->''A computer chattered to itself in alarm as it noticed an airlock open and close itself for no apparent reason.\\
This was because reason was, in fact, out to lunch.''
-->-- ''Literature/TheHitchhikersGuideToTheGalaxy'' (the novel)

As far as we know, reality is pretty much fixed[[note]]{{Postmodernism}} notwithstanding[[/note]]. We don't randomly sprout limbs, float into the air, or turn into foot stools. Not so here. There is an area, or at least a circumstance, of the setting that throws the laws of physics in the air and plays merry hell with the established rules of reality. This is not always as funny as it sounds; remember, the same laws of reality that keep your friend from spontaneously turning into a camel are also the same laws of reality that keep your lungs on the ''inside'' of your body. As such, regular exposure is not recommended, as you may get...[[BodyHorror altered]].

Sample conditions of a place where reality is out to lunch include AlienGeometries (constant relation [[YourHeadASplode between skull volume and its surface]] is a good thing to have) and [[YearInsideHourOutside time dilation]][[note]]Except for Relativity physics. Reality is perfectly real in that case[[/note]]. PerspectiveMagic is another common trick. A RealityWarper has this as a superpower. Related to HyperspaceIsAScaryPlace, only the place in question isn't necessarily used for travel purposes. See also EldritchLocation, where this often happens, and WorldOfChaos for when the effect is so widespread it makes up the whole of existence. May result in someone GivingUpOnLogic. Fairly common, or at least not out of the ordinary, in SurrealHorror.



[[folder:Anime & Manga]]
* If upset, LightNovel/HaruhiSuzumiya can unwittingly create "Closed Space", which looks pretty much like copies of parts of the real world, minus people plus large scary rampaging blue {{Kaiju}}-like things. Within said Closed Space, espers can also generate energy fields they can't otherwise generate in the real world. Also, she can also unknowingly [[RealityWarper warp some aspects of the real world]] (like making pigeons into doves, allowing cats to talk, giving people eyebeams, ''or literally turning someone into Santa Claus'') while not affecting the rest of the world at large. Actions by the rest of the main cast usually revert such changes relatively quickly.
* In the void between worlds between Earth and the Digital World in ''Anime/DigimonTamers'' the cast are wandering the dark void wondering what's going on. Then Jeri mentions that "she thinks that way is 'down'". Renamon: "... oh dear." Gravity comes into being and they begin falling.
* Several settings in ''Anime/PrincessTutu'' are like this [[spoiler:since they were created by [[RewritingReality Drosselmeyer]]]]. Humans are spontaneously transformed into talking animals on a regular basis (leaving many confused due to the glamour failure). There's a lake that can become solid and then turn into water again, another that functions like water but allows characters to breathe, and a separate reality that includes talking puppets and a crank to turn back time.
* ''LightNovel/RentalMagica'' has "[[RealityIsOutToLunch Magi Night]]" whenever magical crap hits the {{Ley Line}}s. That a version of this, weakened ''a lot'', is used as an exam in a WizardingSchool should tell you something. Calling it a survival test was a slight exaggeration, but it was a good guts test. [[spoiler:Or it should have been, but our intrepid heroines weren't going to settle until they found the source--and trying to close the faucet, broke it open. Of course.]]
* The witch labyrinths in ''Anime/PuellaMagiMadokaMagica'' seem to put significant portions of reality aside in favor of the whims of the local witch. While inside one of these, you might get attacked by evil cotton balls and flying scissors, or [[BodyHorror stretched and warped far beyond what your body could normally sustain without ripping apart]]. Or that tiny creature you just shot to death could [[spoiler:contain a snake much larger than itself, and this topology-defying snake could leap out and devour you.]] [[IHaveThisFriend Hypothetically.]]
* Ichijou in ''Anime/PaniPoniDash'' appears to have an 'understanding' with reality, leading to it going on lunch break whenever she's around. Very much PlayedForLaughs.

[[folder:Comic Books]]
* ''ComicBook/TheInvisibles'' arc "Entropy in the UK" has the Conspiracy summoning a [[EldritchAbomination big-name horror]] into their base. As a result, the laws of physics go completely random and insufficiently protected characters start developing skin cancer. One psychic character describes trying to read the base as "feel[ing] like someone threw up in my head."
* In the MarvelUniverse, this is the consequence of trying to use [[ComicBook/TheInfinityGauntlet the Reality Gem]] without the other five Infinity Gems (Time, Space, Soul, Power and Mind) there to act as control rods.
* In ''ComicBook/PS238'', time spent in one of these zones results in Cecil getting wings and a number of EldritchAbomination attributes.
* RealityWarper supervillain Proteus from ComicBook/{{X-Men}} comics, particularly "The Day Reality Went Wild". His powers are especially traumatizing for Wolverine, whose heightened senses give him a greater awareness of reality, and a consequently greater awareness of reality being raped.
** Doom pulled the same trick on Wolvie by having him trapped in a room full of optical illusions meant to keep him disoriented. One gets the impression Claremont just liked screwing with his heroes.
* In ComicBook/CaptainBritain, the [[RealityWarper reality-warping]] Mad Jim Jaspers' brief but nightmarish rule over Britain resulted in this; had the Fury not stopped him, it would have spread not only to the rest of the world, but to the entire multiverse.
