->''"Toto, I have a feeling we're not in Kansas anymore."''
-->-- '''Dorothy Gale''', ''Film/TheWizardOfOz''

A standard plot/MythArc for SpeculativeFiction: The OrdinaryHighSchoolStudent, frequently his friends, and sometimes his enemies are all transported (often [[SummonEverymanHero summoned]]) to another world -- distant planet, a MagicalLand, AlternateUniverse, [[TheTimeOfMyths the]] [[TrappedInThePast past]], TheFuture -- where they find they have an important role to play in Events of Significance that are occurring at the same time as (or sometimes because of) their arrival. Usually there is no hope of their [[ClosedCircle finding a means to return home]] until after the great threat facing them has been defeated. Occasionally, they will then [[IChooseToStay question if they even want to leave]], especially when there is an ongoing FantasticRomance.

In LightNovels this is known as the "Isekai"[[note]]Literally "Another World"[[/note]] genre, and usually features a character who gains [[RPGMechanicsVerse RPG-like powers]] on arrival (or at the very least, is set in a RolePlayingGameVerse). These stories often feature alternate methods of bringing the protagonist to the new world, such as {{Reincarnation}}, [[FreakyFridayFlip swapping bodies with an inhabitant of the new world]], or [[TrappedInTVLand becoming their own MMORPG avatar]], though simple bodily transport is still common. Recently, these types of stories have become popular thanks to Japanese publishing companies like Creator/{{Alphapolis}} and Media Factory.

In {{Literature}} this is often referred to as a "Portal Fantasy". This plot device is extremely popular in [[{{Crossover}} Crossover Fanfiction]].

If it's the hero's job to bring back a trapped person, it can become an OrpheanRescue; while if someone else turns up to bring back the hero, it's WeirdnessSearchAndRescue.

SuperTrope to PortalBook, PortalPicture, SummonEverymanHero, and TrappedInTVLand. Often overlaps with DownTheRabbitHole, FishOutOfWater, and YouCantGoHomeAgain. The [[InvertedTrope inverse]] of AlienAmongUs.

Compare with KidnappedByTheCall. Compare & constrast with ConstructedWorld and {{Xenofiction}}, which feature other worlds that don't involve present-day Earth at all. For generic types of other dimesions, see AnotherDimension. See also TheHomewardJourney.

!!Examples:

