History Main / MentalWorld

* In TroperWorks/HumanOfTheOtherSide, the character Raim Hanta's mind has reproduced several location of Japan he has visited. However, inside of it, sometimes a weird crossbreed between TheHeartless and light doses of PsychologicalHorror, appear in order to kill him and/or screw his mind. The laws of physics there are fairly normal, but then he figures out he can walk over the surface of buildings. Oh, and there's a bridge which [[TengenToppaGurrenLagann spirals up to the heavens]]. Damn his mind is messed up.
* [[FanFic/ToyHammer]] has the 'mindscapes' which seem to be a Mental World mixed in with Forge Mode of Halo; characters can create and use weapons, buildings and whatever they wish to create and fight in this manner. Used to its full extent with weapons being thrown away in favor of creating new ones, buildings being used in miniature {{ColonyDrop}}s and a literal wall of Gatling guns for... [[CurbStompBattle crowd control]].

!!Examples

* ''{{Earthbound}}'' has Magicant.

* Orion from BeyondReality is in his own in the current story arc, and it looks like it may be leading to a BattleInTheCenterOfTheMind.

See also JourneyToTheCenterOfTheMind. Tends to be a {{Wackyland}}, especially when exploring one's personal mind. Not to be confused with WombLevel.

** In ''{{Tsukihime}}'', {{canon}} has that it that in Yumizuka Satsuki's ([[IsntItSad nonexistent-but-eventually-will-exist]]) route she has her own Reality Marble representative of her continuous loss-without-gain called ''Depletion Garden'', which sucks all the mana in the surrounding area dry (of course, it doesn't really benefit her directly).

* ''ArTonelico'' have Cosmospheres, Infelsphere and Fusionspheres, the first is located within every reyvateil's mind, the hero will do an activity called ''diving'' inside the reyvateil's cosmosphere, to solve their inner problems.

* All the weapons in ''Soul Eater'' reside in an infinite black space ([[OutOfClothesExperience naked]]) when in their weapon forms, which can be seen from outside as uncanny reflections on their metallic surfaces. Soul Eater (a sinister partly collapsed cavern,) Tsubaki (a serene marshy lake,) her brother (a burnt down forest,) and Crona (an empty desert or a pretty beach, depending on how withdrawn they are) also all have more distinct and empathic mental worlds. Soul Eater also has [[BlackBugRoom a red and black room in his mind]], where he appears in a pinstriped suit [[EnemyWithin accompanied by an imp]].
* In '{{Bleach}}', Ichigo's Mental World is a city of skyscrapers… and gravity is at right-angles to normal, meaning that he fights his mental Battles standing on the sides of the buildings…

* ''{{Soul Eater}}'' has several examples.
** Soul's soul is depicted as a red and black decorated room with a piano in it. This may or may not be down to his having been infected with the black blood (we see it only after the Italy episode, but he has a longer history with the piano and what it seems to represent for him).
** Tsubaki's soul changes between a dark world filled with long, looming shadows and a clear blue sky over water, depending on whether or not the Nakatsukasa Purpose is involved and how its being used.
** When the Weapons are transformed, they seem to be in a black, empty space. Liz and Patti seem able to actually move around (Patti on one occasion turning up on Liz's 'side').
** Crona's soul is depicted firstly as an empty desert in which Crona is sitting in circle, where their insane/sad side is shown as a shadow. When Maka enters her soul and convinces Crona (both represented as young children) to leave the circle, the desert is replaced by an island with a blue sea surrounding it. The anime later uses this imagery when Crona runs out of Death City into an actual desert and somehow ends up in a big hole.

* All the weapons in ''Soul Eater'' reside in a black space when in their weapon forms. Soul Eater also has a red and black room in his mind, in which he appears wearing a pinstriped suit.
* In '{{Bleach}}', Ichigo's Mental World is a city of skyscrapers... and gravity is at right-angles to normal, meaning that he fights his mental Battles standing on the sides of the buildings...
** ... except when he's about to become a Hollow, then gravity rights itself and the buildings begin dissolving.

