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

At some point in the past, Bob TheHero got [[DarkAndTroubledPast hurt]]. [[HurtingHero Badly hurt.]] He suffered some horrible injury. He saw people he loved being brutalized or murdered. He had to ShootTheDog and [[DirtyBusiness has been living with the guilt ever since]]. Maybe it was even ''[[SurvivorGuilt all of the above]]''.

But Bob doesn't want anyone else to know he's still hurting; not him, not Bob TheStoic. He won't even say DontYouDarePityMe; he ''would'' if anyone showed him pity, but his pain is too well concealed for that. He won't even suffer a NotSoStoic moment or brush off the tears that come in a rare unguarded moment with "There's SandInMyEyes."

So how do you show the readers (and sometimes the other characters) that Bob's impassive demeanor is the result of superhuman control and iron will, not a sociopath's LackOfEmpathy? How do you show his breaking heart without CharacterDerailment? Or inappropriate CharacterDevelopment for the story?

You give him Bad Dreams.

'''There are various options:'''

* At its mildest, we see that Bob is restless in bed, prone to [[TalkingInYourSleep muttering to himself]], crying, or even screaming. He may also sleepwalk. The audience always sees this; other characters may or may not be aware.
* Another option is to show Bob's dream sequence, letting us view his terror and a remarkably clear account of the trauma (possibly a FlashbackNightmare, possibly symbolically represented), and Bob waking in horror. A NightmareSequence, DaydreamSurprise or AllJustADream are all possible options.
* A third option, useful for letting the cast in about Bob's secret pain, is to show him [[TalkingInYourSleep talking in his sleep]] (or in a delirium). His speech will usually be remarkably clear and lucid for someone who is out of his conscious mind, but other times what he says is cryptic and its significance has to be pieced together by the rest of the cast. If he sleepwalks, they will catch him doing some activity or ritual related to the cause of his pain.

The instant Bob wakes (often [[CatapultNightmare by bolting upright in bed]]), he will be back to normal. However, dread of more nightmares makes him likely to become TheInsomniac, which can prove dangerous if these are RecurringDreams. If he woke everyone else up with his screaming, he will apologize for disturbing them. Usually. But he also usually won't tell them what made him scream. If he has superpowers then they may [[PowerIncontinence spark and fly about]] as he tosses restlessly, unable to control them as they activate in his fevered state. (Every once in a while this vulnerable moment opens the door for Bob to tell someone else about his trauma; this can be [[EpiphanyTherapy unrealistically beneficial]].) If Bob also suffers from GoMadFromTheIsolation, he will often not be able to remember that he is safe until several moments after waking.

If they stemmed from MyGreatestFailure, Bad Dreams may overlap with AnxietyDreams, and be fixed with it if Bob 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 that Bob is a traumatized character even though he is doing his damndest to hide that fact. (And nightmares from trauma can indeed be TruthInTelevision.)

Being the outward sign of an inward pain, Bad Dreams are obviously more likely for characters who keep their feelings on the inside: the Stoic, the EmotionlessGirl, BrokenBird, and the like (whether Bob hides his pain from everyone or just from one particular person). But they can be a useful tool for demonstrating trauma for -- and humanizing -- anyone, since you can't control your 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 they cannot show weakness in front of their people and [[AFatherToHisMen feels responsible for them]].

YourWorstNightmare may be mistaken for Bad Dreams. When the character suffers from TraumaInducedAmnesia, they can overlap with DreamingTheTruth. 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. The character may not be able to tell that someone is communicating because the means are bringing up memories. May be a FeverDreamEpisode. Contrast DreamingOfThingsToCome and TalkingInYourDreams.

These are often RecurringDreams, at least by implication. May be caused by buried memories from AlternateIdentityAmnesia.

Supertrope of FlashbackNightmare, which shows the nightmare in the form of a {{flashback}}.

Not to be confused with the ''VideoGame/BadDream'' series.