[[folder:Anime & Manga]]
* Long-running shoujo series ''Manga/AnatoliaStory'' and ''Manga/OukeNoMonshou'' both feature this trope, a girl from modern day trapped in Ancient Mesopotamia and Ancient Egypt respectively.
* The main premise of ''Manga/ArataKangatari''; Arata of the Himezoku is transported to modern-day Japan, while Arata Hinohara is trapped in the world of Amawakuni.
* ''Anime/AuraBattlerDunbine'', but then it twists it by having all the people from the other world get sent to ''Earth''.
** ''Anime/TheWingsOfRean'', made by the same director and in the same setting, is like-wise, although both are more like "people from Earth get sent to another world who then get sent ''back'' to Earth and then get stuck there with otherworlders."
* This also occurs in ''VideoGame/SuperRobotWarsCompact'' and ''VideoGame/SuperRobotWarsAlpha'' with the [[Anime/MobileSuitZetaGundam Argama and its crew]], who meet the Dunbine characters there.
* In ''Anime/BeautifulFighterGeheim'', Yoko falls down an open manhole and is transported to the otherworldly kingdom of Spaetzle, where she becomes a Geheim, one of an elite class of young female warriors who pilot HumongousMecha.
* ''Manga/BloodLad'': Not only is Fuyumi Yanagi a human girl trapped in {{Hell}}, she ''dies'' in it. And the story is then focused on bringing her [[BackFromTheDead back to life]].
* ''Carol: A Day In A Girl's Life'': The heroine is transported to a fantastic world where she must fight against the evil monsters who are stealing the music from Earth.
* In ''Choujin Koukousei-tachi wa Isekai demo Yoyuu de Ikinuku you desu!'', seven high school students get into an airplane accident, and wake up to find themselves in a middle age-esque fantasy world where magic and beast-men (called juujin) exist. Unlike most protagonists of this kind of plot, however, they are high school students that excel at politics, economics, science and medicine, which enables them to build a nuclear plant in a world without electricity, control the economy of a large city in a short work's trip, and declare war on the evil nobles.
* In ''Anime/CosPrayers'', Koto and the others get stuck in the parallel dimension in the first episode, and spend the rest of the series fighting the forces of evil.
* In ''Manga/DeadlineSummonner'', [[ButtMonkey Mamoru]] [[NiceGuy Onodera]], an {{Otaku}} [[GenreSavvy fond of RPGs]] finds himself sucked into a fantasy world filled with [[CuteMonsterGirl monster girls.]] For reasons unexplained in its first and only chapter, he somehow ends up the master of [[BattleHarem ten girls who could easily rip him to shreds]] [[OutWithABang with their affections]]--[[ClingyJealousGirl or get him caught in the crossfire of their inevitable fights.]]
* Occurs frequently in ''Franchise/{{Digimon}}'':
** ''Anime/DigimonAdventure'' starts with seven kids being unwillingly transported to the "Digital World", a dimension full of sapient creatures somehow created from data in the real world. The kids initially have no idea how to get back.
** ''Anime/DigimonTamers'' has the protagonist kids purposefully travel to the Digital World in an attempt to rescue someone, but they are left uncertain of how to return to the real world.
** ''Anime/DigimonFrontier'', much like Adventure, starts with a group of kids being transported (somewhat willingly, there is a ''CallToAdventure'' beforehand) to the Digital World without knowing a way to get back.
** ''Anime/DigimonXROSWars'' begins with Taiki [[CallToAdventure answering Shoutmon's plea for help from the Digital World]], but he ends up dragging the unwilling Akari and Zenjirou with him, to their great displeasure. The three remain stuck in the Digital World until an enemy attack throws them back home in the middle of the series.
* In ''Anime/DogDays'', the people of Biscotti [[SummonEverymanHero summon]] Cinque to help them, but then find that they don't know how to send him back to Earth. This no longer becomes an issue once they find the return spell.
* This happens to Tsukasa from ''Anime/DotHackSign'', with a computer game.
* ''Anime/DualParallelTroubleAdventure'' is a variation in that the other world is a AlternateUniverse, one that split based on whether a construction worker threw away LostTechnology or decided to hang onto it. The protagonist can also see glimpses of the other, parallel world for years before finally entering it.
* ''Anime/ElHazardTheMagnificentWorld'': When Ifurita sends Makoto to El-Hazard, and accidentally sends along Fujisawa-sensei, Jinnai and Nanami as well.
* ''Anime/{{Endride}}'' has the protagonist get sucked into another world via a magic crystal. It turns out the other world, Endora, is just the inside of his own hollow world and the Endorans historically know of "the surface" even though "the surface" only has myths like Shamballa.
* Saito in ''LightNovel/TheFamiliarOfZero''. He is a normal teenager from modern Japan and is trapped in Louise's world that is a medieval fantasy world with young witches, wizards, elves, ecc.. . In the novels, one of his main motivations is getting back to his own world. [[spoiler: He managed to find a possible way back to Earth, via a Void-based portal spell. By then however, he became too attached to Halkeginia and decided not to leave. At least for now.]]
* ''Anime/FinalFantasyUnlimited'' begins with two KidHero siblings being trapped in the Inner World/Wonderland. Said other world is also continually expanding and consuming other worlds, leading to entire dimensions being trapped there as well.
* ''Manga/FromFarAway'': high school girl Noriko falls into a fantastical world.
* In ''Manga/FullmetalAlchemist'', the first Homunculus is trapped in the human world ''and in a flask'', which he admits sucks, but he's not that bothered about it. [[spoiler:Later he tries to use the human world to "eat" the entity that controlled him in his world. Ironically, he ends up trapped in his own world, [[AndIMustScream presumable tortured for eternity]].]]
** In ''Anime/FullmetalAlchemistTheConquerorOfShamballa'', [[AlienAmongUs in an inversion]], they are trapped in ''our'' world, having originated from another, where [[strike:magic]] alchemy is fairly commonplace.
* ''Manga/FushigiYuugi'': Miaka and Yui get pulled into a mythical world inside a magical book. [[spoiler:The same thing happened to their predecessors, Suzuno and Takiko.]]
* ''Anime/GarzeysWing'': Chris is summoned to an ancient world (well, his ''spirit'' is -- his physical body remains on Earth) by an enslaved tribe who want him to lead a revolution.
* In ''Anime/GenmuSenkiLeda'', Yohko is transported to the MagicalLand of Ashanti, where she becomes the leader of LaResistance.
* Subversion: Yukinari from ''Manga/GirlsBravo'' gets trapped on the planet Seirun in the first episode, but is returned to Earth in the same episode.
* In the NotSafeForWork {{OVA}} ''Hooligan: Quest for the Seven Holy Dildos'', a botched science experiment transported the hero Yukito to another world, and he now has to find the Seven Holy Dildos in order to get home.
* In ''LightNovel/InAnotherWorldWithMySmartphone'', Touya is reborn in a magical world after accidentally being struck by lightning along with his Smartphone. In addition to this, he is given magic powers.
* Kagome from ''Manga/InuYasha'' in the first few episodes. Afterward she's able to go between the other world and her own at will. [[spoiler: She willingly leaves her world behind, knowing she can never return home, to live with Inuyasha in his world in the series finale.]]
* ''Anime/IxionSagaDT'' centers around a normal gamer from Earth who after accepting a request from a female character in a video game, gets sent into a fantasy world called Mira. He ends up stuck with a young princess and becomes part of her honor guard when all he wants to do is go back home.
* ''Anime/JewelpetKiraDeco'': the Kira Deco 5 travel to Jewel Land on an asteroid and stay there until their quest is concluded. Slightly different from most examples in that they're there willingly.
* ''Anime/JuraTripper'' sends no less than 15 people to a planet where humans and dinosaurs co-exist.
* ''Anime/LegendOfHimiko'': Himiko and her schoolmate Masahiko are transported to the magical kingdom of Yamatai, where they have to fight alongside a resistance force to overthrow an evil empire.
* ''Anime/MagicalShoppingArcadeAbenobashi'': After the first episode, the heroes fall from world to world, each one based on one of the main characters' [[{{Otaku}} geekish]] hobbies.
* ''Manga/MagicKnightRayearth'' does this to Hikaru, Fuu and Umi.
** ''Anime/RayearthOVA'' inverts this. Clef sends the rest of the people of Earth to another plane to keep more people from being killed.
* The ''Manga/MahouSenseiNegima'' manga has Negi and a group of his student get stuck in the Magic World after [[spoiler:Fate destroys the gateway between worlds.]]
* Ginta of ''Manga/{{MAR}}'' actually makes the willing decision to go to the other world (after wordlessly making sure his love interest is unable to follow him), and once there is overjoyed to find that getting back isn't going to be easy.
* ''Melo Melo Melonpan'' has a short story about a gamer sucked into a ''VideoGame/DragonQuest'' expy, ''then'' (being that this is an H-Manga) he realizes the [[ArtificialHuman NPCs]] ''don't'' have BarbieDollAnatomy and [[LampshadedDoubleEntendre functionally]] robotic humans that repeat the same programmed lines ad nauseum [[VideoGamePerversityPotential he proceeds to have sex with EVERY woman in the kingdom]] including, but not limited to his [[NotBloodRelated in-game "mother,"]] potential party member, [[NunTooHoly a nun,]] a mother [[RefugeInAudacity right in front of her son in the town square as she walks,]] and [[EverythingsBetterWithPrincesses the queen and princess]] while completely ignoring the mission. Unfortunately or fortunately for him, his real-life mother thinks he merely left the game on again, turning it off and stranding him there forever.
* Downplayed in ''Manga/MissKobayashisDragonMaid''. While none of the dragons are natives of Earth, most of them have the ability to freely conjure up inter-dimensional portals. The only ones who are "trapped" on Earth are Kanna and Elma. Kanna could theoretically go back at any time with Tohru's help, but she'd just be sent back to Earth anyway because she had been banished. Elma on the other hand got stuck chasing after Tohru, lacks the ability to make her own portals, and isn't on the best of terms with those who can.
* The plot of the ''Anime/MonsterRancher'' followed the adventures of Genki Sakura, a very hyperactive boy who wins a beta disk of "Monster 200X" (which has the same properties of the real MR game) in a video game tournament. No sooner does Genki start it, than he is transported inside the game, finding a real world of monsters inside.
* ''Anime/MujinWakuseiSurvive'' involves 7 {{Ordinary High School Student}}s and a [[NonHumanSideKick robot cat]] getting stuck on another planet.
* The Sorcerer's Curse arc of ''Manga/MythicQuest'' revolves around everyone in the world being deposited in the dimension created by the {{MMORPG}} Mythic Quest with no way out and no extra lives.
* ''Anime/NarutoTheMovieRoadToNinja'' features the titular character and his teammate, Sakura, being sent to an AlternateUniverse by Tobi.
* ''Anime/NowAndThenHereAndThere'': This is an exceptional example of this trope because the creators [[{{Deconstruction}} threw out every convention associated with it from episode 1]]. Shu sees a strange young girl sitting on a smokestack on his way home from school and goes to meet her. As he is introducing himself he and the girl are attacked by people teleporting in from the distant future in pursuit of that girl. True to the genre Shu picks up a stick and fights to defend the girl. He immediately gets his ass handed to him and both he and the girl are dragged forward billions of years where Earth is a dying desert planet orbiting a sun in the early stages of nova. What follows is a relentless thirteen episode trip through the ninth ring of Hell.
* ''Anime/PanzerWorldGalient'': At the climax of the story, [[spoiler:the main character and all his friends and allies were transported to another planet.]] As they were trapped in that world, [[spoiler:they had to fight the BigBad and find a way back to their homeworld because that planet was about to blow up.]]
* In ''Anime/QueensBlade Grimoire'', Alicia is a magic swordswoman from Gainos who finds herself in Mel Fair Land, which resembles Wonderland from Alice in Wonderland. Nobody knows how to return her to her home, so she decides to join the Queen's Blade tournament, hoping that winning will help her get home.
* PlayedForDrama in ''LightNovel/ReZero''. Every time Subaru dies, he goes back to a certain "checkpoint" in the story. Once he's dealt with the threat to his life, he tries to live peacefully in this new world until a new threat arises and a new checkpoint is established. Unfortunately, every time a threat is dealt with, the checkpoint is immediately established, so if Subaru can't deal with whatever is threatening him without undesired consequences, he's stuck with them.
* Happens to Hideyoshi in ''Anime/SengokuOtome''.
* The main plot of the (awful) hentai, ''Slave Warrior Maya,'' where a young woman is magically sent to another world and then tricked into undressing so she can be [[MadeASlave sold into slavery.]]
* ''Anime/SpiderRiders'' plays with this, Hunter never seems to feel like he's "trapped" in the Inner World. The reason he ended up there in the first place is because he went looking for it!
* Historical fantasy shōnen manga series SengokuStrays involves a girl from a modern era trapped in the Sengoku Era
* In ''Manga/ThereBeyondTheBeyond'', protagonist Futaba is taken to a fantasy world due to a case of MistakenIdentity. In order to get back home, he needs to reunite the Amaranthine with her master.
* ''Manga/ThoseWhoHuntElves'' do so because the elves hold the secret to the spell that will return them to Earth.
* In ''Anime/ThumbelinaAMagicalStory'', Maya gets trapped in her mother's dream world and the only way to return home is to find a way to wake up her mother. To do this, she must travel to a far away southern land to talk to the Crystal Prince, who will help her reach home.
* Same author as Manga/DeadlineSummonner, Eita Touga of ''Manga/TwelveBeast'' becomes the saviour of Live-Earth by virtue of Aero dragging him through a portal against his will. While she ''can'' send him back, the power required is so absurd that if he actually wants to get back alive, he'll have to save the world first...
* ''Anime/TheVisionOfEscaflowne'': A rare example of the other world not being treated as another dimension of some sort -- they get stuck on an invisible moon, just past the actual one.
* ''Anime/YuGiOh'' featured a couple of these in the anime-only Duel Monsters Quest and Virtual World Arcs. In both cases [[CorruptCorporateExecutive The Big Five]] trapped the protagonists in a video game as part of their plot to take over Kaiba Corp.
** ''Anime/YuGiOhCapsuleMonsters'''s main plot is Yugi and his friends being trapped in the Capsule Monster world and working to find a way home.
[[/folder]]

