuraWars'' has {{Flashback Nightmare}}s about her time as a soldier in Russia and particularly about the death of her commanding officer (who was either her mentor [anime] or her love interest [manga]... the original game is unclear on this point), for which she feels responsible.
* In ''Manga/VirginLove'', Kaoru has a lot of trouble catching sleep because he always dreams of his abusive childhood.
* In the first chapter of ''Manga/SangatsuNoLion'', Rei suffers through bad dreams while sleeping over at the Kawamoto residence after bottling up all of his negative emotions regarding his victory over his father in shogi earlier in the day. While bringing him bedsheets to sleep with, Hina notices Rei crying in his sleep as she takes off his glasses, causing her concern..

[[folder:Comic Books]]
* Heather Hudson has a dream sequence after the death of her husband in ''ComicBook/AlphaFlight'': in the graveyard, one by one, the team members leave her. Then her dead husband's rotting corpse rises out of the grave and chases her.
* Franchise/{{Batman}} in various media and usually focusing on reliving the night of his parents' murder, with story appropriate variations.
* {{Magneto}} suffers these from his experiences in the Holocaust and his daughter's death afterwards.
* At the end of ''ComicBook/{{Watchmen}}'', [[spoiler: Ozymandias]] seems perfectly content that he did the right thing, but seems to show a hint of doubt when he mentions his dream of "swimming towards a terrible...never mind", drawing a parallel between his story and the mariner of the comic-within-a-comic, in which [[spoiler:a man commits horrible atrocities in order to save his home from attack from a dreaded ship of the damned. However, the attack never happens, and he eventually joins the ship, having ironically lost his soul through his attempts to save his village]].

* A variant of this trope appears in ''Comicbook/ThePunisherMAX''. Frank's worst dream is actually a happy dream of an alternate future in which his family didn't go to the park and he is a grandfather who is having dinner with his wife, children, children-in-law, and grandchildren. The reason that Frank considers this a bad dream is because it painfully reminds him that his family is dead when he wakes up.
* In "Swamped" a vegetative Comicbook/SwampThing had a confused, pun-sprinkled nightmare about Linda Holland and his humanity.
* In ''The Killing Dream'' arc of ComicBook/{{X 23}}'s solo series, Laura has recurring nightmares of being chased or hunted, which lead to a BattleInTheCenterOfTheMind against a demon attempting to recruit her into his service.
* Mindf*** from ''Comicbook/{{Empowered}}'' suffered from nightmares related to her brother's efforts to enhance her telepathic powers by [[DisabilitySuperpower removing "crutches" like her eyes and tongue]]. The one time she fell asleep without elaborate isolation protocols once she could set them up was in the arms of her lover... [[PowerIncontinence who got to share]], and [[SugarWiki/HeartwarmingMoments insisted on her remaining]] when they both [[CatapultNightmare woke up]].

* In ''FanFic/CadenceInAMinor'', both Shining Armor and Princess Cadence have recurring nightmares about the ordeals they went through when a changeling queen replaced Cadence before their wedding.
* Something of a {{Motif}} in ''Fanfic/ChildrenOfTime'':

** Midway through the first season, Sherlock undergoes an AndIMustScream experience. He comes back from it physically whole but thoroughly shaken, with sleepless nights ahead implied.

** Both Holmeses continue these patterns into the second season with TearJerker results.

[[folder:Film]]
* In ''Film/BreakfastAtTiffanys'', Holly gets into bed with Paul and talks in her sleep about, apparently, losing her beloved brother in the snow. The trope is slightly averted in that she'd already revealed, earlier in that scene, that she worries about her brother, but not the extent to which it distresses her.
* Wolverine in the ''Film/XMen'' movies is shown to have some nasty nightmares about his experience with Weapon X. Nightmares so nasty he wakes up and stabs whatever's in front of him.