* In ''Harry Kipling (Deceased)'', the gods chucked out the laws of physics because they aren't mythic enough.

[[folder:Fan Works]]
* ''FanFic/HarmonyTheory'': The Everstorm induces insanity, creates illusions, moves locations, has variable gravity, logic defying weather, attacks with floating skulls and the occasional crucified zombie ursa major animated by fast growing vines among other things.
* Just as its [[VideoGame/{{Stalker}} original inspiration]], ''[[https://www.fanfiction.net/s/8512815/1/TROTTER-Shadow-of-Cheernobyl T.R.O.T.T.E.R., Shadow of Cheernobyl]]'' takes place in the Zone of Desolation, where even the laws of the ''WesternAnimation/MyLittlePony'' universe do not apply. The weather changes on its own, the area is filled with physics-defying anomalies, magic is nearly useless, and [[EverythingTryingToKillYou every single animal is violent]]. It gets [[SurrealHorror even]] [[EldritchLocation weirder]] the closer to the Cheernobyl power plant the characters get.
* Part of the premise of FanFic/TheInfiniteLoops is that the multiverse is damaged, which necessitates the eponymous loops. This means minor glitches occur semi-frequently, and occasionally a loop will run that just makes no sense whatsoever.

* The Infinite Improbability Drive from ''Franchise/TheHitchhikersGuideToTheGalaxy'', which moves the ''Heart of Gold'' vast distances by working from the assumption that the ship has a chance of existing in every place in the universe, then narrowing down the probability so that it merely exists at the plotted destination. When Ford and Arthur are first picked up, they end up in an area improperly shielded from the effects of the drive, and HilarityEnsues as Ford turns into a penguin while Arthur loses his limbs.
** And then there's [[MindScrew horrid fish storming out of the sky, five wild event maelstroms spewing up pavement, the highest prime number hiding itself forever, flying horses carrying reinforced railings, huge children bouncing along the Southend seafront, a million-gallon vat of custard, a team of seven three-foot high market analysts,]] [[MonkeysOnATypewriter and an infinite number of monkeys who appear to have written]] ''Theatre/{{Hamlet}}''.
** Arthur unwittingly exploits this effect later. When [[spoiler:a pair of missiles are fired at the ''Heart of Gold'', he activates the Drive without enabling the probability screens, and the missiles are most improbably transformed into [[ChekhovsGunman a bowl of petunias]] and a very surprised whale. The bridge of the ''Heart of Gold'' gets some redecoration as well]].
** "Reality is frequently inaccurate."
* ''Literature/{{Discworld}}'': Reality is so malleable that things like this are not entirely out of the ordinary. It's actually stated at some point that the trick to breaking physical laws is to get this to happen and then get away with it before the universe remembers that what you're doing is impossible.
** Also, in areas devastated by past magic wars or where residue from magical experiments was dumped, random distortions in reality are commonplace and troublesome. Such areas are known as "unreal estate".
** And some realms--like Death's abode or the tower of the Tooth Fairy--have problems with basic essential laws, like time. Or space. [[spoiler:Or even death...kinda]].
** From the magical battle during ''Discworld/{{Sourcery}}'': "[[TastesLikePurple It looked like a piano sounds after being dropped down a well. It tasted yellow, and felt paisley. It smelled like a total eclipse of the moon]]. Of course, closer to the tower, it got ''really'' weird."
** Perhaps especially notable is how Unseen University uses Hex; knowing that many impossible things are in fact possible ''until'' reality notices, they can use a half Magitech, half BambooTechnology computer to violate the laws of physics in very many ''extremely'' similar but distinct ways, very quickly, too quickly for the universe itself to adjust!
** The Ramtops in general are known for harboring high levels of ambient magic, even by Discworld standards. Rains of fish and two-headed calves are so commonplace that locals [[UnusuallyUninterestingSight dismiss them with]] "Oh, bother, ''another'' bloody portent!" As seen in ''Discworld/WyrdSisters'', it's only when the portents ''stop'' happening that they get worried.
* Some of Boris Vian's works are textbook cases. ''Literature/FrothOnTheDaydream'' (''L'Ecume des Jours'', literally "The foam of the days") has expanding and shrinking windows and houses as well as a water lily growing in Chloe's lung and ultimately killing her.
* Creator/ChinaMieville's ''Literature/BasLagCycle'' has the Cacotopic Stain, an area of desert (well, it's desert ''now'') which is completely consumed by a Torque storm, and Suroch where New Crobuzon dropped a "torque bomb" in a past war. The way they're described, they're part nuclear wasteland, part half-opened door to the abyss.
** Then there's the Scar, in the Swollen Ocean, where long gone reality altering beings once entered the world and 'broke it'. What actually happens there is unknown to the main protagonist, [[spoiler:but a person who goes missing returns from an alternate timeline claiming that he saw everyone fall into a massive chasm into the bowels of the earth. The protagonist has several theories as to whether this was a hoax or not, but quits that line of reasoning in disgust]].