[[folder:Anime & Manga]]
* Eren Yeager from ''Manga/AttackOnTitan'' starts having some rough nights late into the story [[spoiler: as he relives his [[DarkAndTroubledPast father's memories]] in his dreams, triggered by reading the journals in the Yeager basement (don't ask, it's complicated)]]. He's [[CatapultNightmare woken up screaming]] at least once, and for good reason [[spoiler: he saw the AwfulTruth behind the titan that killed his mother.]]
* 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.
* ''Anime/NeonGenesisEvangelion'': Asuka has one right beside [[LoveInterest Shinji]] on their final night of having to 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 ''Manga/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.]]
* In ''Anime/CodeGeass'', Lelouch, Suzaku, and Nunnally all have bad dreams from their experiences as children in a war zone. Around others, they put on a mask of cheerful, ordinary high school students, but when they are alone, this shows. The show uses this to frame some flashbacks as well.
* 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.
* In ''Anime/YuGiOhCapsuleMonsters'', Yugi has a couple nightmares about Yami being captured and the armor they later get being not enough to save him against the Seven-Armed Fiend.
** After he and Anzu survive a train crash in the anime filler arc, Yami has a nightmare/convenient flashback to losing Yugi's soul.
* In ''Manga/OnePiece'', Doflamingo continued having nightmares well into his mid twenties reliving his experiences being [[spoiler:tortured when he was a child by angry citizens. This experience was a result of his father denouncing the Donquixote family as Celestial Dragons, when the ordinary citizens of the country they were living in found this out they rounded them up for torture. Even up to the current story point, Doflamingo continues to loath his father for throwing away his birthright and placing them in that predicament. And even more personal, Doflamingo continued holding such hatred that he poetically named his ultimate attack "16 Sacred Bullets of the Assassin, God Thread" a mocking reference to a man who was part of the mob that tortured him claiming his sons were shot dead 16 times by Celestial Dragons. A subtle glimpse to how badly Doffy still wished his father hadn't denounced their Celestial Dragon status.]]
* In ''Manga/VinlandSaga'', Thorfinn is troubled by bad dreams every night, both shown directly and through his inability to sleep peacefully. These dreams are a mixture of childhood traumas over losing his father and home and his own bad conscience about all the people he has killed.

[[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.
* ComicBook/{{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]].
* Several of the members of the post-''Comicbook/ZeroHour'' ''Comicbook/{{Legion Of Super-Heroes}}'' have recurring Bad Dreams following the "[[ZombieApocalypse Legion of the Damned]]" arc, in which many of them were taken over by [[TheVirus The Blight]].
* At the beginning of the ''ComicBook/{{Bizarrogirl}}'' storyline, which happens right after the destruction of ''ComicBook/NewKrypton'', ComicBook/{{Supergirl}} has nightly nightmares in where she fights Superwoman again, and a legion of corpses tries to drag her down to Hell.
-->'''Supergirl:''' Some people talk in their sleep. Others walk. I heat-vision, apparently.\\
'''Comicbook/LanaLang:''' I'm sure someone out there makes a sleep mask that can handle that. Nightmare?\\
'''Supergirl:''' Yeah... Again.
* In the beginning of ''ComicBook/Trinity2008'', Franchise/{{Superman}}, Franchise/{{Batman}} and Franchise/WonderWoman get together to talk about several strange dreams they keep having night after night concerning a prisoner intent on breaking free.
* Yorick, the protagonist of ''ComicBook/YTheLastMan'', gets these frequently. At one point one of his companions comments that they'd hate to live in his mind.
* 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.
* ''Comicbook/{{Empowered}}'': Basically everyone. Most of the cast is dealing with serious PTSD, with the obvious result.
** Emp herself has nightmares both of her father's death (he had a fatal brain aneurysm right in front of her when she was a kid) and the many, ''many'' times she's been tied up by the bad guys. Her boyfriend often hears her whimpering in her sleep.
** Emp's boyfriend isn't much better. He used to be a {{Cape Buster|s}} leading a [[BadassNormal capeless uprising]] until the San Antonio incident (when he missed getting killed by a newborn supervolcano by less than a mile). He lost a lot of friends during that time, but what he has the most nightmares about is Willy Pete, a "goddamn fire elemental" who raped all his remaining friends to death. Emp often hears him calling out the names of people she's never heard him mention while awake, and his greatest fear is that Willy Pete will one day find Emp herself.
** Ninjette is on the low end of the nightmare scale, but not for lack of a horrific backstory. Her nightmares are more about her fears of the future. Specifically, her father sending her ninja clan to capture her, cut off her hands and feet, and turn her into a breeding sow for the rest of her life. And yes, that actually is his stated goal.
** Mind████ was forced by her brother to [[DisabilitySuperpower cut out her own eyes and tongue]] in an effort to make her a better telepath (by forcing her to piggyback on other people's senses). He was stopped before he could make her deafen herself, but she still relives the event every single night, over and over and over. Worse, [[PowerIncontinence since she can't control her powers while asleep]], these nightmares ''leak'', and anyone nearby sees them in vivid detail. Normally she follows isolation protocols to keep others at a safe distance, but once she accidentally fell asleep in her girlfriend's arms. When they both woke up, she tried to leave, but her girlfriend insisted on her remaining. What followed was the worst night of her girlfriend's life, and she later says that she feels like it was the most heroic thing she had ever done.
* In his first appearance in ''Amazing ComicBook/SpiderMan'' #101-102 ComicBook/{{Morbius}}' backstory is retold through the nightmares he suffers, in which he keeps recounting the scientific accident that turned him into a living vampire and killing Emil immediately after. He is occasionally shown to be reluctant to go to sleep because he knows he'll have more nightmares.