[[folder:Live Action TV]]
* Commander Sinclair in ''Series/BabylonFive'' was plagued with dreams of the [[LastStand Battle of the Line]].
* ''Franchise/{{Buffyverse}}'':
** In addition to DreamingOfThingsToCome, Buffy experiences guilt-fueled dreams about her encounter with Faith in the season 3 finale episode "Graduation Day" (part 1). These dreams begin peacefully but become Bad Dreams because of Buffy's guilt. The dreams appear in episodes involving Faith after the aforementioned encounter.
** Likewise at the beginning of Season 3, Buffy's dreams reflect her guilt at killing a re-souled Angel in the Season 2 finale. The dreams stop after she confesses her action to Giles.
** Genevieve is plagued by prophetic dreams and the memories of past Slayers and their deaths. One of the reasons she wants to kill Buffy is because Roden lied and told her the dreams would end when Buffy was dead.
** Angel has them with such regularity, one wonders how he catches ''any'' winks without valium. Yet another downside to being undead: vampires share a PsychicLink with their kin. When a vampire he sired 100 years ago starts killing people locally, Angel feels it. In ''Angel'' Season Two, Angel starts having... erm, 'dreams' about his maker. It is later revealed that Darla is dosing him with occult herbs to drive him into a frenzy.
* BurnNotice: Michael has these in S5 of Burn Notice due to the stress of being targeted by the organisation that burned him and his fear the organisation still exists.
* Spencer Reid in ''Series/CriminalMinds''. In the two-parter "The Instincts" and "Memoriam'', the entire plot is driven by the fact that he is having horrible dreams that include finding a dead body behind a dryer, seeing babies at a crime scene, and being devoured by leeches (he wakes up in the middle of the night at a victims house shouting "Morgan, get 'em off me!", [[HoYay/CriminalMinds which is a huge piece of bait for shippers]]). He later connects these dreams to his father in "Memoriam" and the investigation is on.
** Earlier in the show, Rossi is haunted by nightmares relating to the Galen murders.
* The ''Series/DoctorWho'' special ''The End Of Time'' begins with everyone on Earth having nightmares of a laughing man.
** In "The Next Doctor", the amnesic, possible future incarnation of the Doctor has Bad Dreams, stating that with everything a Time Lord has seen and done, of ''course'' he has Bad Dreams. The Tenth Doctor simply replies "Yeah,". [[spoiler:Jackson Lake isn't the Doctor though. His Bad Dreams are caused by the death of his wife and kidnap of his son that he's suppressed the memory of out of grief.]]
** In the Series Five episode "Amy's Choice", the Eleventh Doctor's cheerful carefree manner is revealed to be a mask at least some of the time. This is revealed in two dreams caused by psychic pollen. Amy and Rory are also included in these dreams, so they end up seeing Eleven's inner darkness for themselves.
* "They've Got a Secret", a first-season episode of ''Series/{{Farscape}}'', shows a hallucinatory version of this: D'Argo is awake and walking around the ship, but is hallucinating, and thinks that the other characters are actually people from his past. They eventually realize this, and play along to get him to snap out of it. We (and his crewmates) learn about his wife and son in this way.
* River from ''Series/{{Firefly}}'' has these as a result of [[MindRape what happened to her]] at the [[SchoolForScheming Academy]].
* The later-period ''Series/{{Mash}}'' episode "Dreams" consists of each of the exhausted characters falling asleep and dreaming a symbolic but horrific dream reflecting the war (except Potter, who has a really nice dream about home). At the end, as they're all talking about going to bed, Winchester quotes, "[[Theatre/{{Hamlet}} To sleep, perchance to dream]]"...and everyone decides that they'll have another cup of coffee, after all.
** In "Hawk's Nightmare", the imitable Hawkeye goes through {{sleepwalking}} and terrifying dreams from which he wakes screaming loud enough to rouse most of the camp. It's determined that he's having a sane reaction to his insane situation, and the worst his childhood had to offer was $20 he may or may not owe an old friend.
* Robin from ''Series/RobinHood'' has nightmares about fighting in the Holy Land, but oddly none (that we see) about the fact that [[spoiler:Marian]] was murdered in the Holy Land. On the other hand, Guy is seen having a nightmare after he kills [[spoiler:Marian]].
* In the first series of ''{{Spaced}}'', Tim wakes from dreams of his ex-girlfriend shouting out her name on several occasions.
* The main characters from ''Series/{{Supernatural}}'' get hit by this a few times.
** In season four, Dean spends many nights tossing over his nightmares of hell. In season seven, Dean is once again having nightmares, this time about [[spoiler: Castiel's death and Sam's hallucinations. Well, mostly about killing Sam's monster friend]].
** Sam had nightmares throughout Season 1. While some were visions, the ones where he watched his girlfriend die over and over again still affected him like this. In season seven, [[spoiler:his hallucinations of Lucifer began as nightmares.]]
** In one episode, Bobby's nightmares are used against him by a MonsterOfTheWeek, as are Dean's.
* ''Series/TheXFiles'':
** Agent Mulder often relives his sister's kidnapping during nightmares.
** In season 2, Mulder dreams of Scully being tortured by those who abducted her.
** Reversed in season 8, in which Scully has nightmares of Mulder being tortured ruthlessly by aliens. These get so regular she panics when she's ''not'' having them anymore, for fear that his death may be the reason.
* The two-part ''Series/ThirdRockFromTheSun'' episode "A Nightmare on Dick Street" has each of the aliens experiencing a vivid bad dream (shown in [[ThreeDimensionalEpisode 3D]], no less).
* In the ''Series/{{Torchwood}}'' episode "Small Worlds", Jack Harkness dreams about his last encounter with TheFairFolk, and how all his men died.
** In "Adam", the titular antagonist, makes Jack relive in his dreams, the repressed memories of the death and enslavement of everyone on his homeworld, [[spoiler: The Boeshane Peninsula]], which was the day he lost his little brother.
* In Series/{{Sherlock}}, John Watson is shown to have nightmares about his time in Afghanistan.
** Subverted in that those dreams are revealed not to be actually nightmares at all, but because;
--> '''[[spoiler: Mycroft]]''': You're not ''haunted'' by the war, Dr. Watson. You ''[[BloodKnight miss]]'' it!
* In an episode of ''Series/{{Tales From the Darkside}}'', a gangster is given a chance to dream beautiful dreams for all eternity. During the trial run he experiences occasional nightmare visions, but is assured that when he goes into the permanent dream state, those will disappear. He goes for it, and it does not end well for him.