* The dungeons in ''{{Persona4}}'' are created from the subconscious of the people who were kidnapped.
* In {{Shadow Hearts}} first and second, Yuri's Mental World is a [[spoiler:graveyard, where monsters embodying his flaws and fears roam, waiting for him to fuse with their souls]]. It has an actual influence on the real world, as [[spoiler:it finally digests Alice's soul]].
* One key aspect of {{Silent Hill}} is the blurring between the physical world and the MentalWorld of a powerful psychic. Also many of the monsters that appear in the town take shapes directly related to the personal fears and troubles of the protagonists [[spoiler:and in the case of Maria, can only be explained as creations of the protagonists mind]]. In SilentHill 4, the main character is jumping across a number of an undead serial killer's memories.
* With Alma being an almost copy of Alessa of Silent Hill, the last fight in [[FirstEncounterAssaultRecon FEAR 2]] takes place in a MentalWorld, which is a bleak and chaotic as one would expect.
* YumeNikki centers on exploring the [[NightmareFuel very unsettling]] dream world of an (apparently) very disturbed little girl.

[[AC:TabletopGames]]
* ''{{Warhammer 40000}}'''s Warp is a collective MentalWorld of the dreams and emotions of every sentient creature in the galaxy.
** It's also the only afterlife and home to 4 Chaos Gods([[MyFriendsAndZoidberg plus a few more]]) & an arbitrarily large number of demons.
*** That's mainly because most sentient creatures in the galaxy don't have very much [[ThePowerOfLove love]] or [[ThePowerOfFriendship friendship]].
*** The Chaos Gods actually reprsent both positive and negative emotions, just taken to the extreme. Since they gain power from the emotions, they want their followers to feel as strong emotions as possible. So the deamons of the god of love rape you to death.
** Also home to the Ork gods Gork and Mork, the psychic manifestation of the Ork race. Given that the Orks vast numbers and simple mentality (endlessly enthusiastic and no real concept of defeat or despair), Gork and Mork appear to be invunerable and portrayed as simply laughing off any attacks by Chaos gods. Fortunately for everyone else they seem to have no plans other than cheering on the Orks and bashing each other over the head.
* In TheWorldOfDarkness, both Mages and Changelings can travel into, and [[RealityWarper warp]] both their own dreams and the dreams of others.
** Mages can go further beyond the mere subconscious and into a person's Oneiros (one of the three Astral Planes), which is their own soulscape. It contains the AnthropomorphicPersonification of their desire for self-improvement, their darker urges, their fears, and their Flaws and Derangements (if they have any). It also contains the sum total of all a person's knowledge and experience, albeit shrouded in metaphor and symbolism (or in the case of memories, the subjectivity of the experience). Its possible to travel even deeper into the Tenemos, which is the [[DreamWorld collective unconscious of humanity]].

* AmericanMcGeesAlice has Alice fighting in [[DreamWorld Wonderland]] - a world that represents her mind. Given that at the time Alice is in an asylum, Wonderland is virtually a [[HighOctaneNightmareFuel nightmare]], twisted by her insanity and depression.