** 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.
* ''Series/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 "[[Recap/DoctorWhoS30E14TheNextDoctor 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.

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 "[[Recap/DoctorWhoS31E7AmysChoice Amy's Choice]]", the Eleventh Doctor's cheerful carefree manner is revealed to be a mask at least some of the time.

* "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.

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 an episode of ''Series/TalesFromTheDarkside'', a gangster is given a chance to dream beautiful dreams for all eternity.

[[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.]]
* ''Franchise/FinalFantasy''
** Cloud from ''VideoGame/FinalFantasyVII'' experiences these regularly over the course of the game (sometimes while he is wide awake).

* ''VideoGame/MetalGear''
** At the end of ''VideoGame/MetalGear2SolidSnake'', 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/MetalGearSolid3SnakeEater'' 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 ''VideoGame/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.
* ''VideoGame/{{Fallout}}''
** 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.
** ''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.
* 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.
* Kratos's motivation to serve the gods in ''VideoGame/GodOfWar'' 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.
* ''Franchise/MassEffect''
** 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 ''VideoGame/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]].

* 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/SakuraWarsTV anime]]] or her love interest [manga]... the original game is unclear on this point), for which she feels responsible.
* ''Videogame/SunlessSea'' also implements nightmares, which will happen if you arrive at London with very high Terror. Notably, these nightmares are a concrete thing (like having nightmares about a vast eye that never stops watching you) rather than ''Fallen London'''s vague Nightmares stat. Having restful nights at home will help in dealing when they come for you at zee, as otherwise they'll shoot up your terror rather quickly.
* ''VideoGame/NiGHTSIntoDreams'' and its sequel ''[=NiGHTS=]: Journey of Dreams'' involve the visitors (the sleeping children) having to overcome these.
* Many interpretations of ''VideoGame/YumeNikki'' hold that the often horrific symbolism in Madotsuki's dreams was inspired by some traumatic event in her past, be it rape, death, the apocalypse, or any other number of theories and abstractions. What is certain is that [[{{Hikikomori}} it's probably not something she's telling many other people]].

* 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''.
* ''VisualNovel/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]].
* In ''VisualNovel/{{Sunrider}} Mask of Arcadius'', after seeing a little girl [[DeathOfAChild get gunned down right before his eyes]], Kayto starts having nightmares in which the girl’s mangled corpse blames him for her death. Later on, the dreams evolve so that the girl morphs into the mangled corpse of Kayto’s sister Maray, who was killed when PACT nuked his home city from orbit.
* ''VisualNovel/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.]]
* In ''VisualNovel/{{Demonheart}}'', the protagonist has recurring nightmares of a tortured demon child begging her for help.

* These happen all over the place in ''WebAnimation/BrokenSaints''. Chapter 7, Lucid, is all about the lucid dreams Raimi's been having.