[[folder:Video Games]]
* In one of the multiple endings, [[spoiler:Albel Nox]] from ''VideoGame/StarOceanTillTheEndOfTime'' is accused by the protagonist of causing him to wake up every night with his screaming from nightmares. [[spoiler:Albel's [[SurvivorGuilt considerable angst]] over his dead father is ostensibly the cause. Albel's father was a renowned and successful leader in Airyglyph's military, and he died when Albel failed the test to join the same military branch, the ''[[OurDragonsAreDifferent Dragon]]'' Brigade. This would have resulted in Albel dying in a fire, if his father didn't [[HeroicSacrifice step in to save Albel at the cost of his own life.]] Even though Albel's father saved his life, Albel still got burned pretty bad and lost most or all of his left arm.]]
* Cloud from ''VideoGame/FinalFantasyVII'' experiences these regularly over the course of the game (sometimes while he is wide awake).
** Haunted by his actions in the attack of Mysidia, and distraught by the King stripping him of his rank, Cecil from ''VideoGame/FinalFantasyIV'' suffers from bad dreams on the night before his assignment on the Village of Mist. Rosa is there to comfort him.
** In ''VideoGame/FinalFantasyVI'', [[{{Ninja}} Shadow's]] backstory is ''only'' revealed through his flashback Bad Dreams when you rest at an inn.
* ''VideoGame/MaxPayne'' gets these a lot as a result of [[MyGreatestFailure failing to save his wife and baby girl]].
* Serge from ''VideoGame/ChronoCross'' suffers a melancholy dream about Kid after seeing [[GrandTheftMe Lynx take over his body and stab her]], and getting shunted into another dimension in the aftermath.
* At the end of ''VideoGame/MetalGear2'', Snake yells at Big Boss that he's had terrible nightmares for the last four years, and says that by killing Big Boss he can end the nightmares. Not only does this not work, it's [[{{Bathos}} not terribly conducive to drama]] when Snake's nightmares were [[CompressedVice never actually mentioned until that one scene]]. On the bright side, the nightmares were eventually developed into PTSD and this was used to flesh out Snake's character into something more rounded.
** ''VideoGame/MetalGearSolid3'' has a bonus scene if you save while in the prison cell which is Snake's (somewhat odd) nightmare (Snake's afraid of vampires, and Para-medic talks about Dracula after you save). The scene is actually a demo of "Guy Savage", a game that was never released. Following the dramatic wake-up you can call your support team to get some humorous conversations (like SIGINT's rather disturbing dream).
** In ''VideoGame/MetalGearSolidPortableOps'', [[AnIcePerson Python]] mentions having nightmares every night due to the people he's killed as an assassin, which was only training for him to kill Snake. By killing Snake, he reasons the nightmares would go away.
* Aribeth in the original NeverwinterNights campaign has a lot of these in chapter 2
* In ''VideoGame/TheElderScrollsIVOblivion'', the player character has some [[http://www.uesp.net/wiki/Oblivion:Vampirism#Vampire_Nightmares pretty scary dreams]] if they become a vampire. It's a good thing they didn't actually show them as a cinematic!
** In ''[[VideoGame/TheElderScrollsIIDaggerfall Daggerfall]]'' it was. It was suitably creepy.
* In the ''Point Lookout'' DLC to ''VideoGame/{{Fallout 3}}'', your character is exposed to hallucinogenic swamp plants, and goes on a bad head trip through the swamp; including mocking bobble-heads with inscriptions insulting you and your mother's death. Then when you wake up, it's revealed somebody cracked open your head and cut out a chunk of brain.
* In the ''Franchise/DragonAge'' series, Grey Wardens suffer Bad Dreams after the Joining [[spoiler: due to their new connection to the Darkspawn taint that lets them hear the Call of the Old Gods]]. How bad it gets varies from Warden to Warden; a rare few are almost fine, while others can have trouble sleeping their entire lives. [[spoiler: The worst part is that this is the warmup. After thirty years or so, the dreams get really bad, showing the taint is overcoming the Grey Warden. Rather than succumb to it, the Wardens travel to the Deep Roads to die while killing as many Darkspawn as possible.]]
* Bao-Dur and the Exile in ''VideoGame/KnightsOfTheOldRepublicII'' are revealed to have bad dreams about the Mandalorian War, particularly the final battle. In a randomly generated cutscene on the Ebon Hawk, the Exile walks the ship while everyone else is asleep - except for Bao-Dur, who can't sleep for [[WarIsHell the same reasons]], and sympathises.
* ''VideoGame/FalloutNewVegas'' gives us potential companion [[ColdSniper Craig Boone]], who was forced to Shoot the Dog twice. After you gain his trust, he'll tell you that he thinks about [[spoiler:the massacre of Bitter Springs]] even when he sleeps. He also states that a dream made him reconsider traveling with the Courier to the site of the massacre.
* Kratos's motivation to serve the gods in the first ''VideoGame/GodOfWar'' game is to rid himself of the nightmares that he'd been plagued with since he killed his wife and child. [[spoiler:Unfortunately, while he ultimately obtains forgiveness from the gods for his service, they don't take away the nightmares.]]
* The Franchise/{{Pokemon}} [[CastingAShadow Darkrai's]] Special Ability is named this. It hits an opposing Pokemon for 1/8 of its max HP at the end of every turn if it is sleeping. The move Nightmare does the same thing, but it does 1/4 of their max health instead.
* In ''VideoGame/MassEffect1'' Shepard can tell Liara that they're being kept up at night from dreams and visions from what Shepard saw when they accessed the Prothean beacon.
** When Liara asks Shepard at the end of ''The Lair of the Shadow Broker DLC'' for ''VideoGame/MassEffect2'', Shepard will reply that they're no longer having visions, "if that's what you mean."
** And in ''VideoGame/MassEffect3'', they have a recurring dream about [[spoiler: a young boy they failed to save on Earth.]] It is indicated in dialogue that [[IronWoobie Shepard]] now suffers nightmares about [[spoiler: The Fall of Earth]] every time they goes to sleep.
* In an e-mail conversation in ''VideoGame/AssassinsCreedBrotherhood'', Rebecca says that she hears Demond ''screaming'' during the night. Apparently, there are some psychological drawbacks to strapping a person to a machine that messes with their memories for several hours at a time. Who would have guessed?
* In ''VideoGame/TalesOfTheAbyss'', main character Luke is realistically traumatized by the first time he kills a human soldier, even though it was in self-defense. Late in the game, after much character development, Jade mentions that he knows Luke continues to wake in the night trembling from nightmares after days when they have to kill people. This seems to underscore that even when Luke was a brat at the start of the game, he still had the essential kindness toward others that he develops in more obvious ways later on.
* Nightmares make up multiple stories in VideoGames/FallenLondon. Following a nightmare path all the way through can leave a player permanently changed, and there is a creature called the Eater of Chains that attacks people in their dreams. Have too many nightmares, and you might end up having a stay at the [[BedlamHouse Royal Bethlehem Hotel]]