[[folder:Comic Books]]
* The tag line of the late Steve Gerber's [[Creator/MarvelComics Marvel comic]] ''Comicbook/HowardTheDuck'' was "Trapped in a world he never made!" A native of a TalkingAnimal world of anthropomorphic ducks, Howard fell through a portal and wound up in AnotherDimension--namely, the Franchise/MarvelUniverse version of Cleveland, Ohio.
* Creator/CrossGen's ''Negation'' featured a RagtagBunchOfMisfits trapped in an alternate universe that did not obey the laws of physics. At least one character started out convinced that it was AllJustADream.
* This is the raison d'être for the Marvel comic series ''[[ComicBook/{{Exiles}} The Exiles]]''. Superpowered beings lost from their dimension, world hop until they get to go home.
* This was ComicBook/AdamStrange's origin in Creator/DCComics. An archeologist who accidentally discovered an alien transport system, Adam became the number one hero of the planet Rann. His problem was that the Zeta beams which teleport him are only temporary and he has started a family on Rann. He has since been able to stay there permanently, but on occasion he finds himself on Earth and this trope applies there.
* ''ComicBook/ResidentAlien'' features an alien protagonist stranded on Earth with little chance of ever returning to his home planet.
* Mike Grell's DCU comic ''Comicbook/TheWarlord'', a deliberate homage to ''Literature/{{Pellucidar}}'' (in setting) and ''Literature/JohnCarterOfMars'' (in tone).
* Happens to DonaldDuck, his nephews and Uncle Scrooge in ''ComicBook/{{Dragonlords}}''.
* Sonic is trapped in the Special Zone for about fifteen issuses in ''ComicBook/SonicTheComic.''
* The premise of the ''ComicBook/{{Jinty}}'' story "Worlds Apart" -- six schoolgirls find themselves in a series of strange worlds governed by their main characteristics. There's ''one'' way out, but it's not a pleasant one...the creator of that particular world has to die.
* ''ComicBook/PowerGirl''. She was the Supergirl of Earth-2, but, after the first Crisis, Earth-2 didn't exist anymore, and Kara was trapped into the single surviving universe.
* ''{{ComicBook/Birthright}}'' desconstructs this premise with the typical teenager from Earth thrown into a fantasy land ruled by the BigBad whom he must defeat. And to do that, he is [[TrainingFromHell put through the grinder]], forced to become a ChildSoldier and [[HarmfulToMinors see things first hand]] what [[WarIsHell no one else should see]]. The end result? [[spoiler:He pulls a FaceHeelTurn, joins the BigBad because he offered to return him home in exchange of becoming his enforcer and leaves the fantasy world to rot]].
* In ''ComicBook/IHateFairyland'', Gertrude has been stuck in Fairyland for 27 years, and hasn't aged in all that time. To say she's not happy about it would be an {{Understatement}}.
[[/folder]]

[[folder:Fan Works]]
* ''Fanfic/ACrownOfStars'': Inverted with Shinji and Asuka. They had been travelling between two different universes when the portal got shut down while they were in their native homeworld, trapping them in there. Played straight with the Avaloni soldiers accompanying them that got trapped in the Evaverse.
* In the ''WebComic/SlightlyDamned'' fanfiction ''Fanfic/BlizzardStorm'' this is what kicks off the ENTIRE plot of the story. Of course, its subverted starting from Chapter 17.
* ''FanFic/DungeonKeeperAmi'' features this prominantly -- with something of a twist. The Light Gods are capable of sending Ami back at any time, and Ami is aware of this fairly early. However, due to Ami's unfortunate bonding with a Dungeon Heart, they refuse to do so. Rightly so -- if she returned to her world with a Dungeon Heart, she would inadvertently draw the Dark Gods after her. The story evolves around her attempts to discover a way around this.
* An excellent example of this trope in fanfic is ''Fanfic/WithStringsAttached''. [[Music/TheBeatles The four]] are scooped up and dropped on the planet C'hou with nothing except the clothes on their backs and some musical instruments; they're terrified out of their minds and have absolutely no idea why they're there. The reader knows they're there as the subjects of an alien undergraduate psychology experiment (at least initially, until the experiment breaks down), but the four don't learn anything for around a month, when they're told that they've been brought over and equipped to fetch the three pieces of a statue to end a continent-sized curse. The quest is legitimate in context, but was assigned to them after they were equipped.
* Fans of ''Literature/TheLordOfTheRings'' often write about girls falling into Middle-earth. These girls, and some boys, come from our modern world. With the [[Film/TheLordOfTheRings film adaptation]], there appeared a veritable storm of such stories.\\\
These fanfics tend to be mediocre to terrible. Nearly every single one of these girls is a MarySue in the guise of an OrdinaryHighSchoolStudent, who is more often that not a [[SelfInsertFic self-insert]] that falls in love with Legolas or, less commonly, Aragorn, as WishFulfillment for her author. A common trick is to transform the girl into an elf or a hobbit, to match her love interest. The inserted girl is usually a fan of the movies, and has foreknowledge of events; she might also recognize characters on sight, implying that they look exactly like their actors in the movies.\\\
Most authors use the same three conveniences: First, the inserted girl lands conveniently near major characters. She often lands near the Council of Elrond, because that is the first scene with Boromir or Legolas. Second, she can chat in English, because the author forgot that the CommonTongue is a different language. Third, she never tries to return home, because she likes living in Middle-earth.
** This is parodied in a pretty funny one [[https://www.fanfiction.net/s/9050678/1/Reasons-why-NOT-to-join-the-Fellowship-of-the-ring here]].
** ''FanFic/TimeWillTell'' is this done by a fan of the books. Jorryn from America appears in the Shire, and ends up living with Bilbo and Frodo. When Frodo must leave the Shire, Jorryn goes with him. ''Time Will Tell'' brings Jorryn through the Old Forest and to Tom Bombadil, in events from the books but AdaptedOut of the movies.
** ''FanFic/HomeWithTheFairies'' is a {{deconstruction}}. Maddie lands in Middle-earth, but she is lost. When she finds a town, she hits a LanguageBarrier [[RealityEnsues because no one speaks English or knows anything about America, her home.]] She almost dies, and lampshades the PlotArmor that seems to keep her alive. Unlike most of these characters, Maddie also wants to find a way home.
* The plot of ''VideoGame/HetaQuest''.
* In ''VideoGame/TalesOfHetalia'', the Allies and the Axis are sucked into the world of Rukassia by a magic book.
* The ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fans have a whole slew of these, referred to as "Human In Equestria" fics.
** FanFic/MyLittleWesker, in which the spectacularly evil BigBad of the ResidentEvil games becomes trapped in Equestria. [[HilarityEnsues He does not approve]].
** ''Shackles and Friendship'' has the protagonist, Rodney, become a minor EldritchAbomination due to his wierd reaction to magic-he can store limitless ammounts of it.
** ''FanFic/TheNonBronyVerse'' has our protagonist summoned to Equestria when Celestia sees him get hit by a car. Like Wesker, he also disaproves.
** ''FanFic/TheRiseOfDarthVulcan'' has the protagonist make THE Alicorn Amulet part of his EvilOverlord halloween costume, and gets teleported there when he vows its destruction.
** The Displaced Verse, wherein a mysterious Merchant sells cosplayers a trinket that gets them sucked into Equestria at the earliest opportunity, as whoever they were cosplaying as at the time. They inevitablelly upset the natives somehow and become a VillainProtagonist.
* FanFic/SlippingBetweenWorlds, in which through the agency of the mysterious Mrs Tachyon and her old-bag-lady shopping trolley - which is not what it seems - a group of British soldiers evade death on Roundworld only to end up in Ankh-Morpork on the Literature/{{Discworld}}.
* In FanFic/TheyreNotPussywillowPixies, this is what happens to Azrael, Gargamel, and the Smurfs when they go through a portal and end up in Neverland.
* Let us just say that FanFic writers LOVE this trope when they do crossovers, self-inserts, etc. It's a very common trope for Fan Fiction. So much so that it has its own FanNickname: "Bamfing".
* This trope is common in contemporary Russian fanfiction, having coined the neologism "попаданец" (literally "one who unwittingly arrived").
* The story ''Fanfic/BringMeBackHome'' involves Marinette falling through a portal into an alternate Paris, based on the ''WesternAnimation/MiraculousLadybug'' pilot video, forcing her to deal with a much less friendly Cat Noir than she's used to. In turn, Marinette's counterpart [[FanNickname Bridgette]] ends up in the familiar Paris, is forced to impersonate Marinette for the time being and quickly digs herself into a hole with Alya and Adrien by not realising that Chat Noir is much more popular than she's used to.
* Another ''Miraculous Ladybug'' fic, ''Fanfic/{{Ultrasonic}}'', involves Marinette somehow ending up in Disney/{{Zootopia}}, in the body of a white cat.