* The LandOfFaerie of ''Literature/TheDresdenFiles'' is a spiritual realm where the [[YearInsideHourOutside flow of time]] is subject to the whims of its Queens, where gunpowder or fire stop working sometimes, and where dying in the wrong place can cause global warming or a fresh ice age. And Faerie is just one of the realms of the Nevernever, which contains [[AllMythsAreTrue every mythological location]], somewhere within it. Faerie is closest to the physical world, and it's suggested that further realms are even less based in normal reality.
** Then there's whatever lies ''beyond'' the Nevernever. So far, it hasn't made many appearances in the books, but things from it have--the Outsiders (EldritchAbomination types who are extremely resistant to magic) and mordite (a material that is basically calcified death). [[spoiler:Faerie and TheFairFolk exist in part to protect the physical world from Outside.]]
* Creator/RogerZelazny:
** In ''Literature/TheChangingLand'', the land around Castle Timeless is currently inhabited by the "mad" demi-god Tualua. Tualua is undergoing one of the "changes" common to his kind, which in this case causes the land surrounding the castle to be subject to all sorts of chaotic, unpredictable, and often-deadly effects.
** In the same author's ''Literature/TheChroniclesOfAmber'', an Amberite can travel to any Shadow (aka parallel universe) they can imagine by simply visualizing the changes they desire as they move. At one point, Merlin is dosed with very strong hallucinogens. It...goes badly. (Even just regular Shadow travel can end in this situation if it's taken out far enough towards Chaos.)
* Creator/JackVance's short story "The Men Return" takes place AfterTheEnd, when the solar system has entered a vast "pocket of non-causality" and the law of cause and effect has crumbled into chaos. A few sane survivors struggle to stay alive in a world where the landscape and circumstances shift randomly around them like a Salvador Dali painting, while the lunatics have adapted to the madness and thrive in it. By the end of the story, the Earth's emerged into normal space again, the insane behavior that'd kept the madmen alive is now useless and self-destructive, and the sane men begin to violently retake the world.
* There's a short story that begins with a quote from Saint Augustine. ''GodIsDead, God is dead--perfidy! When God dies, you'll know it!" As it turns out, the deity just expired, and the world was formerly controlled by the strength of his belief. Now it's a variant of ClapYourHandsIfYouBelieve--and most of the world didn't believe in itself enough to keep existing.
* Most of the world is like this after WorldWarIII in ''Literature/TheGoneAwayWorld''. The "Stuff" left behind goes one step beyond ClapYourHandsIfYouBelieve--it becomes whatever you're thinking of, or, if you get coated in it, makes you whatever you're thinking of, [[BodyHorror regardless of whether you know enough anatomy to survive the transformation]]. The Jormungand corporation has been slowly rebuilding--[[spoiler:[[PoweredByAForsakenChild people with rare brain damage think of Stuff as dust and only dust]], but Jormungand [[HumanResources keeps having to damage more brains]] as the people previously collected die of their injuries]].
* In ''Literature/TheBlackCompany'' novels, there's an area where this is caused by a God brought in from another world. A bunch of stuff got dragged with it and made the best of the situation. There are giant airborne whales, talking and moving menhirs, and lightning-shooting flying stingrays.
* In ''Literature/StormThief'' by Creator/ChrisWooding, the "horror" version of this is played with: probability storms happen all the time, at random, with no warning, and can change ''anything''. If you get caught in one, it can do anything to you, like change the color of your eye-shadow or give you a terminal case of cancer. Of the novel's two main characters, Moa is an orphan because of this and Rail is forced to wear respirator constantly. The city also has barely any technology because the storms turned off all the power and it was hundreds of years before they turned it back on again. The kicker? [[spoiler:This was done ''on purpose'' to keep the city from stagnating into a cruel dictatorship. It does anyway]].
* Happens in ''[[Literature/IntoTheLookingGlass Claws that Catch]]'', when the ''Vorpal Blade'''s chaos drive interacted with the chaos-based shield of a giant derelict, producing a bizarre effect the crew dubbed "the {{anime}} zone". Mostly it involved massive {{flanderization}} of the appearance of the ship and crew, as well as the crew's personalities.
* This has started happening in All-World, the main setting of ''Franchise/TheDarkTower'', due to the Beams that support the titular tower failing. Resulting in time and space beginning to 'drift', what was east one morning may be north-east the next, the passage of time becoming uncertain, etc...and while it's All-World that is the most effected, due to it being the closest to the Tower, as the strength of the Beams continues to decay this would spread to every world.
* Creator/GregBear gives us a particularly [[NightmareFuel nightmarish]] case of this in ''The City at the End of Time''. The Chaos is effectively a new universe running on new rules. But the new rules are either incomprehensible to anything that can exist in the normal universe, or constantly changing, and it's eventually implied that they're ''both''. Creatures from our universe need specially designed armor generating a field of reality just to be exposed to it. Even so, they can only see because the armor converts the nearest equivalent it can find into light, and they have to be constantly on the lookout for...[[DeathWorld pretty much everything]].
** Once the Chaos starts actively trying to kill its visitors, this gets worse still. One example sees characters running for their life, chased by future versions of themselves from the possible future in which they did not get away from their future selves, and were instead dragged by them into the stable time loop they are trying to avoid. [[MindScrew Yes, that bad]].