[[folder:Web Comics]]
* Type Two is the primary way in which the reader learns Lexx's [[DarkAndTroubledPast backstory]] in ''Webcomic/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/IronGate" Embers is plagued by nightmares which can cause her fire powers to activate while sleeping, leaving anything close to her in danger of being burned.
* 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.
* ''Webcomic/{{Metanoia}}'''s Star Tyrian, {{lampshade|Hanging}}d [[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 ''Webcomic/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 ''Webcomic/AdorableDesolation'' wakes up screaming every morning, but he doesn't remember what he's been dreaming about.
* ''Webcomic/BobAndGeorge'': [[http://www.bobandgeorge.com/archives/020306c Megaman has them, apparently]]
* ''Webcomic/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 ''Webcomic/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 ''Webcomic/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.
* ''Webcomic/NinthElsewhere'': Since the story takes place almost entirely in one of the character's subconscious, this trope was inevitable.
* In ''Webcomic/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.]]

* In ''Webcomic/{{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.
* The second day of ''{{Webcomic/Morphe}}'' has the captives [[http://morphe.thewebcomic.com/comics/1790280/chapter-2-page-19-sweet-dreams/ suffering nightmares]] of what happened to them before they woke up at the start of the story.
* The very first page of ''Webcomic/AliceAndTheNightmare'' shows Alice waking up from ''a'' nightmare. Made troubling by the fact that Wonderlanders aren't supposed to have them.
* ''Literature/TheJenkinsverse'' has Xiù Chang, whose dreams are not necessarily *bad* so much as vivid, surreal, and prone to waking her up.
* ''WebComic/StandStillStaySilent'': JustBeforeTheEnd, Árni Reynisson from the prologue works for an Icelandic coast guard that has resorted to bomb refugee boats to stop the spread of ThePlague. The segment focuses on Árni quitting his job because he has been having such dreams.

[[folder:Web Original]]
* ''Podcast/DiceFunk'': Johnny inflicts nightmares on the entire party during their first long rest. Leon refers to them as "cutscenes."
* 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 ''WebVideo/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]].
* Considering how traumatic her entire life is, [[DarkMagicalGirl Himei Shoutan]] of ''Literature/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 Creator/WillSmith [[WesternAnimation/SharkTale fish]] to please leave her nightmares.
* WebVideo/TheNostalgiaCritic states Pauly Shore's [[Film/BioDome creepy laughing]] will be the new soundtrack to his night-terrors for a while. Played more seriously later on, as he has nightmares in WebVideo/ToBoldlyFlee and he keeps waking up with anxiety attacks. In the ''The Sixth Day'' review, apparently this still happens.
* 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 ''Roleplay/TheGunganCouncil'' has reoccurring nightmares reliving the torture sessions under the hands of Azrael Daragon during her time in slavery.
* The Courier in Machinima/CouriersMindRiseOfNewVegas always has nightmares about his mysterious and DarkAndTroubledPast, whenever he goes to sleep. Though, it's played with, as he lives in a CrapsackWorld already and he admits the only real difference is he doesn't have his RobotBuddy in his dreams.

[[folder:Western Animation]]
* Done without seeing the actual dream in ''WesternAnimation/BatmanBeyond'', when Payback calls himself Bruce's worst nightmare, and Bruce simply retorts [[Awesome/BatmanBeyond "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 the 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.
* ''WesternAnimation/XMenEvolution''
** [[TheDragon Mesmero]] uses 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.]]
** Comicbook/{{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 S2 E17, "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 GrandFinale of ''WesternAnimation/CourageTheCowardlyDog'', "Perfect", featured several of these on account of Courage's constant berating from an evil teacher. They're all manifestations of his low self-esteem and yearnings to be perfect, two of which involving bizarre creatures reminding him of such. And these are ''nasty'' dreams, especially the first, more infamous one: a blue deformed humanoid, [[UncannyValley rendered in CGI]], who whispers "You're not perfect." [[note]] Fans also speculate it to be an amalgamation of Eustace's broken bugle and a human being. [[/note]] Watch it [[https://www.youtube.com/watch?v=xFDldk9D_Qc here]], if you dare.
* 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.