[[folder:Films -- Animation]]
* Disney's ''Disney/AliceInWonderland''. [[spoiler: Ultimately subverted when it turns out to be AllJustADream.]]
* ''Anime/SpiritedAway''.
* Manolo's predicament in ''WesternAnimation/TheBookOfLife'' once he gets to the Land of the Remembered. Because he's dead, he is unable to return to among the living to find Maria, unless he gets help from La Muerte.
[[/folder]]

[[folder:Films -- Live-Action]]
* ''Film/AdventuresInDinosaurCity'', a group of three kids are transported to the titular city.
* ''Film/{{Tron}}'': In an attempt to recover evidence that proves CorruptCorporateExecutive / [[TheCracker Cracker]] Ed Dillinger stole his promotion-worthy ideas for video games, PlayfulHacker Kevin Flynn ends up physically [[TeleportersAndTransporters digitized]] into {{Cyberspace}} by the DeusEstMachina Master Control Program.
** This has become the franchise staple, as no protagonist gets digitized voluntarily. In ''[[VideoGame/TronTwoPointOh Tron 2.0]]'' Jet Bradley gets digitized by Ma3a in a desperate act of self-preservation. Later, [[spoiler: The F-Con thugs forcibly shoot Alan in there, too]]. In ''Film/TronLegacy'' Sam learns the hard way that you shouldn't press "yes" at every pop-up dialog on a somebody else's system.
*** Oh, it's so much more bone-headed than that: Sam looks at the last command given to the computer before him (i.e. Flynn's last command) and then [[WhatAnIdiot tells the computer to run it again]]. Then again, he apparently ''did'' [[SarcasmMode inherit his old man's copious forethought]]...
* ''Film/{{Labyrinth}}''
* ''Film/{{Enchanted}}'': Characters from an animated film appear in live-action New York City.
* ''Film/{{Flash Gordon|1980}}''
* ''Film/TheWizardOfOz'': Dorothy from Kansas gets trapped in Oz. See Literature section.
* ''Film/TheChroniclesOfNarnia'': See Literature section.
* ''Film/TheNeverendingStory.''
* Creator/TimBurton's ''Film/AliceInWonderland2010.''
* Creator/DavidLynch's ''Film/InlandEmpire.''
* In ''Film/CoolWorld'', both Frank and Jack are transported to the titular world.
* In the sci-fi thriller ''Film/{{Coherence}}'', once characters pass the dark area they are randomly transported into AlternateTimelines with little hope of returning to their homeworld.
* In ''Film/JumanjiWelcomeToTheJungle'', the characters are sucked into the Jumanji world once they start the game. Averted with [[Film/{{Jumanji}} the original movie]], however - that only happened if the player landed on a certain square.
* At the end of ''Film/AvengersGrimm'', the heroes are trapped on Earth.
[[/folder]]

[[folder:Light Novels]]
* Lampshaded, discussed, and ultimately defied in ''LightNovel/NoGameNoLife''. A brother & sister {{NEET}} pair get pulled by into a world ruled by its "one true god" Tet, who has made [[TheCommandments 10 Pledges]] that force everyone to use games to decide [[SeriousBusiness almost everything]]. However, Sora and Shiro were both quite disillusioned with society back home and have absolutely '''no''' desire to go back; they even thank Tet for bringing them there.
* ''LightNovel/ProblemChildrenAreComingFromAnotherWorldArentThey'' has three [[ExactlyWhatItSaysOnTheTin problem children]] invited by a [[LittleBitBeastly Black Rabbit]] to the world known as Little Garden where competitive games decide one's living conditions.
* In ''LightNovel/TheFamiliarOfZero'', the male protagonist is "accidentally" [[SummonEverymanHero summoned]] to another world by the female protagonist in a summoning ceremony. It is later revealed that many people have accidentally ventured into this world, including a soldier from the Vietnam War and Siesta's great-grandfather.
* ''LightNovel/KyoKaraMaoh'': Though Yuuri isn't really ''trapped'', and can go back and forth between the two worlds with relative ease, he only considers himself trapped when he returns to his native world.
* ''LightNovel/TheTwelveKingdoms'': Youko Nakajima and her friends Ikuya Asano and Yuuka Sugimoto get dropped in the middle of a mostly hostile fantasy world by a 'MysteriousProtector. Though, this is apparently common enough for the locals to coin terms ("Kaikyaku" for Japanese people, "sankyaku" for Chinese) and for the government to have a regular policy in dealing with them. For example, The Kingdom of En has a standard naturalization/citizenship process while Kou just tries to round them up and kill them.
** And before they came in, a farm girl named Suzu was spirited away from the Meiji era and thrown in the same world. [[BreakTheCutie Only to go through much heartbreak.]]
** Shoryu, the king of En, also was from Japan. In fact, he was a ''daimyo'' or feudal lord whose clan was wiped away in the feudal wars. Having become a [[FallenPrincess Fallen Prince]], he accepted to become the King of En.
* ''LightNovel/WorldCustomizeCreator'' is about a young Japanese gamer finding himself in a parallel fantasy world where most people have elemental magic. The main character has the power to freely customize anything around him, which he uses to create rare magical items, heal people, and build things. To the people in the fantasy world, nothing like this has ever been seen before.
* ''LightNovel/{{Overlord|2012}}'' revolves around a high-level MMORPG dungeon created by an evil-themed roleplaying guild, which is [[NormalFishInATinyPond transported to an unrelated low-fantasy world]]. In the process its AlwaysChaoticEvil NPC guardians become sentient, and the sole remaining member of said guild becomes trapped in his [[OurLichesAreDifferent Elder Lich]] avatar as their master. As he is very fond of said [=NPCs=] (what with them being the only reminder of his old guildmates) but terrified of them turning against him, he is forced to play the role of a stereotypical EvilOverlord. Due to his undead body [[TheMindIsAPlaythingOfTheBody dulling his emotions]], and his minions' attempts to "help" him, he slowly ends up BecomingTheMask.
* In ''LightNovel/GrimgarOfFantasyAndAsh'', 12 young adults wake up in a medieval fantasy world with [[LaserGuidedAmnesia no memory of how they got there]]. They know that they come from another world (and they are initially dressed in modern day clothing), but [[LaserGuidedAmnesia are unable to remember anything past that]]. Without a way back home, they must find a way to adjust to this new world.
* In ''LightNovel/DeathMarchToTheParallelWorldRhapsody'', The main character falls asleep and wakes up to find himself in a valley. He decides to take a break from his job and tour this new world, which initially seems to be based on the game he programmed.
* ''LightNovel/LogHorizon'': At the exact moment the newest expansion for the {{MMORPG}} "Elder Tale" goes live, its entire playerbase blacks out and wakes up in the bodies of their Adventurer avatars, believing that they have been transported inside the game. At the same time, in the MedievalEuropeanFantasy land of Theldesia, the monster-hunting "Adventurer" constructs that have served humanity for generations suddenly begin acting strangely, displaying individual personalities and calling humans "[=NPCs=]". Now Theldesia must deal with the impact of an entire nation springing up overnight - one where the inhabitants have completely alien values, [[PersonOfMassDestruction the fighting strength of demigods]], and no form of government or law enforcement. The protagonists [[GuileHero must use all their political savvy]] to stabilize things and [[WithGreatPowerComesGreatResponsibility make sure that Theldesia doesn't descend into war because of their presence]].
* ''LightNovel/SwordArtOnline'':
** In the first arc, the initial 9,000-something players of the {{MMORPG}} ''Sword Art Online'' discover that they cannot log out, and that their VR headsets have been rigged with a microwave generator that will kill them if they die in-game or attempt to take it off. The only way to set everyone free is to [[WinToExit defeat the]] FinalBoss on the last of the game's 100 levels. Over the next two years, some players throw themselves at the task, some give up and prepare to spend the rest of their lives in the game, and some go mad with power and decide to take PlayerKilling to the next level.
** The ''Alicization'' arc features a virtual world inhabited by near-perfect [=AIs=], unaware of their artificial nature. It resembles a StandardFantasySetting due to being built on a modified version of [=SAO=]'s game engine, with the designers using magic as a convenient HandWave for system commands and any oddities in the simulation that they were unable to replicate. When Kirito suffers brain damage his friends connect him to the simulation in an attempt to heal him, but without offering him any clues as to how he got there.
* In "The New Gate", deals double cases of this. Firstly trapped-in-Deadly-VR-games a la ''LightNovel/SwordArtOnline'' above then protagonist is transported to dimension similar to video game but 500 hundred years later a la Overlord and Log Horizon when [[OneManArmy he, alone, killed last boss and completed the game]]. The story tells his reunions with old friends, meeting new friends, saving the day on frequent basis and finding the way home. [[spoiler: Later, it is revealed that there are 6 other players whom are trapped twice like Shin for reason yet unexplained even if the systems recognize that they are already logged out.]]
* ''LightNovel/KonoSubarashiiSekaiNiShukufukuO'' is a DeconstructiveParody of this trope in many ways. Everything from how the character gets to the other world to the people he meets to the challenges he faces poke fun at the stereotypes that are common in this subgenre as well as generic RPG cliches.
* In ''LightNovel/MagicalGirlRaisingProject Restart'', 16 Magical Girls are trapped in a game world and are forced to go through the world and defeat the demon lord in order to permanently escape. In this case, they are only trapped in it for three days at a time [[YearInsideHourOutside from their perspective]], then are allowed three days in the real world for a maintenance period, and then it repeats until the game is cleared.
* ''LightNovel/DoYouLikeYourMom'' offers a different spoof on the concept by having the main character's [[AmazinglyEmbarrassingParents clingy and overly affectionate mother]] go with him into a virtual MMORPG...and like the title says, she turns out to be a major badass while still being just as clingy and affectionate as she is in the real world.
* In ''LightNovel/AestheticaOfARogueHero'', this is actually only an uncommon occurrence in the world's backstory, with special schools being set up for those who make it back to further learn how to control and use the powers they inevitably gain there. The story actually picks up for the protagonist on his way back home.