[[folder:Visual Novels]]
* Miles Edgeworth in the first ''Franchise/AceAttorney'' game admits that he's dreamed of his father's murder almost every night for the last ''fifteen years''.
* ''FateStayNight'': Shirou Emiya still has dreams about the end of the fourth Grail War and is wracked by his helplessness to save those around him at the time. As he learns more about the War the dream gains a new feature: [[spoiler:The true form of the Grail when it partially manifested]].
* ''VisualNovel/KatawaShoujo'' has this play a part in two of the five stories, [[ShrinkingViolet Hanako Ikezawa's]] and [[GenkiGirl Emi Ibarazaki's]]. Hanako's stem from the origin of her scars and is left at that, but Emi's end up being a significant factor in her arc.
* In ''VisualNovel/LittleBusters'', both Komari and Kud's routes involve them having bad dreams. Komari's are perfectly peaceful scenes of herself with an older boy acting as her brother, but they make her quite uneasy because she doesn't have a brother and feels disappointed whenever she wakes up. Kud has the more traditional example of recurring nightmares after she hears that [[spoiler:her home country is falling apart after a big explosion of a rocket there.]] In her good route the player never finds out why, but in the bad ending it's revealed that [[spoiler:she was DreamingOfThingsToCome - namely, her mother being executed.]]
* In ''VisualNovel/LuxPain'', although Atsuki haven't dreamt them since joining FORT, the dream about how his parents died, as well as his sister being ''eaten'' by Silent infectees and barely surviving, came back in Episode 1 and it counts. No one knows about it until [[spoiler:Rui accidentally reads it with her fortune-telling powers]].
* ''YoJinBo'' allows you to [[TalkingInYourSleep have a conversation]] with [[spoiler: either Yo or Ittosai]] if you [[spoiler: choose to stay in the cave with them]] while on their [[MultipleEndings respective paths]]. [[spoiler: Yo dreams about a time when he accidentally hurt his mother as a child, and Ittosai flips out and attacks Sayori, believing her to be his father.]]