** In ''Literature/BloodMusic'', the [[spoiler:megaorganism/noocyte collective that used to be the United States]] start observing reality so hard that it starts to perceive new laws of physics which the rest of the planet are unaware of. This in turn stretches local earth reality like a rubber band, and when [[spoiler:the collective decides to AscendToAHigherPlaneOfExistence]] it snaps back so hard that the rest of humanity has to live like stone-age people, since the only reliable means of generating power is by burning wood. [[spoiler:At least until they come back...]]
* In ''Literature/SpaceMarineBattles'' novels, xeno temples and daemon worlds alike have a bad habit of wrapping time and space around them like a scarf. AlienGeometries and YearOutsideHourInside abound. In one Salamander story, an Eldar in cryostasis has found a way to use its power to control gravity outside, wrecking a Terminator team that was coming to poison him.
* The Zones in ''Literature/RoadsidePicnic''. Aliens are weird like that.
* ''Literature/SecondApocalypse'': Topoi are places where a great deal of suffering has taken place, causing the border between reality and Hell to wear thin. Those who go there may at best suffer from horrible nightmares and at worst become physically mutated. One character grows an eye in his heart.

[[folder:Live-Action TV]]
* In the ''Series/StarTrekTheNextGeneration'' episode "Where No One Has Gone Before", the Enterprise is transported to the Outer Rim of the universe, where reality breaks down and starts making crew members' memories real.
* The Delphic Expanse in ''Series/StarTrekEnterprise''. In some parts of it, the known laws of physics did not seem to apply. Once a Klingon ship emerged from the expanse with its entire crew anatomically inverted, but still alive.

* Younger Brother has an album called ''The Last Days of Gravity''. The left side [[http://dailydecibel.files.wordpress.com/2010/07/the-last-days-of-gravity-by-younger-brother_mijqilho-wgx_full.jpg album art]] depicts a man walking into a street corner. The right side has giant scissors walking the streets.

[[folder:Tabletop Games]]
* The Wyld from ''TabletopGame/{{Exalted}}''. Those who live too close to it develop mutations, some of the things that exist within literally cannot exist in reality, and travel time is measured not in terms of distance but by [[TheoryOfNarrativeCausality where you are in the story]]. Oh, and if that weren't enough, TheFairFolk live there. Some other examples of Wyldlife are 'grass with fangs', and the delicious yet nutritious 'Rockodile'.
* The Chaos Wastes, or anywhere sufficiently exposed to the Chaos Winds, from ''TabletopGame/{{Warhammer}}''. Bathed in energy from the same creepy otherspace that plays home to the setting's [[CosmicHorror Cosmic Horrors]], those who spend a good amount of time there usually end up mutating horribly... if they're not already eaten by all the other flora and fauna that's already mutated horribly.
** And in ''TabletopGame/{{Warhammer 40000}}'', you get the [[NegativeSpaceWedgie Eye of Terror.]] Trust us - ''it lives up to the name.''
* ''TabletopGame/NewWorldOfDarkness''
** The Abyss from ''TabletopGame/MageTheAwakening'' is pretty much established as "anti-reality." No one actually goes in there, [[CosmicHorror but plenty of things come]] ''[[CosmicHorror out]]'' [[CosmicHorror of there]]... Well, OK, a few go in, it's just that they don't come ''out''. Unless they happen to be Archmages, and even then, they can only go in for a short while.
** The Abyss also gives rise to the Nemesis Continuum, a set of warped physical laws that create a zone where things work ''wrong''. If you enter a Nemesis Continuum area wearing something green, it'll immediately hit 100 Celsius and give you horrible burns.
** And then there are the Lower Depths. If the Abyss is "anti-reality," then the Lower Depths are "lack of reality" - a ever-shifting series of planes where at least one of the Arcana (such as Death, or Life, or Mind, or Fate...) is missing entirely.
** Faerie/Arcadia from ''TabletopGame/ChangelingTheLost'' is a much better example. Like the Wyld, it serves as home turf for TheFairFolk, and everything within its boundaries is defined not by physics but by contracts and pledges (for instance, if you haven't agreed to let fire warm you up, you can stand in the middle of an inferno and not feel any heat -- though you will get burned). Not only does time work on the YearInsideHourOutside principle according to Earth, but it works ''both ways'', meaning ten days on Earth could pass in three years' time in Arcadia, or vice versa (and those are ''not'' fixed values). Also, those of the aforementioned Mages that control Time and Fate may come here to awaken (the Arcadia of the Mages is within human experience, the Arcadia of the Fair Folk is ''not'', and the nature of their connection is debated even by the Archmages - Arcadia is that screwy).
** Another screwy realm is the [[{{Hell}} Pandemonium]] where the Mages of Mind and Space awaken. This is where YourMindMakesItReal is the guy in the cubicle next door, who is doing reality's work while reality is out to lunch.
** ''TabletopGame/DemonTheDescent'' eventually reveals ''why'' the World of Darkness is so screwed up; there's a secondary set of "occult physics" that allows weird shit to come into existence if weirder shit is done to generate it. A lot of these experiments are set up by the God-Machine and its agents, but sometimes, the principles just fulfill themselves on their own.
