Characters in fiction are imaginary. Now extend the fact that characters that are imaginary within a work of fiction, and you get Dream People. They might be inhabitants of {{Dreamland}} or hallucinations, but that doesn't mean they don't have hopes and fears. If the real characters know about the imaginary nature of the Dream People, they may or may not [[WhatMeasureIsANonHuman stop caring about their well-being]].

Ghosts are [[OurGhostsAreDifferent a separate trope]], while virtual entities are covered by InsideAComputerSystem, ProjectedMan and DigitalAvatar. Compare ImaginaryFriend, IntangibleMan. See also DreamLand and DreamApocalypse.

[[AC:{{Anime}} And {{Manga}}]]
* Most of the [[spoiler:inhabitants of Mars]] in ''Manga/MahouSenseiNegima''. Revealed when they start getting erased.
* The inhabitants of the DreamLand in ''Literature/{{Paprika}}''.
* Possibly the Ijin in ''Anime/ReadOrDie''. Either that or they are [[CloningBlues clones]].
* Princess Adina from ''Anime/YuGiOh'', as well as the other inhabitants of Simlow.
* In ''Manga/FairyTail'', [[spoiler:the entire Cait Shelter guild]] ends up being an illusion caused by Robaul.

* In ''ComicBook/TheAvengers'', [[ComicBook/TheIncredibleHercules Hercules]] falls in love with a woman named Taylor Madison. It is eventually revealed to be an illusionary construct created by Zeus as part of a BatmanGambit to expose his wife Hera's plans to harm his son, knowing that she would [[StuffedInTheFridge target the person Hercules holds most dear]]. Despite his son's pleas, Zeus erases Madison from existence once she has served her purpose, leading to a [[IHaveNoSon violent falling out]] between Hercules and Zeus and the latter revoking his son's immortality.
* ''ComicBook/PoetAndersonTheDreamWalker'' has many in the dream city of Genesis, including Ayo who serves as a guide for the Anderson brothers.
* In ''ComicBook/AstroCity,'' this is a key element of the origin of American Chibi, dreamed into existence by video game designer Marguerite Li. [[spoiler:Chibi is dreamed up by Marguerite after a group of eldritch abominations haunt her with dreams of monsters, and becomes manifest in the real world. This causes the walls between the dream-world and reality to weaken, allowing them to appear in the material world as the monsters from Marguerite's dreams.]]
** The same is true of [[spoiler:the Gentleman]]. His "daughter" created him from idealized memories of her real father, with his KidSidekick being her idea of an ideal older brother. There's also Loony Leo, a cartoon lion brought to life by a MadScientist, whose existence was initially maintained by [[ClapYourHandsIfYouBelieve people's belief in him]].

* [[spoiler:Parcher, Charles and Marcee]] from ''Film/ABeautifulMind''.
* ''Film/{{Inception}}'': The projections of the characters' subconscious in the dreamworld. [[spoiler:[[MindScrew And everyone else.]]]] [[OrWasItADream Maybe.]]

* In ''WesternAnimation/InsideOut,'' the main characters are {{Anthropomorphic Personification}}s of a girl's emotions who live in her MentalWorld. Others also exist there, most notably Bing-Bong, her old ImaginaryFriend. ([[spoiler:He gets a {{Tear Jerker}}y death]].)

* Creator/EdgarRiceBurroughs' Barsoom novel ''Thuvia, Maid of Mars'': The inhabitants of Lothar are able to mentally create illusions of the ancient warriors of the city. One of the warriors is created so often that he becomes real.
* In ''Literature/{{Solaris}}'', the mysterious "visitors" that appear on the ship are [[{{Doppelganger}} doppelgangers]] of the crew members' loved ones.
* ''Literature/AnElegyForTheStillLiving'': The entire cast, even including Francis.
* Tommy Hazzard in ''The Boyfriend List''.
* ''Literature/TheRavenCycle'' has the Orphan Girl and [[spoiler: Aurora Lynch.]]

* Harry Morgan [[spoiler:and Brian Moser]] in later seasons of ''{{Series/Dexter}}'', since the resulting {{Dead Person Conversation}}s are more to different aspects of his subconscious than the actual people themselves.

* Manes in ''TabletopGame/GeniusTheTransgression'' are the inhabitants of pocket realities called [[DreamLand Bardos]]. They're rather fragile outside Bardos.
* ''TabletopGame/ChangelingTheLost'' likewise features Incubi, ranging from simple "background players" to more aggressive concepts, such as Succubi, Night Hags, and a sentient play that convinces the actors to kill each other in a fit of jealousy.

* This trope is EVERYWHERE in ''VideoGame/YumeNikki''. The whole game takes place in the dreams of a young girl, so you should expect some interesting characters. Things like walking clocks, faceless technicolor people, walking whistles, deformed bird witches, pixel sculptures, mouths in wigs, ghosts, candle people, and even some unique characters in between, all haunt the regions of the game.
* The strange beings of ''VideoGame/LSDDreamEmulator'' (naturally), especially the mysterious Grey Man who [[ParanoiaFuel intermittently appears from thin air and drifts toward the screen]], waking you up if it catches you.
* In ''VideoGame/DragonQuestVI'', the inhabitants of the DreamLand.
* [[spoiler:Tidus and the other inhabitants of Zanarkand]] in ''VideoGame/FinalFantasyX''.
* [[spoiler:The inhabitants of Magicant, excluding Queen Mary]] from ''VideoGame/EarthBoundBeginnings''.
* In ''VideoGame/TheLegendOfZeldaLinksAwakening'', it turns out that [[spoiler:everyone except]] Link is just a dream of the Wind Fish.
* Agent Francis York Morgan from ''VideoGame/DeadlyPremonition'' has an invisible friend named Zach. Zach acts as a stand-in for the player; whenever York addresses Zach, York is speaking through the FourthWall. The in-game explanation is a bit more [[MindScrew complicated]].
* Part of VideoGame/TheDreamMachine takes place inside dreams. The only people you can interact with for the majority of these sequences are examples of these.
* Depending on the [[OrWasItADream interpretation]], practically everyone in ''VideoGame/EternalSonata'' is one of these. The entire world as well as its inhabitants exist in a world based almost solely around music, which presumably only exists as Chopin's DyingDream. Though as time goes on, even he begins to question that conclusion.

* Zimmy's mental constructs in ''Webcomic/GunnerkriggCourt''. Disconcertingly, they're ''not quite'' people; their faces are scribbles that vaguely resemble QR codes, [[{{Dissimile}} except not]].
* ''Webcomic/NinthElsewhere'': Carmen's dreamscape is inhabited by figments, each of which represents a different aspect of her personality.

* In the ''WesternAnimation/PoetAndersonTheDreamWalker'' short film, the coal shovelers on the train are the only characters who show up that aren't defined in some way as Dreamers.