[[folder:Literature]]
* Creator/LFrankBaum's ''Literature/TheWonderfulWizardOfOz''. Most of the first six-odd [[Literature/LandOfOz "Oz" books]] fell under this trope, with Dorothy finding her way back to Oz only to get back to Kansas by the last page, though eventually Baum just had Dorothy (along with Uncle Henry, Aunt Em, and Toto) move to Oz full-time and continue her adventures there. Whenever another human came to Oz from the outside world after that point, they generally ended up staying (Oz after the {{wicked witch}}es died and Ozma took the throne being a much more utopian place to live, occasional monsters and baddies notwithstanding). It's implied even pre-Ozma that Oz was a much better place to live than Kansas; and Dorothy only kept going back home because she didn't want to ditch her family. That certainly is her only reason after meeting Ozma, whom she has a very close relationship with.
* ''Literature/TalesOfTheMagicLand'' start of much the same as Baum (especially since the first book was a loose but recognizable translation of Baum); but Ellie and whatever relatives she takes along with her to the Emerald City always return home, and by the last book Ellie is studying in America and her cousin Fred is working on a factory, both having no intention to move to the Magic Land. It's stated that Scarecrow wanted to invite Ellie to the Emerald City as a teacher, but it's left unknown whether he did and whether she agreed.
* The ''Literature/JohnCarterOfMars'' series and the ''Literature/{{Pellucidar}}'' series, by Creator/EdgarRiceBurroughs.
* OlderThanRadio: Lewis Carroll's ''Literature/AliceInWonderland'': One of the earliest and most famous versions of this trope and a template for many later stories.
* Stephen R. Donaldson is fond of this one. It's the premise of:
** The Literature/ChroniclesOfThomasCovenant.
** ''[[Literature/TheMirrorOfHerDreams Mordant's Need]]'': a woman from the 'real world' is trapped in a {{fantasy}} realm where ''any'' reflective surface can access another universe.
* ''Literature/{{Neverwhere}}'' by Creator/NeilGaiman.
* In Creator/DianaWynneJones's ''Literature/CharmedLife'' this is what happens to Janet and her eight analogues in the other worlds in Series Twelve - when Gwendolen escapes from World 12A, she pulls Janet in from World 12B, and so on all around the circuit. [[spoiler:Janet is the only one who doesn't find the change to be an improvement, and when she realizes this, decides to stay in 12A for the sake of the others.]] Janet's parents [[AdultsAreUseless don't notice the change]].
* Creator/GuyGavrielKay's ''Literature/TheFionavarTapestry''. The five main characters are transported to Fionavar at the beginning of the first book, ''The Summer Tree'' and return to their own world at the end of it; then they go back near the beginning of the second book, ''The Wandering Fire'', and stay there through to the end of the third, ''The Longest Road'', when their various fates are resolved. At the end of the trilogy the score stands with [[spoiler: two going back to our world, one choosing to stay in Fionavar, one dead in a HeroicSacrifice, and one sailing off to eternity with Lancelot and KingArthur as she is, in fact, Guinevere.]] The books are somewhat eclectic.
* In Creator/StephenKing's ''Franchise/TheDarkTower'', Roland draws his ka-tet from [[BigApplesauce New York City]] at various points in time to his own world.
* Creator/CSLewis's ''Literature/TheLionTheWitchAndTheWardrobe''; a slight twist here is that the characters age significantly during their stay in Narnia, then are returned to their original ages when they leave. The other [[Literature/TheChroniclesOfNarnia Narnia books]] tend to follow this pattern as well, except for ''The Horse and His Boy''.
* ''Literature/UnLunDun'' by Creator/ChinaMieville - Zanna and Deeba are drawn into the titular world, a nonsensical mirror version of London, inhabited by various creatures and animated items that have been discarded by London's inhabitants.
* In Creator/AlanDeanFoster's ''Literature/{{Spellsinger}}'' series, the main character is summoned by a powerful wizard looking for another powerful wizard. Apparently, an engineer would be the closest thing to the alternate world's wizards. Unfortunately, the summoning spell latched on to the main character's job title...'''sanitation''' engineer. Fortunately, he does turn out to have magical abilities in that world.
* Creator/LEModesittJr:
** In the ''Spellsong Cycle'', the main character is summoned because of her skills as a singer.
** In the ''Literature/SagaOfRecluce'' series this trope combined with LostColony is used in two books.
* ''Literature/TheMerchantPrincesSeries'', by Creator/CharlesStross features "worldwalkers" who regularly do this to others.
* Actually inverted with ''Literature/ThePrincess99'', where an alien biker chick from the future finds herself stuck in the human world in the 1920s.
* Creator/BarbaraHambly's ''Literature/{{Darwath}}'' series: Ingold ''could'' bring Gil and Rudy back to Earth any time, at the risk of the [[EldritchAbomination Dark]] learning how it's done and coming to eat Los Angeles. [[spoiler:By the time the threat of the Dark goes away, so does our heroes' desire to go 'home'.]]
* Joel Rosenberg's ''Literature/GuardiansOfTheFlame'' series depicts a small group of college students who get magically transported to the world of their fantasy roleplaying campaign. They struggle to escape [[spoiler: but decide by the end of the first book to stay in their new home to wipe out slavery.]]
* The ''Summoning'' series by fantasy/romance author Robin D. Owens focuses on a group of Colorado women who are called, one by one, to be champions of the world of Amee. Unique in that any Earth-native brought to Amee will eventually face the Snap ... a point where Earth tries to call the person back, and will unless she has made a stronger commitment to Amee.
* The premise of ''Literature/TheInvertedWorld'' is that a city has somehow become transported to a bizarre alternate world, one where they must constantly move forwards in order to survive.
* ''Land of Oblivion'' has its KidHero protagonists transported to a place where dead children have their afterlife. The place is not all rosy, though, and they have to [[spoiler: save the girl's brother from becoming DeaderThanDead]].
* ''Literature/{{Coraline}}'' is somewhat a {{Deconstruction}} of this concept, as [[spoiler: the other world [[ExactlyWhatItSaysOnTheTin literally is a Trap for her]] (and others) -- and nothing more. Unlike most examples, the heroine is '''very''' glad to leave it behind.]]
* [[Creator/DaveDuncan Dave Duncan's]] ''The Great Game'' explains why characters in this situation tend to become heroes--anyone who's in a different dimension than the one they were born in can absorb {{Mana}}. At low levels, this just makes them [[CharmPerson really, really charismatic]]. If they [[spoiler:convince other people to make sacrifices to them (usually of blood), they can become {{Physical God}}s. All "godly" beings are actually humans from other worlds, many "gods" of Vales are actually from our world.]] [[PoweredByAForsakenChild There]] [[AGodAmI are]] [[DrunkOnTheDarkSide hazards]] [[TheDarkSideWillMakeYouForget to this]], however...
* In ''Literature/WarriorCats'', [[spoiler: Jayfeather is stuck in the past until he can turn the Ancients into the Tribe of Rushing Water by teaching them tribe customs.]]
* In ''Daughter of the Falcon'', Jessie, a girl from our world is trapped in Mysteria, a MagicalLand. This is then {{Deconstructed}} as [[spoiler: she needs insulin injections and there is nothing comparable in Mysteria, so unless she can return home, she will die when her supply runs out.]]
* ''Literature/TheRifter'': John, Laurie, and Bill have (without intending to) passed through the Great Gates from Earth to Basawar, a strange, brutal land; the gates are shut (maybe destroyed). Getting home will not be easy at all.
* In Creator/SergeyLukyanenko's ''Literature/TheBoyAndTheDarkness'', the protagonist is a teenager named Danny who travels to another world covered in [[TheNightThatNeverEnds perpetual darkness]]. His way home is almost immediately destroyed. [[spoiler:The other two portals get destroyed later]]. At the end, Danny gets the chance to go home by wishing for one thing from a [[AGodAmI godlike]] being. [[spoiler:He uses the wish to save a friend rather than return home]].
* Creator/HBeamPiper's Lord Kalvan of Otherwhen was once a Pennsylvania state policeman named Calvin Morrison, who was accidentally dropped off in a parallel universe where the Aryans went east instead of west, and conquered North America. As it happens, he lands in a small kingdom that's about to be wiped out by the CorruptChurch that holds a monopoly on the secret of gunpowder manufacture...and he knows how to make gunpowder.
* ''Literature/GrandCentralArena'': The experimental starship Holy Grail and its crew find themselves stuck in The Arena, a vast extrauniversal construct, and can't get back home unless they learn how the rules of The Arena work. Unlike most of the other examples, this one is SF, not fantasy, although there is Sufficiently Advanced tech involved.
* In Teresa Frohock's ''Literature/MiserereAnAutumnTale'', going through the Veil to the Woerld means you can never return to Earth.
* ''Literature/{{Enchantment}}'' by Creator/OrsonScottCard.
* ''Literature/AWizardInRhyme''.
* In ''Literature/DirgeForPresterJohn'', getting into or out of Pentexore is impossible most of the year, effectively trapping anyone who isn't keeping a strict eye on the Rimal.
* The titular ''Literature/{{Id}}'' finds himself trapped in a world he has absolutely no knowledge about and has no idea how he got there - but where he comes from is another mystery.
* Once you have entered ''Literature/{{Palimpsest}}'' once, you will go there whenever you have sex, whether you want to or not.
* The Holiday House in ''Literature/TheThiefOfAlways''.
* In ''GreystoneValley'', the 12-year-old girl Sarah finds herself transported into the titular valley.
* ''Literature/TheDivide'': Within the first five pages, Felix passes out above the eponymous Divide and finds himself stuck in a world where humans and science are mythical but magic and elves are real. Unusually, for most of it getting home is only his secondary objective; his primary is finding some kind of treatment for his terminal heart condition. Crossing the boundary gets a lot easier as the series goes on. [[spoiler:At the end of the series, the Divide is closed and leaves copies of Felix and his elfin friend Betony on each side, meaning that you've got one Felix trapped in the fantasy world and one Betony trapped in the human one.]]
* The main premise of the Across The Universe series. The main character is travelling in a spaceship to land on a new planet while cryogenically frozen, and she is woken up fifty years before the ship is set to land. She is trapped on a tiny ship filled with people who don't understand her and are extremely confused at how she looks (since everyone on the ship is monoethnic, and she's not).
* This trope is very common in contemporary Russian fiction, having coined the neologism "попаданец" (literally "one who unwittingly arrived").
* ''Literature/SchooledInMagic'': Emily is a modern girl in every way. For example, she is used to having access to the internet and YouTube, while the world she finds herself in is very medieval in its mindset and technology. She starts to introduce modern technology shortly after arriving, partly to rectify that.
* Literally the entire premise of the trilogy ''Literature/TheSecretCountry'' by Creator/PamelaDean, except with a slight twist as the main characters seemed to have created the world themselves and then somehow fallen into it.
* Played with in ''Literature/TheBalancedSword'', in which a group of teenagers are brought from Earth to the magical world of Zarathan by a mysterious wizard and tasked with restoring the long-lost connection between the two worlds -- but they're not the protagonists, or even in the story much; they just cross paths occasionally with the actual protagonists, Kyri and Tobimar, who are natives of Zarathan busy with a quest of their own. [[spoiler:They do play a role in the resolution of the trilogy, though: during Kyri's climactic battle with the BigBad, there's a mystical aftershock portending that somewhere offstage the connection between the two worlds has been restored, and the distraction this causes the BigBad helps Kyri to win the day.]] The author has said that he does intend to do a straight telling of the teenagers' story someday, but if he only got to tell one story about Zarathan he wanted it to be Kyri's.
* In ''Literature/{{Everworld}},'' the main characters [[HeroicWannabe David]], [[PoliticallyIncorrectHero Christopher]], [[TheSmartGuy Jalil]] and [[TheChick April]] get sucked into the titular world when [[GodOfEvil Loki]] breaches the space between worlds to abduct [[TokenEvilTeammate Senna]]. ([[MagnificentBitch Senna specifically planned this]].) Everworld is populated with various mythological gods who came there from our world ("the Old World") centuries ago, along with their mortal followers. There are also weird alien creatures who came from completely different worlds, along with ''their'' gods, one of whom is an EldritchAbomination seeking to eat all the others. Senna could bring them home, but unlike most {{MacGuffin Super Person}}s, she has her own agenda, [[AGodAmI and it's not pretty]].
* In ''Literature/CriticalFailures'', four friends invite a random guy online to be their [[GameMaster Cave Master]] for a ''TabletopGame/DungeonsAndDragons'' {{Expy}} called ''Caverns & Creatures''. The guy, Mordred, gets annoyed with them [[StopHavingFunGuys not taking the game seriously]] and insulting him, so he uses a set of magical dice to send them into the game as their characters. Then he does the same to a sister of one of the boys, who comes back unexpectedly, and her boyfriend. The trapped friends are forced to survive in a world that is suddenly real and deal with the consequences of their thoughtless actions from back when they thought it was just a game, such as lopping off the head of a guard for no good reason. They also have to abide by the rules of the game, and their skills are limited by whatever character stats they rolled before they started playing. For example, Cooper ends up being a half-orc with extremely low intelligence and charisma stats, so he constantly does something disgusting without meaning to and can't read, even though Cooper is normally literate. This doesn't apply to reading their character sheets, since those items aren't treated as of the game world. Also, Mordred keeps an eye on them through any person, creature, or object. He also reveals to them that they're not the first people he has sent into the game world.
* The main characters in ''Literature/EdenGreen'' and sequel ''Literature/NewNight'' spend at least part of their adventures stuck in an alternate dimension later named Fortuna, from which alien needle monsters have been invading Earth. The portals that allow travel between the dimensions are fickle, impossible to control until late into the second book, and even then, behave in unpredictable ways.
* In ''Literature/TheWaySeries'', [[spoiler: Patricia]] gets trapped on a parallel world, and remains there until [[spoiler: she]] dies of old age.
* ''Literature/TheWanderingInn'':Erin Solstice, Ryoka Griffin, and dozens of others, finding themselves, suddenly, in a complete different world. Some appear in monster infested places, or other dangerous places, resulting in the deaths of many.
* In ''Literature/BladeArc'', Yuuto is summoned to the MagicalLand of High World to save the world from Eternal Nidhogg, a world-eating ancient worm.