* Most of the Umbra in the ''TabletopGame/OldWorldOfDarkness'' gets pretty close. Even areas under the hard control of the [[PowersThatBe Weaver]], the spirit of stasis, tend to have unusual flow of time and sentient spirits of data running around. Where the Wyld or Wyrm rule, even simple things like waking up the same shape you started as is a rarity.
* The interior of Hundun, the Titan of Chaos, in ''TabletopGame/{{Scion}}'' cannot be mapped in any reasonable manner. To do so would be to define it, and Hundun ''cannot'' be defined. This renders Hundan impossible to [[SealedEvilInACan seal away]], but thankfully, it's so chaotic that it cannot focus long enough to act. And then the other Titans got out and asked Hundun for assistance...
* The original [[TabletopGame/DungeonsAndDragons AD&D]] module "Q1: Queen of the Demonweb Pits" included a table of random RealityIsOutToLunch events that can occur while the heroes are exploring Lolth's spider-ship, due to the inherent chaos of the Abyss. It's stated that these would be much more common and severe, if Lolth's own willpower weren't keeping them in check to preserve her headquarters.
** There's also the Far Realm, the place of Creator/HPLovecraft's nightmares. Nevermind that it's THE location that nearly every EldritchAbomination spawned from, there are areas where it leaks over into the real world, causing some... interesting effects. The more ''mundane'' ones are stretches of exposed bedrock with the consistency of chocolate mousse, balls of psychic energy randomly coalescing into semi-sentient beings, the typical [[BodyHorror tentacular mutations]], and, of course, general insanity. Depending on the setting, the stars in the night sky are actually the remnant tears left over when beings of the Far Realm broke into the mortal plane; in others, the stars ''are'' said Eldritch Abominations, they ''know'' you're watching them, [[ParanoiaFuel and they're watching you back, filled with incalculable malice]].
** Limbo, the realm of pure Chaos, is rather like this. Wild Magic is the rule there, rather than the exception, and the whole place basically exists in an endless state of creation, with new things coming to existence all the time.
* The Mournland from ''TabletopGame/{{Eberron}}'' is a low-key example of this, seeing as it turned into the magical equivalent of a nuclear test site during the final years of the Last War. How bad is it nowadays? One of the common enemy types in the area is sentient ''spells''.
* In the TabletopGame/{{Ravenloft}} setting, the Forest of Everchange in the Nightmare Lands is only called that because its constant transformations are ''slightly'' more likely to result in forest than other terrain types. The domain of Vechor is also prone to this, as its darklord is a RealityWarper and batshit insane.
* The ''TabletopGame/{{TORG}}'' RPG features an invasion of Core Earth by other realities (cosms), in which those alternate realities' laws of nature are superimposed on the invaded/supplanted territories. This means you can have fantasy, super-science, ''mad'' science, horror, pulp-adventure, and cyberpunk tropes all mixing it up in the same game-setting.
* Earth in ''TabletopGame/{{Rifts}}'' has also been invaded by other strange realities.

[[folder:Video Games]]
* The Mystery Vortex in ''SamAndMaxHitTheRoad''. Almost every single room of this tourist trap appears to feature some disruption of reality, from the Creator/MCEscher entrance hall where visitors become too small or too tall to enter certain doors, to the permanently upside-down gift shop.
--> ''Sam'': "Gravity has taken a holiday and lost its luggage!".
* In the ''[[VideoGame/{{Stalker}} S.T.A.L.K.E.R.]]'' series, reality isn't out to lunch as much as [[UpToEleven it's on extended medical leave]]. The old Chernobyl power plant exudes... [[EldritchLocation weirdness]], moreso during a blowout, which, even aside from all the potentially fatal radiation, REALLY tends to mess things up. Just for example, you might be walking along a perfectly normal mutant-infested swamp only to have gravity suddenly crush you into the ground, possibly fatally. And that's a rather mild example. There are also the stretches of ordinary unremarkable ground which exude enough heat to burn a human to death ''for no reason at all'', the random massive electrical discharges, the always-entertaining white-hot jets of flame from out of nowhere (that only hurt upon ignition and can be harmlessly traversed after that until they reset), the plants that dissolve skin on contact depending on the speed something passes by it, and [[AlienGeometries the occasional place where space has folded in on itself and created a bizarre maze out of an ordinary room]]. And that's because we haven't said a word about the [[AmplifierArtifact artifacts]] these bizarre occurrences create, and which are very strange in and of themselves.
* ''VideoGame/InfiniteSpace'' has fluctuation sectors. Apparently, it can be stabilized using the [[BlackBox Epitaphs]] [[spoiler:or the power of [[ArtificialHuman Observers]] (and possibly Trackers)]].
* The eponymous location in ''VideoGame/ImprobableIsland'' was the testing ground for a device that was supposed to disprove the laws of thermodynamics by creating more energy than it used. It created ''something'', all right--things and people that spend too long there tend to turn into other things, often in surreal ways.