[[AC:{{Anime}}]]
* ''{{Paprika}}'' based on Yasutaka Tsutsui's 1993 novel of the same name IS this trope.
* In the memorypunk universe of ''{{Kaiba}}'' a relatively common device is utilized which allows one to literally step into the mind of another person or simply click through their memories like a slideshow.
* In the {{Nasuverse}}, this is used as a powerful rare ability called a ''Reality Marble'', where the user can temporarily overwrite the surrounding reality with a landscape representative of their soul/meaning.
** ''[[FateStayNight Fate/stay night]]'' had this as a major plot point, as the only thing that Archer [[spoiler:(and Shirou, by extension)]] truly gained in his lifetime was his [[FieldOfBlades Reality Marble, Unlimited Blade Works]], an endless, barren landscape littered with swords. It's the basis behind all of his techniques - all of the weapons he recreates come from this world of his, which is representative of his lifelong conflict between ideal and reality.
** Iskander, aka Alexander the Great, in ''[[FateZero Fate/Zero]]'' possesses the 'shared' Reality Marble "Ionioi Hetairoi" ("Army of the King"), which recreates the battlefields of his past and resurrects his army, many members of which have become Epic Spirits themselves, but comes at his call even after death. It is this display of kingship that finally forces Gilgamesh to recognize him as a WorthyOpponent.
** In ''{{Tsukihime}}'', {{canon}} has that it that in Yumizuka Satsuki's ([[IsntItSad nonexistent-but-eventually-will-exist]]) route she has her own Reality Marble representative of her continuous loss-without-gain called ''Depletion Garden'', which sucks all the mana in the surrounding area dry (of course, it doesn't really benefit her directly).
*** The term "Reality Marble" ("Innate Bounded Field" in Japanese) comes from a metaphor. In a bag of a hundred marbles, 99 are black and one is white. "Marble Phantasm" is the ability of spirits or elementals to changing the probability of picking the white one to 100%; "Reality Marble" is the unnatural ability to turn all the marbles white.
** Also Kagetsu Tohya for a non Reality Marble example. That would be spoilered considered it's part of TheReveal midstory... but it's kind of obvious.
* In ''RozenMaiden'', everyone's dream worlds are connected through the WorldTree. Somewhere inside any given person's dream world is a tree that represents that person's mental and emotional well-being.
* All the weapons in ''Soul Eater'' reside in a black space when in their weapon forms. Soul Eater also has a red and black room in his mind, in which he appears wearing a pinstriped suit.
* In '{{Bleach}}', Ichigo's Mental World is a city of skyscrapers... and gravity is at right-angles to normal, meaning that he fights his mental Battles standing on the sides of the buildings...
** ... except when he's about to become a Hollow, then gravity rights itself and the buildings begin dissolving.
* In {{Naruto}} the main character oftentimes finds himself inside of his own mind, face to face with the [[SealedEvilInACan Kyuubi]] for which his body serves as the container.
** Also one of the abilities of the Mangekyou Sharingan is the ability to trap an enemy's mind in a mental landscape complete with [[WhatDoYouMeanItsNotSymbolic crosses and a weird red moon]], in which time is altered so that days pass over the course of seconds.
* Negi of ''MahouSenseiNegima'' was once trapped in his own Mental World represented by the ElaborateUniversityHigh he teaches at with his SinkOrSwimMentor Evangeline slaughtering him for days in a world he can't completely die in. This was required to unlock his DeadlyUpgrade. A bit of [[PsychicNosebleed physical]] BloodFromTheMouth was in order.
* MadScientist Dr. Kanzaki from BlackCat has the tao power of "Warp World", which creates one of these. He has total control over the contents and the senses of the people within.
* Yugi of ''[=~Yu-Gi-Oh!~=]'' features this in his Millenium Puzzle where the mind of Yugi is separated into two worlds, one which is like a toyroom to symbolize Yugi's naivete and innocence as well as his love for games while the other is a mishmash twist of traps, mazes and plains that defy the laws of physics to symbolize the depths of Atem's soul. To note though, if you fall to one of Atem's traps in the area, even if he did not want to kill you, you can still end up brain dead.
** One issue of the manga also showed Anzu's mental world, which was filled with things that emphasized her dreams of becoming a dancer.
* There's a few of these in ''ChronoCrusade'', mostly shown when Rosette "dives" [[JourneyToTheCenterOfTheMind into a person's soul]]. Azmaria's world looks like a graveyard in pouring rain (although it's possible this was influenced by the demon possessing her at the time). Chrono's looks like the grave he was sleeping in when Rosette found him. It's also possible that Rosette's is a train, but [[spoiler:given what was happening when we see her there, it's quite likely that was just her world's version of Purgatory.]]