[[folder:Live-Action TV]]
* ''Series/{{Life on Mars|2006}}'':
** Though we are LeftHanging as to the true nature of the ''world''; is it TimeTravel, an alternate reality, or AllJustADream?
** And the sequel ''Series/AshesToAshes'', which resolves the mystery: [[note]]Nothing is [[RiddleForTheAges overtly stated]] about what's going on, but the central mystery is resolved[[/note]] [[spoiler: the world is a purgatory for select dead police officers.]]
** The [[Series/LifeOnMars2008 American version]] is much less ambiguous. [[note]]On the bright side, because it concluded itself after only one season, it provided the writers of British ''Ashes to Ashes'' a lesson on what NOT to do.[[/note]]
* ''Series/DoctorWho'': Rose is trapped in a parallel world, [[spoiler:but returns with knowledge of "the Darkness" threatening to destroy the multiverse (as her universe is ahead of ours). She is then forced to remain in her parallel world to take care of the clone-Doctor, despite wanting to stay with the real one. Former boyfriend Mickey, however, decides to leave the parallel world for his old one.]]
* Series/{{Sliders}}: The Sliders have a device that can take them between worlds, but it malfunctions, and they're stuck going between worlds without any control in the hope of eventually finding home.
* A staple premise of series by Sid and Marty Krofft such as ''Series/TheLostSaucer'', ''Series/{{Lidsville}}'', ''DrShrinker'', ''Series/LandOfTheLost'' and ''Series/HRPufnstuf''.
* ''Series/{{Farscape}}'', where Crichton travels through a wormhole to another part of the universe. His overriding goal for most of the series is to get back to Earth...but when he finally does, he leaves very shortly to go back to the other side of the universe. He later returns and makes it impossible for himself to ever go back in order to protect Earth from the bad guys. John, being John, makes many a reference to ''Film/TheWizardOfOz'' in relation to his situation. Title of the episode when they really go to Earth: Kansas.
* ''Series/TheTimeTunnel'' - two guys trapped in the past (or occasionally the future).
* Likewise ''Series/QuantumLeap''
* The Sterling family in the short-lived series ''Series/{{Otherworld}}''.
* ''Series/FatGuyStuckInInternet'' is about...[[ExactlyWhatItSaysOnTheTin a fat computer programer trapped in a surreal cyberspace world]].
* Season 1 of ''Series/StargateAtlantis'' -- trapped in the Pegasus Galaxy. This is a variation, because the expedition went to Atlantis knowing full well that they might be stranded there.
* ''WesternAnimation/StargateInfinity'' -- generally trapped away from Earth and the rest of polite galactic society since their iris codes had been revoked.
* According to early reports, ''Series/StargateUniverse'' is taking this tack as well, stranding the heroes on a space ship headed away from known space
** They are billions of lightyears away from home and if they could control the ship, the journey would take millions of years. They don't have enough power to dial home and dialing IN from the Milky Way needs a special kind of planet but even then, a small mistake in the calculations WILL cut off the supply line permanently via an EarthShatteringKaboom. This happened in the first episode. Later on, it was revealed that the Lucian Alliance found another planet which the SGC attempted to capture; the Alliance however activated the gate prematurely and this planet blew up as well.
* ''Series/StarTrekVoyager'' -- Trapped in the Delta Quadrant.
* The island of ''Series/{{Lost}}'' is sufficiently weird that a case could be made.
* This happens a ''lot'' in the Polish/Australian children's series ''{{Series/Spellbinder}}''. Paul gets trapped in the Spellbinder universe, Kathy's family gets trapped in the Land of the Dragon Lord, and Mek and Kathy end up trapped in first the Land of the Immortals and then the Land of the Moloch.
* In ''Series/KyleXY'', [[DeadpanSnarker Josh]] frequently suggests that Kyle is an alien from another world (although this is later subverted when Kyle's true origins are revealled).
* In season 3 of ''{{Series/Fringe}}'', Olivia is trapped a good deal of the time in another universe, an alternate universe. Peter has been trapped in another universe since he was seven years old.
* ''Series/{{Angel}}'', where Cordelia ends up trapped in Pylea and quickly goes from a slave to becoming queen. Naturally Angel and the gang soon follow to rescue her. At the end of the adventure, they end up overthrowing the ruling demon priests and freeing the human slaves. Fred was stuck there too for five years before the others arrived, though she didn't do nearly as much as Cordy.
* In the first episode of ''Series/MythQuest'', Matt Bellows gets trapped inside a mythical world with a trickster god. His children accidentally (and later deliberately) get trapped in myths when they go to look for him.
* ''Series/OnceUponATime'' is an Inversion - the fairy tale folks were dumped in our world by a curse
** OUaT ''loves'' this trope. Different people keep getting stranded in different worlds and have to find a way out.
* The premise of the series ''PirateIsland'' is that three children are trapped in a video game.
* As expected, this is the central premise of ''Series/EmeraldCity''. However, it's also revealed that [[spoiler:Jane, the lead engineer on the experiment that threw her, Dorothy's mother, and the Wizard into Oz, is also trapped there. In fact, Dorothy was born in Oz, but her mother managed to get back to our world with her and left her with foster parents]].
* This is the story arc of Season 1 of ''Series/StrangerThings''. Will gets trapped in the Upside Down dimension by the Demogorgon but is nevertheless able to communicate with his family and friends [[ItMakesSenseInContext via Christmas lights]] and Eleven's psychic powers.