* Higure Anghel of ''VisualNovel/HatofulBoyfriend'' can create this kind of effect. He's able to draw people into different fantastical versions of baseline reality when he's particularly excited, and their bodies and sometimes minds change to suit. See: Primal Feather, Wallenstein, Pretty Coore. He claims to be a FallenAngel, he definitely has [[spoiler: intoxicating/hallucinogenic pheromones]] and strange RealityWarper powers whose full extent he is not aware of. If he leaves the area, stops making an effort, or loses consciousness things return to normal, though something destroyed remains destroyed.
* ''[[{{Silent Hill 1}} Silent Hill]]'': Nowhere. It's an amalgamation of all areas of the city that Harry's been through, organized in such a bizarre and nonsensical way that the only thing a room has in common with the ones it's connected to is the size of the door they share. It's not restricted to the Otherworl areas as it seems at first, either: some Fog/Dark World locations are present, such as the school classroom. To make it worse, even the savegame screen isn't immune: ''it can't identify the place you saved the game in''. All save points but the final one register the save location as "Nowhere".
* In ''VideoGame/{{Metro 2033}}'', one of the side effects of the nuclear war that destroyed most of humanity is that reality now sometimes... falters a bit in certain parts of the Metro. The first game included bizarre electrical anomalies that appear out of nowhere and float down tunnels, shocking everything around them, and some kind of sentient room that induces a hallucination of a great, glowing door that traps and kills people. ''VideoGame/MetroLastLight'' followed suit with an EldritchLocation called the "River of Fate", where dead skeletons move around like they're alive, the dead can make phone calls, and swimming in the river can allow people to visit entirely different places and times.
* Reality in ''VideoGame/FirstEncounterAssaultRecon'' goes out for a smoke break whenever Alma pays a visit. Then it goes to lunch. And visits the gym. And takes a three-day weekend. [[OverlyLongGag And quits its job]]. In the meantime, ghostly horrors and dismembering tentacles will erupt from nowhere, and monsters lurking in pools of blood will erupt without warning, and this is before Alma herself starts ''actively'' transforming the environment around you. Interestingly, the developers [[InvertedTrope invert]] the usual RealIsBrown pattern: a monochromatic or desaturated color palette indicates that some seriously ''[[SurrealHorror unreal]]'' stuff is about to go down.
* ''VideoGame/{{Psychonauts}}'' has you delving into a colorful cast of characters' mindscapes, which have their own laws of physics. That said, the "real world" features a psychic summer camp with telekinetic wildlife.
* ''VideoGame/KerbalSpaceProgram'' has a long running bug known by the community as the "Deep Space Kraken" that has been known to make planets invisible, tear apart spaceships for no apparent reason, and in general wreak havoc on your save. The original Kraken was caused by a floating point error, but since its fixing multiple different Krakens have thence spawned.
* ''VideoGamee/KingdomHeartsI'':
** The VeryDefinitelyFinalDungeon, End of the World, created from the remains of worlds consumed by TheHeartless. The phenomena there includes: small islands floating in a purple void with spheres of darkness (which contain snowy canyons filled with treasure chests) constantly dropping on them; towers of rock that contain purple flames that can transport someone to other worlds (or [[spoiler:[[Disney/{{Fantasia}} Bald Mountain]]]]); an ornate door at the bottom of a cavern that opens up to [[spoiler: [[DoomedHometown Destiny Islands]], which splits open to reveal a valley made of purple rock]]; and a lot of [[WombLevel organic-looking structures]].
** Hollow Bastion, which has also been consumed by darkness. The laws of physics don't work properly due to the world being damaged; Water acts as a solid surface and flows uphill, there are floating landmasses, and bubbles of water can levitate and transport people underwater, among other things.
* ''Videogame/FallenLondon'': The Neath in general has tons of weirdness, like honey that physically teleports you into your own dreams, people selling their souls in bottles like nothing and death being a bit of a temporary inconvenience. But the Iron Republic takes this to new levels; the laws of reality are nonexistant, very, very malleable or ''literally'' debatable, changing at the behest of its rather insane inhabitants' protests. The laws of mathematics change so often doing any sort of accounting is irritating, and figuring out theorems is blatantly impossible. Make a convincing argument and it'll rain upwards just because you asked, until someone else asks for something blatantly impossible instead, which will happen anyways. Why all this chaos? Because this is the Iron Republic's idea of true freedom: There shall be no law. This includes things like physics.
* Whenever the [[CosmicHorror Dreamers]] are encountered in ''VideoGame/TheSecretWorld'', you're sure to wind up with some craziness. Sometimes, it almost makes sense. Other times, you wind up with a delicious [[TimeyWimeyBall space-and-time pretzel]], with [[{{Metaphorgotten}} mustard and ranch dressing.]]
* At the very end of ''[[Videogame/{{Inca}} Inca II]]'', the protagonist winds up inside an asteroid comprised of his memories, as well as some sort of bomb which needs to be wrapped back in around itself. The maze alone is suitable enough to warp one's mind, but the puzzles - even for a game which has ''already'' been out there and back -- are sublime.