[[folder:Web Comic]]
* Type Two is the primary way in which the reader learns Lexx's [[DarkAndTroubledPast backstory]] in ''AlienDice''. Early in the story, Chel wakes Lexx up because he was crying out in his sleep while remembering [[spoiler: one of his first attempts at suicide]]. He refuses to share his past with her.
* In ''Webcomic/TheOrderOfTheStick'', V [[http://www.giantitp.com/comics/oots0623.html wakes from a trance with Bad Dreams]]--which are actually memories, as elves' trance isn't technically sleep.
* ''{{Metanoia}}'''s Star Tyrian, {{Lampshaded}} [[http://metanoia.studiowhippingboy.com/template.cgi?1+ 2+ 19 by the character]].
* ''Webcomic/TowerOfGod'' - Rachel has nightmares of Baam being surrounded by companions and her being alone [[BeCarefulWhatYouWishFor among the stars.]] Later she claims having nightmares of [[spoiler: Baam's death]].
* Several times in ''PlatinumGrit'', Jeremy has nightmares about his insane cousin Dougal coming back for revenge. Sometimes with a few odd goings on to suggest they're more than dreams.
* Shopclerk, from AdorableDesolation wakes up screaming every morning, but he doesn't remember what he's been dreaming about.
* BobAndGeorge [[http://www.bobandgeorge.com/archives/020306c Megaman has them, apparently]]
* DominicDeegan: [[http://www.dominic-deegan.com/view.php?date=2003-09-05 After the battle]] [[http://www.dominic-deegan.com/view.php?date=2003-09-15 And for someone else, too.]]
* Shelley has them in WapsiSquare.
** [[http://wapsisquare.com/comic/notnightmares/ and not Shelley alone, though they thought they were just nightmares]]
* In ''Webcomic/ElGoonishShive'', Grace [[http://www.egscomics.com/?date=2002-05-20 used to have them]] before [[spoiler: she defeated Damien and faced her fear of her beastly side]].
* In ''PricklyCity'', the voter who cast the deciding vote to elect Kevin, Lost Bunny of the Apocalypse, to the Senate (and get him out of Prickly City), has dreams of his campaign for the presidency -- combining this with AnxietyDreams.
* ''NinthElsewhere'': Since the story takes place almost entirely in one of the character's subconscious, this trope was inevitable.
* In ''BlueYonder'', [[http://www.blueyondercomic.net/comics/1173198/blue-yonder-chapter-1-page-8/ Jared dreams of his family -- ending with the moment they were attacked.]]
* In ''Webcomic/DocRat'', [[http://www.docrat.com.au/default.asp?thisItem=745 Pippie has had dreams of ghosts since her family was killed in a brushfire.]]
** [[http://www.docrat.com.au/default.asp?id=strip&thisitem=1279]], when TalkingInYourSleep, [[http://www.docrat.com.au/default.asp?thisItem=1286 proves to be having this.]]