Once they defeat [[BigBad Zoma]], the hole between Alefgard and the Hero's world closes, sealing them in Alefgard forever where they become known as the hero "Erdrick"/"Loto".]]
* ''VideoGame/FinalFantasyTacticsAdvance'' and ''VideoGame/FinalFantasyTacticsA2'' both use this as the main plot for the player character, but handle it in different ways. Advance has the main character wanting to go back to the real world because running away from life's problems is not healthy. A2 has the main character wanting to go home so he doesn't worry his aunt, but is in no rush to go home and tries to enjoy the time spent in the fantasy world.

* ''VideoGame/{{Nox}}'', with the protagonist's character class affecting (among other things) whether or not he returns from the titular fantasy world back to present-day Earth, or stays there.
* ''VideoGame/ZanZarahTheHiddenPortal'' is a subversion: its protagonist Amy is tricked into traveling to another world (which she is supposed to save) but among the first things she finds there is a magical rune that teleports her back to London. [[JumpedAtTheCall Not that she wants to]], since her home is a ''very'' dull place, constituting one bleak location among hundreds found in the game.
* This is the premise of ''VideoGame/{{Myst}}'', in which the player stumbles across a mysterious series of worlds after accidentally using a Linking Book. Actually, even if you win the game, you don't get to go home. In the opening of the sequel, ''Riven'', Atrus promises that, if all goes well, he might be able to send the player home. Subverted in Myst III and IV, where the player willfully returns to visit Atrus.
** It's implied at the end of ''Riven'' that when Atrus [[spoiler:drops his D'ni Linking Book into the Star Fissure]], he's leaving the player with both a way home and a means to visit him. This was before D'ni turned out to be [[spoiler:EarthAllAlong]].

* In the first ''VideoGame/{{Persona}}'' game, the party ends up spending a good deal of the game in an [[AlternateUniverse alternate version]] of their city. [[spoiler:It eventually becomes a non-subversion: they were actually trapped in Maki's mind (they've just defeated Kandori in the real world when they learn this). Now, Maki herself has been acting strangely since the whole crisis began, and told the group she was from the Alternate Universe they were in- [[BreakTheCutie oh,]] [[HeroicBSOD crap.]]]]

* Some of the [[AllThereInTheManual supplemental material]] for ''VideoGame/{{Touhou}}'' states that people quite frequently fall into Gensokyo from our world. Apparently the Great Hakurei Border is not absolutely impermeable.

* ''VisualNovel/YamiToBoushiToHonNoTabibito'' (although in this case it's more like "trapped in several worlds").
* ''VideoGame/RuleOfRose''.
* A recurring theme of ''VideoGame/SuperRobotWars'' since ''VideoGame/SuperRobotWarsAlpha Gaiden'', since it's the easiest way to put shows that have totally contrasting worlds and backgrounds together.
* In ''VideoGame/ShinMegamiTenseiIV'', this is what happens once the Yamato Perpetual Reactor is turned on. The three Samurai are desperate to go home, but the only way back is turning on the Reactor again in the parallel worlds. [[spoiler: This is a trap engineered by the White, to show the {{Crapsack World}}s that could arise from choosing pure Law or pure Chaos, in an effort to have TheHero MercyKill the multiverse by overloading the reactor and creating a massive black hole to "return all to nothing".]]
* Luigi is accidentally summoned to the Bears' World in ''[[VideoGame/{{Something}} Something Else]]'' because they wanted his brother, Mario.
* The main character from OutOfThisWorld has this happen to him, being transported to a distant planet, or possibly a different dimension when lightning strikes him in his lab one evening. As seen in the sequel, ''Heart Of the Alien'', he never makes it back.
* In ''VideoGame/LufiaCurseOfTheSinistrals'', [[spoiler:Dekar is thrown into a hellish otherworld through a HeroicSacrifice. He fights his way out, ''blows up the entire dimension behind him'', and gets back to the party in time to save the day.]]
* Happens in all of the video games in the ''Franchise/SilentHill'' series, with the protgaonists trapped in one or more alternate dimensions centered around the titular town and its surrounding environs. Overlaps with ClosedCircle, since the alternate version of the town is also physically cut off from the rest of the world.
* In ''VideoGame/SuperRobotWarsBX'', the ruins on Austral Island somehow sends the protagonist's group to [[Anime/PanzerWorldGalient Arst]], leaving them stranded on an alien world for a few scenarios.
* This is the premise of ''VideoGame/RakenzarnTales''. The main character, Kyuu, is an ordinary student who's sent in the ConstructedWorld of Rakenzarn by the local InterdimensionalTravelDevice. Rakenzarn is a fantasy world with everything you would expect from a fantasy world in a RPG (guns, swordfights, magic, monsters and of course the local BigBad trying to take over the world...). So, Kyuu has to learn and train in order to adapt to this new world and to survive. In Chapter 5, after being [[spoiler:sent back to his own world, he has the choice to return to Rakenzarn, this time willingly]].
* In ''VideoGame/HolyUmbrella'', the adventure begins as the protagonist picks up a mysterious umbrella and is instantly transported into the fantasy world of Margence.
-->[[LampshadeHanging "Hold on! You don't mean I've ended up in another world, like in a cartoon or a game?!"]]
* ''VideoGame/WarioLand3'' starts with Wario finding a music box in a cave, which suck him into another world. The god of said world promises to return Wario home if he can find the [[MacGuffin five music boxes]].