* In the climax of the Team Galactic plot of ''VideoGame/PokemonPlatinum'', you, Cyrus and Cynthia enter the Distortion World, the realm of [[OlympusMons Giratina]] described as being on the reverse of the normal one. It is defined by its disconnection from natural space and time - platforms appear out of nowhere, obstacles vanish (or spontaneously generate) as you walk towards them and gravity changes on a whim. At one rather impressive point, you surf up a waterfall simply by holding the D-Pad - a waterfall that flows from the bottom of the screen to the top. Cynthia remarks that although you appear to keep moving downwards toward the centre, in a world such as this its impossible to know.

* In ''Webcomic/{{Unsounded}}'' the Khert is simultaneously a BackgroundMagicField that regulates reality and a timeless, nondimensional EldritchLocation in itself. Powerful enough magic can disrupt the Khert in an area so that physical laws malfunction: fire burns cold, ghosts escape into the physical world, mugs of coffee learn to fly and socialize, and the like. [[spoiler:Inside the Khert, the memories of everyone who has ever and will ever live are manifested and remade into the scenery, it's possible to glance down one vista of the fractal landscape and watch the time you visited last night, and you can fall headfirst into a vision of the future -- [[MindScrew or a possible future?]]]]
* Reality spends A LOT of time at lunch in ''Webcomic/MountainTime'', where the sky is full of ham, settings change mid-conversation, and people suddenly discover they've recently robbed a bank.
* ''Webcomic/AwfulHospital'' doesn't have anything as normal as reality. Its local take on a {{Multiverse}} is the Perception Range, an infinite expanse of possibilities and subjective realities that people interpret differently based on what they're willing and able to perceive, subdivided into more-or-less discrete "Zones". Locations include the Grey Zones, our own laughably limited reality; a SmallSecludedWorld that grew out of one of the protagonist's corpses, populated by symbolic representations of fungi and bacteria; and The Hospital, the realized concept of medical care, which is under attack by an EldritchAbomination sabotaging the platonic ideals of sickness and health. MindScrew doesn't cover it.

[[folder:Web Original]]
* Several places in the WhateleyUniverse, including the Dreamscape where Sara Waite has to fight The Kellith to the death [[spoiler: even though they are the same person]], or Gothmog's domain, or even the dimension where the demon '''BKCRMWDJVG''' comes from.
* ''ANYTHING'' that comes out of WebAnimation/RubberFruit's head.
* In the titular desert town of ''Podcast/WelcomeToNightVale'', reality is on a permanent bad acid trip.
* In ''LetsPlay/TwitchPlaysPokemonFireRed'', the majority of the mons can use moves and abilities that don't even fit their anatomy. The mob was amazed when they encountered an Abra with the Levitate ability (i.e, something that makes sense in the WorldOfChaos that is Kanto during this run).
** ''Pokémon'' Randomizers in general. You can make a randomized rom up to or more chaotic than the settings the streamer of the aforementioned run used. If movesets, abilities, and possibly even types are randomized along with encounters, expect the mons you see to not even follow the laws of physics.

[[folder:Western Animation]]
* The ''WesternAnimation/EdEddNEddy'' episode "One Plus One Equals Ed" involves the Eds [[BizarroEpisode taking reality apart to see how it works.]] Among other things, Eddy turns day into night by taking a bite out of the sun and turning it into a crescent moon, steals Jimmy's outline (turning the lad into a puddle of goo), and forces Sarah to go away by generating a WheelOFeet and sticking her in it. Ed uses a hand saw to create an interdimensional hole into the Kanker's bathroom, and then things get ''really'' weird.
-->'''Edd:''' Don't look now, but there's a cow hovering just overhead.
* Wackyland in the ''WesternAnimation/LooneyTunes'' cartoons. Like Wonderland, but with more dodos.
** Wackyland is an actual place in ''WesternAnimation/TinyToonAdventures'', situated on the outer edges of Acme Acres. A few episodes focus on it, like one in which Babs briefly became their queen or the time Gogo Dodo took Montana Max to task for dumping sewage in it and spoiling his surreal surroundings.
* ''WesternAnimation/StarTrekTheAnimatedSeries'' had an episode called "The Magicks of Megas-tu", where the Enterprise enters a part of the universe where reality breaks down. One character has their arm break off of their body and drift away.
* The ''WesternAnimation/TeenTitans'' episode "Fractured" features the inter-dimensional imp Larry, whose "magic finger" can bend the rules of reality. So, naturally, when he breaks his finger, reality gets broken along with it. This includes making an entire city look like it was drawn in crayon, Starfire's head growing wings and flying away from her body, and mouths becoming easily detachable from people's bodies.
* In ''WesternAnimation/MyLittlePonyFriendshipIsMagic'', this happens to Ponyville in the season 2 premiere "The Return of Harmony (Part 1)", thanks to Discord's influence. The weirdness includes cotton candy clouds that rain chocolate milk, [[PopcornOnTheCob ears of corn popping while still on the stalk]], and rabbits growing long, deer-like legs. It gets progressively weirder in "The Return of Harmony (Part 2)", where Discord throws in things like dirt roads turning into wet soap, day and night cycling at random, buildings floating in midair, [[AstralCheckerboardDecor the ground developing a checkerboard pattern]], [[http://www.youtube.com/watch?v=NjD4umwKSLI drinking an exploding chocolate milk of glass,]][[note]]You read that right. As seen in the video, when Discord tips of the glass into his mouth, the glass itself flows into his mouth, leaving the chocolate milk inside untouched and still holding the shape of the glass.[[/note]] and more.