* In ''{{Homestuck}}'', Alternian trolls as a race experience horrific nightmares and sleep in sopor slime to suppress the visions. They're implied to be caused in part by Doc Scratch.

[[folder:Web Original]]
* In ''Roleplay/TheGamersAlliance'', Refan and Ronove suffer from these. In Refan's case it's mostly about the guilt for having killed for the first time, but he also has flashback dreams which make him gradually remember who was responsible for his mother's death, and later he even has nightmares about his nemesis who contacts him telepathically. Ronove's dreams make him gradually recover his memory, and their content foreshadows that he is in fact a [[spoiler:former demonic Dreadlord]].
* Kate of ''KateModern'' is frequently disturbed by strange dreams featuring needles, morbid imagery and sinister figures. In the GrandFinale "The Last Work", it is implied that these are memories [[spoiler:of being a baby in an Order laboratory]].
* These happen all over the place in ''BrokenSaints''. Chapter 7, Lucid, is all about the lucid dreams Raimi's been having.
* Considering how traumatic her entire life is, [[DarkMagicalGirl Himei Shoutan]] of ''SailorNothing'' gets these very often. Most of the time, it's just pieces of her memory replayed for her viewing pleasure, but sometimes, her nightmares go all creative on her. She doesn't wake from them screaming. At least, not anymore.
* Ayla Goodkind of the Literature/WhateleyUniverse routinely has Bad Dreams that reflect her self-doubts and the horrific traumas she has gone through since she became a mutant. Most of the Phase stories have at least one night of nightmares.
* WebVideo/TheNostalgiaChick screams at the WillSmith [[WesternAnimation/SharkTale fish]] to please leave her nightmares.
** Likewise, WebVideo/TheNostalgiaCritic states Pauly Shore's [[Film/BioDome creepy laughing]] will be the new soundtrack to his night-terrors for a while.
* Egg of ''Roleplay/{{AJCO}}'' has suffered from them on-and-off throughout most of her life but after [[spoiler: she contributed to Pi's death]] they came back increased tenfold, to the point that she was waking up in the middle of the night physically nauseous and unable to get back to sleep due to the hallucinations of blood staining her hands and dripping from the walls. They've been decreasing in intensity since she left the Silo to live in Katton, however.
* Ti'Cira Hawk from ''TheGunganCouncil'' has reoccuring nightmares reliving the torture sessions under the hands of Azrael Daragon during her time in slavery.
[[/folder]]