* ''VideoGame/OneShot'' has Niko waking up in a dark world, designated as the world's [[TheChosenOne messiah]]. Unfortunately, while everyone seems to know what Niko is there for, they aren't so sure how to get them home - a process that ends up being rather difficult.

* Lucco in ''Webcomic/{{Fite}}'' [[spoiler:though it's actually a JourneyToTheCenterOfTheMind]].
* The whole plot of ''Webcomic/{{Miamaska}}'', as Amity and Guere are stuck there.
* ''Webcomic/{{Homestuck}}:'' Anybody who plays SBURB will be transported into the Incipisphere. However, the series is more of a {{Deconstruction}} of the trope, as the home planet and eventually the universe of the players is destroyed once they leave.
* The plight of the titular characters in ''Webcomic/BobAndGeorge'', but eventually one character even points out that they are not from any megaman dimension, but nobody seems to care anymore. [[http://www.bobandgeorge.com/archives/001230c Given that it was actually a conspiracy to do it to Bob, and he tried to do it to George in revenge. . . .]]
** Earlier [[http://www.bobandgeorge.com/archives/000514c The Author is trapped in the comic]] -- though, [[CursedWithAwesome he realizes]], this means StuffBlowingUp.

* [[http://www.penny-arcade.com/comic/2013/02/01 This comic]] from ''Webcomic/PennyArcade'' suggests this type of plot for the in-development ''Film/WarCraft2016'' film, as well as demonstrating other tropes such as the JerkJock, TheCheerleader, and the LovableNerd who [[IChooseToStay chooses to stay behind in the end.]]
* ''Webcomic/AtArmsLength'': A new character was introduced, coming from another reality. Sadly, nobody knows how he got there, aside from him just appearing on a roof top, or how to send him back. In the mean time, he will be disguised as a native, and is technically an AlienAmongUs as well.

* In ''Webcomic/GoodbyeToHalos'' the main character was send through a portal to another world by her father, with no idea how to reopen the portal to get back.

[[folder:Web Original]]
* While their trip to Creturia was intentional, the Dimensional Guardians from the web fiction serial ''Literature/DimensionHeroes'' find themselves trapped in the world until they can find the objects they need to both save the world and return home.
* The serial web novel ''Literature/{{Elcenia}}'' starts out with protagonist Rhysel being [[InconvenientSummons summoned]] to the titular MagicalLand. Unusual in that Rhysel is from a different MagicalLand herself.
* This happens in the gender bender Literature/TheFiniteLifeOfADatingSimHeroine to the main character Michio, which takes place in the titular dating sim.
* This setting is currently the most popular for [[{{crossover}} multifandom]] JournalRoleplay Games. The community has even coined a phrase for games based around this setting--"spooky jamjar". Which has now come full circle- meet Roleplay/{{Roleplayedingly}}. A roleplay where the characters are sent to a new world every week- and every world is an ''existing Website/LiveJournal roleplay''.
* The heroes of ''Literature/TheDragonWarsSaga'' are examples, although it's insinuated they could leave if they knew how and really wanted to do so.
* In ''Literature/TrintonChronicles'' very first story (''Fantasia''), all of the characters end up in a portion of the [[MagicalLand Fairy Realm]] or something similar.
* According to RobertBrockway of ''Website/{{Cracked}}'', the need for a "straight man" in a MagicalLand story is one of the [[http://www.cracked.com/blog/4-realizations-that-will-ruin-science-fiction-you/ 4 Realizations That Will Ruin Science Fiction for You.]]

* In ''Literature/{{Cradleland}}'', a passenger airliner is transported by a portal to another planet.
* The Travelers of ''Literature/{{Worm}}'' are eventually revealed to be an example of this trope seen from the other side.

In their search for a way home, they became supervillains, and cause a great many deaths, eventually culminating in Noelle going on a rampage that sees dozens of superheroes dead. In the end, only four of the original seven get to go home.
* This is the central premise of Literature/TheLayOfPaulTwister: the main character is from Earth, and he doesn't know how or why he ended up stuck in a MagicalLand, but [[StandardFantasySetting with technology just barely at early Renaissance levels,]] most of his modern skills aren't applicable to society, so he has to [[{{Picaresque}} live by his wits as a rogue of sorts]] to get by...
* Parodied in Website/TheOnion's [[http://www.theonion.com/article/investigators-first-48-hours-most-critical-locatin-53174 Investigators: First 48 Hours Most Critical In Locating Missing Children Who Entered Portal To Fantastical World]], which expounds tips to parents for finding children who are already inside one of these before it's too late and advice to prevent this situation from occurring altogether.
-->''"'When Elizabeth and William went out to play in the garden one day last summer, I thought it would only be a matter of time before they came home hungry for supper,' said Tabitha Newsom, whose children went missing after crawling through a hollow log into a world where everything is made of gemstones. 'But once Id contacted the authorities, they had already been enlisted to lead the Army Of The Seven Pendants and were embroiled in a tense battle with the Ruby Kingdom...I never should have allowed them to follow that giant, glimmering butterfly'"''
* Happens to Geo in ''WebOriginal/GwainSaga'', but he takes it well.

[[folder:Western Animation]]
* ''WesternAnimation/SamuraiJack'' takes this to extremes, by placing a Samurai from feudal Japan in a far-future sci-fi world populated by countless alien races.
* ''WesternAnimation/DungeonsAndDragons'': One weird rollercoaster ride later, and the kids are in world resembling a D&D campaign setting.
* ''WesternAnimation/CaptainNTheGameMaster'' involved the main character [[AscendedFanboy Kevin Keene]] being sucked into "Videoland", a world where Nintendo games were real (and often very misrepresented in comparison to their actual video game counterparts). Strangely Kevin [[JumpedAtTheCall seems to have no interest in going back to the real world]] and very rarely, if ever, expresses a desire to go home. What must his mother think...
* In ''WesternAnimation/KingArthurAndTheKnightsOfJustice'', Merlin needs replacements for KingArthur and the Knights of the Round Table, who have been captured by the series' BigBad. His odd solution is to bring a contemporary American high school football team (whose quarterback happens to be named Arthur King) to DarkAgeEurope to become Camelot's new defenders.

* Fry from ''{{WesternAnimation/Futurama}}'' gets [[HumanPopsicle frozen]] in 1999 and wakes up 1000 years later. Somewhat [[SubvertedTrope subverted]], in that even with the robots, aliens, mutants, and new technology, TheFuture isn't really all that different.
* Goliath and [[spoiler: the remains of]] his clan in ''{{WesternAnimation/Gargoyles}}'' are trapped in stone for 1000 years, thus arriving in 1994 New York from 994 Scotland.
* An episode of ''WesternAnimation/AdventureTime'' had Finn get transported to another world made entirely out of pillows. (The landscape, the wildlife, the people, etc.) He ended up spending the rest of his life there, forming a family and dying of old age, then somehow got sent back to his world a few minutes after his disappearance, with no memory of his time there. It's left ambiguous as to whether or not this actually happened.
* ''WesternAnimation/OverTheGardenWall'' is about teenage Wirt and his young brother Greg being trapped in a world called The Unknown.

* ''WesternAnimation/{{Kaeloo}}'': At the end of Episode 70, [[spoiler: Mr. Cat manages to get all the AlternateUniverse counterparts back through the PortalDoor and then smashes the door so they can't come back. As it turns out, he got rid of the wrong Kaeloo; now he is stuck with AlternateUniverse!Kaeloo and the AlternateUniverse main four are stuck with Kaeloo.]]