* In ''WesternAnimation/XMenEvolution'', when the ComicBook/ScarletWitch cut loose against the X-Men in her debut episode, she made the entire area (and the X-Men's powers!) go crazy. It's hard to fit the things she made happen under 'probability alteration,' but damn, if it wasn't ''awesome.''
* ''WesternAnimation/RegularShow'' has this happen occasionally, such as when Mordecai and Rigby go beyond time in the episode "It's Time" where everything is invisible as far as the viewer and Mordecai can tell, and the time-lord exists as a mass of talking clocks.
* The world went this way in the ''WesternAnimation/AdventureTime'' episode "A Glitch is a Glitch," due to The Glitch breaking down reality at the fundamental level, bits and parts of people and things disappeared haphazardly.
* Anyone venturing into the city of Lost Angles in ''WesternAnimation/ReBoot'' gets such fun experiences as: gravity working in different directions; walking through doors/behind objects and ending up in some random other location; Tears appearing and disappearing at random (well, even more randomly); and of course, the joys of navigating the already [[AlienGeometries twisted landscape which is only made worse by the above problems]]. And all of this is WITHOUT the interference of Hexadecimal, the insane RealityWarper that saw the [[spoiler:after-effects of an experiment to open a portal to the Net that destroyed and twisted an entire drive or "city" of Mainframe]] and thought it looked like a cozy place to set up shop.
* In ''WesternAnimation/TheAmazingWorldOfGumball'', Richard got a job delivering pizzas. [[TheSlacker Richard]] getting a job is so alien to the universe as we know it that in every move he makes he [[RealityWarper warps reality]] where ever he passes, such as changing the weather, making stuff float, and reshaping people. [[spoiler:Things go back to normal when he got fired (for eating one of his deliveries).]]
* In the ''WesternAnimation/GravityFalls'' episode, "Weirdmageddon", [[spoiler: Bill Cipher finally escapes to Earth and turns Gravity Falls into his own personal playground, unleashing all sorts of bizarre and horrifying transformations on the townsfolk and partying it up with some of his fellow {{Eldritch Abomination}}s from his previous home dimension.]]

[[folder:Real Life]]
* Dreaming is an example of this. With sufficient practice, dreams can even be shaped.
* Quantum physics:
** Quantum tunneling. Imagine a real-life example: you can't push something up a hill if you don't supply enough energy to it, but it gets that energy back when it rolls down on the other side. If you don't have enough energy to get it up in the first place, in real life you're out of luck. On the quantum scale, this doesn't seem to matter as much. There's a good chance that if you aren't being observed, you can pass right through the hill and be on the other side of it when reality comes back from lunch.
** Quantum physics is really an inversion. ''Reality'' works perfectly fine and even consistently at that level, it's ''we'' who have trouble fully understanding how it does so.
* It's theorized that there are parts of the universe where matter randomly comes into existence, though usually not in a coherent form (that we know of...).
** A Boltzmann Brain is a complete human brain created by this process. It's estimated that one will probably show up sometime in the next 10^10^50 years.
** In particle physics reactions, there can exist "virtual" particles which have invariant mass much different than what would be that particle's usual mass (if that particle weren't extant only as part of a reaction). Example: An electron and an antielectron (positron) annihilate, to form a single photon that has mass equal to the total center-of-mass energy of the two electrons, then that photon decays after a time to an electron and a positron with the same center-of-mass energies as the originals. A free photon would normally have zero mass and not decay, but here the virtual photon has mass, but decays - almost literally it is "Reality is Out to Lunch," and when reality "catches up" with the improperly-massed particle, it decays. Or at least that's one way to think about it. Of course, this is a "cartoon" picture, since in real life it's impossible to "see" the virtual particles, so it's hard to say whether they "exist" or not.
** For any given space, there are a finite number of ways that space can be filled. Theoretically, a sufficiently large universe should contain copies of complex structures, and eventually entire observable universes. However, since these repetitions are not fractal or in any way dependent on one another, the result would be a "glitch universe" where such things as human bodies randomly floating in space occur.
* A lot of higher mathematics invokes this trope, playing around with imaginary numbers, hypothetical spatial dimensions, and conceptual permutations of infinity.
** The fun thing about mathematics is that it doesn't have to reflect reality at all; it only usually does so because that's more convenient for most things. Want to redefine "continuity", make a [[http://en.wikipedia.org/wiki/Long_line_%28topology%29 longer-than-infinite line]], work in fractional or infinitely many dimensions, or [[https://en.wikipedia.org/wiki/Banach-Tarski_paradox split a sphere into two copies of itself]]? As long as you can formally define it and prove it works, there's no problem.
** And in a sort of inversion of this trope, sometimes branches of mathematics have been developed with no intention to model the real world, only to then be useful in modeling it after [[ScienceMarchesOn science marched on]]. For example, non-Euclidean geometries were first developed accidentally while trying to disprove the parallel postulate (which of course [[GoneHorriblyWrong went horribly wrong]] because the parallel postulate is what makes a geometry Euclidean), only to then be useful for modeling the Earth's surface and relativity.