[[folder:Western Animation]]
* Done without seeing the actual dream in ''WesternAnimation/BatmanBeyond'', when Payback calls himself Bruce's worst nightmare, and Bruce simply retorts [[SugarWiki/MomentOfAwesome "You have no idea what my nightmares are like."]]
** Similarly notable in an episode of ''WesternAnimation/JusticeLeague'' where the team was being locked inside their own nightmares. Batman, running on willpower and coffee, struggles mightily to stay awake, and when bad guy taunts him, he says, "You don't want to see my nightmares." That ChekhovsGun [[ChekhovMIA doesn't fire, though]], and he takes his opponent down before passing out.
* ''XMenEvolution'' has [[TheDragon Mesmero]] using his PsychicPowers to enter the minds of a bunch of X-Kids as they sleep, then he turns their dreams into nightmares, and ultimately {{mind rape}}s them [[BrainwashedAndCrazy into serving him.]]
** In ''Ghost of a Chance'', Kitty has a bizarre dream about befriending a girl named Danielle, and then she has more hallucinations/bad dreams about Danielle, including one where the mansion begins to flood and ooze slime from the walls, while a zombie-like Danielle calls for Kitty to help her. [[spoiler:It turns out that Danielle is a mutant with psychic abilities, who had been trapped in a cave-in near where Kitty visited earlier in the episode. The dreams she was sending Kitty were messages for rescue before her body was drowned. We also get hints in the series that Danielle wasn't very popular in her hometown because she had a tendency to give other people bad dreams by mistake.]]
** {{Wolverine}} also has nightmares about the Weapon X program; the episode they appear in has some justification, though, in that his brain is being remotely messed with by the original scientist in charge of the Weapon X program.
* The Season 2 opener for ''WesternAnimation/AvatarTheLastAirbender'' shows that Aang has been experiencing nightmares (for what was probably the better part of a month) about his actions under the [[UnstoppableRage Avatar State]] in the previous season finale.
** Zuko's had some bad dreams, too, mostly having to do with his struggle to [[WellDoneSonGuy please his father]] and his desire to fulfill his destiny, as seen in S2E17, "The Earth King."
** Season 3 has an entire episode (called [[ExactlyWhatItSaysOnTheTin "Nightmares and Daydreams"]]) devoted to Aang's stress-induced nightmares before invading the Fire Nation. He forgoes sleep and decides to spend his days ''and'' nights training, resulting in a series of hilarious sleep-deprivation induced daydreams. Most of his so-called "nightmares" are also PlayedForLaughs ("Oh no, I forgot my pants and my math test!"), but at least one of them is seriously scary.
* The finale of ''WesternAnimation/CourageTheCowardlyDog'' featured two of these, resulting from Courage's constant berating from an evil teacher. Both of them involve bizarre creatures taunting him about his imperfections. And these are ''nasty'' dreams, especially the first, more infamous one.
* Subverted in an episode of ''WesternAnimation/TheFairlyOddparents''. Timmy is very guilty of releasing the town goat and blaming Vicky that he has "wish nightmares" brought on by wishing in his sleep, creating a garbled pink mess in his bedroom.

[[folder:Real Life]]
* People with post-traumatic stress disorder frequently have nightmares about the traumatic event in question.
** In fact, this is a common enough symptom that treatment approaches for PTSD that target nightmares explicitly have been developed (and shown high efficacy).
* People who fall into comatose states frequently have "dreams" in this vein as well, the memories of which usually haunt them for years to come. One member of the ''VideoGame/AdventureQuest'' forums allegedly was tortured by demons for three months while he was in a coma following an ATV accident and incorporated many of his hellish sequences into his stories.