* In {{Psyren}}, LovableCoward Kabuto's powers are derived from a mental world, where a subconscious creature named Yoyo resides.
* Similarly to the ''BlackCat'' example, Road Kamelot in ''[=~D.Gray-Man~=]'' can draw people's minds into a world where she has total control. The one time we've seen her use it, she {{Mind Rape}}d [[spoiler:Lavi by confronting him with his BecomingTheMask]].
* ''{{Soul Eater}}'' has several examples.
** Soul's soul is depicted as a red and black decorated room with a piano in it. This may or may not be down to his having been infected with the black blood (we see it only after the Italy episode, but he has a longer history with the piano and what it seems to represent for him).
** Tsubaki's soul changes between a dark world filled with long, looming shadows and a clear blue sky over water, depending on whether or not the Nakatsukasa Purpose is involved and how its being used.
** When the Weapons are transformed, they seem to be in a black, empty space. Liz and Patti seem able to actually move around (Patti on one occasion turning up on Liz's 'side').
** Crona's soul is depicted firstly as an empty desert in which Crona is sitting in circle, where their insane/sad side is shown as a shadow. When Maka enters her soul and convinces Crona (both represented as young children) to leave the circle, the desert is replaced by an island with a blue sea surrounding it. The anime later uses this imagery when Crona runs out of Death City into an actual desert and somehow ends up in a big hole.
* ''{{Code Geass}}'' has the [[spoiler: World Of C, the world that is the link between Human Consciousness (including the memories of the dead) and the waking world]] which has a link to Geass... that no one ever explains, or possibly even knows about.
** Also, there's the White World, a mental world that C.C. and Lelouch appear in once, butt naked, while their minds are linked or something...
** And finally, C.C.'s World of Memories. When [[spoiler: C.C. locks away her own code, she buries herself in a world filled with paintings that represent her memories... with some sort of caretaker C.C. walking around.]] Which, again, never explained, though I suppose the concept is common enough for people to understand.
* Shinji from ''NeonGenesisEvangelion'' frequently lapses into a hallucination of himself sitting in a commuter train at sunset. He's usually accompanied by a child version of himself sitting in front of the sun though at later points he sees Rei instead; sometimes he sees both at the same time with Rei standing to his left. The topic of conversation is always piloting. In ''End of Evangelion'', he gets both Rei and Asuka at the same time: Rei sitting in her usual seat and Asuka standing right in front of him, one leg propped up onto his seat.
** While he's swallowed up in his Eva, he gets a radically different and very vivid hallucination implied to have been caused by Yui.
** And of course there is the original depiction of Instrumentality: the subject of the hallucination sitting in a chair, surrounded by various people while they mercilessly dissect his/her personality.
* In the TV series of RecordOfLodossWar, Neese has to fight the spirit of Naneel within her own mind, over control over their shared body.

[[AC:TroperWorks]]
* In TroperWorks/HumanOfTheOtherSide, the character Raim Hanta's mind has reproduced several location of Japan he has visited. However, inside of it, sometimes a weird crossbreed between TheHeartless and light doses of PsychologicalHorror, appear in order to kill him and/or screw his mind. The laws of physics there are fairly normal, but then he figures out he can walk over the surface of buildings. Oh, and there's a bridge which [[TengenToppaGurrenLagann spirals up to the heavens]]. Damn his mind is messed up.

* The Attic in ''{{Dollhouse}}'' is revealed to be a long chain of nightmarish MentalWorld scenrios chained together to be a giant super computer.

* All the {{Silent Hill}} games may count, but SilentHill 4 is the most obvious, with the main character jumping across a number of an undead serial killer's memories.

* Orion from BeyondReality is in his own in the current story arc, and it looks like it may be leading to a BattleInTheCenterOfTheMind.

* Yugi of ''{{Yugioh}}'' features this in his Millenium Puzzle where the mind of Yugi is separated into two worlds, one which is like a toyroom to symbolize Yugi's naivete and innocence as well as his love for games while the other is a mishmash twist of traps, mazes and plains that defy the laws of physics to symbolize the depths of Atem's soul.
