[-[[caption-width-right:340:When you wish upon a star, your horrifying fever dreams come true.]]-]

The musical number in an animated musical in which the animation stops pretending to depict things that are actually happening in the world of the movie and becomes a more abstract illustration of the music. The Disney [[WhatDoYouMeanItWasntMadeOnDrugs Acid]] Sequence is not as common as it first seems -- they only belong here if they are not explainable -- usually a whacked-out moment of lighting and choreography, sometimes caused by hallucinations. If it is caused by a dream, see DreamBallet. If it is caused by substance abuse, see MushroomSamba.

The Disney Acid Sequence can be used to good comedic effect in movies which break the FourthWall. In general though, if the switch is ''too'' pronounced, be prepared for some genuine NightmareFuel.

Named for the most prolific offender and trend setter, although the phenomenon is not limited to the DisneyAnimatedCanon. It's not even necessarily limited to animated musicals; live-action musicals can also contain one if a musical number goes more surreal than just a random song and dance routine. Some examples here are likely to be inspired by {{Busby Berkeley Number}}s. All examples here are prone to contain DerangedAnimation.

[[folder: Disney Examples, in rough chronological order ]]
* The Hallucinogenic Scene in ''Disney/SnowWhiteAndTheSevenDwarfs'' seems mostly fueled by fear (as she's running through the scary, dark woods). But it's certainly trippy. Being the first animated full length movie, it sets up a great precedent for Disney movies to contain a whole realm of further trippy scenes, even if all we're seeing is the main character's perspective when something gets overwhelming - positive or negative. Somewhere in the movie's early stages, Snow White was actually supposed to have a dream sequence of her future with Prince Charming. Judging by the remaining concept art, they were going to be floating in midair against a starry technicolor rainbow sky. It got scrapped, but was eventually used to end ''Disney/SleepingBeauty''.
* ''Disney/{{Fantasia}}'' is not actually an example, as each musical number is its own [[SurrealMusicVideo separate and self-contained animated sequence]] and not an insert in a larger plot. Nevertheless, it deserves mention for containing many of the usual elements, since each of its segments is to greater or lesser extent an abstract illustration of the music being played. Some segments are more abstract than others. The opening number, "Music/ToccataAndFugueInDMinor", is easily the strongest example. Compare the very straightforward animation for Beethoven's "6th Symphony".
* ''Disney/{{Dumbo}}'' has the most shocking and probably most infamous example, with ''Pink Elephants on Parade''. Dumbo and Timothy Mouse drink water spiked with discarded champagne and hallucinate all these freaky-looking elephants.
-->''I can stand the sight of worms\\
And look at microscopic germs\\
But technicolor pachyderms\\
Is really too much for me! '''[EvilLaugh]'''\\
I am not the type to faint\\
when things are odd or things are quaint\\
but seeing things you know there ain't\\
can certainly give you an awful fright!\\
What a sight!''
** Ironically, "seeing pink elephants" is the slang term for what happens when an alcoholic ''abstains'' from drinking for a long time.
* "Aquarela do Brasil" in ''Disney/SaludosAmigos'', being constantly manipulated by a paintbrush.
* The wartime cartoon "Disney/DerFuehrersFace" has one, set to the title song going faster and faster while, among other things, ammunition flies around and Donald has to make himself into a swastika shape by dancing. Luckily, it was AllJustADream.
* The last act of ''Disney/TheThreeCaballeros'' involves DonaldDuck going through one strange [[RogerRabbitEffect animated/live-action]] musical number after another before climaxing in a mock bullfight, with a costumed Donald as the bull and Panchito as the bullfighter. One DVD edition even calls the closing sequence of the movie "Donald's Surreal Reverie".
* "After You've Gone" from ''Disney/MakeMineMusic'', featuring lots of crazy dancing musical instruments.
* The "Too Good to Be True" segment from ''Disney/FunAndFancyFree'' somewhat counts.
* Two examples from ''Disney/MelodyTime'':
** "Bumble Boogie" is a nightmarish journey through the music world from the POV of a poor bumblebee.
** "Blame It On The Samba". Man, ''trippy'' as hell.
* Pretty much the entire [[AllJustADream dream sequence]] in the latter-day WesternAnimation/{{Pluto|ThePup}} cartoon "Plutopia".
* Most of ''Disney/AliceInWonderland'' is this.
* Much of the semi-{{edu|tainmentShow}}cational WesternAnimation/DonaldDuck short "WesternAnimation/DonaldInMathmagicLand", especially both the opening scene and [[JourneyToTheCenterOfTheMind Donald's mental exercises]].
* The Ride/DisneyThemeParks have quite a few, some borrowed from the movies, others original to the parks such as the "Tomorrow's Child" sequence from the Walter Cronkite version of Spaceship Earth or almost the entirety of the original Journey Into Imagination (which was part of why it was so beloved).
** Some of the ones based on movies include: Alice in Wonderland, Mr. Toad's Wild Ride, Roger Rabbit's Car Toon Spin, and Winnie the Pooh.
* ''Film/BabesInToyland'' has the song "I Can't do the Sum", during which Mary Contrary (played by Annette Funicello) sings mostly on a black background, with [[DoubleVision duplicates]] who flip upside down and sideways while changing colors.
* ''Franchise/WinnieThePooh'' has lots of these:
** The first example that the franchise has to offer is "Heffalumps and Woozles" from ''[[Disney/TheManyAdventuresOfWinnieThePooh Winnie the Pooh and the Blustery Day]]''.
** The ''[[WesternAnimation/TheNewAdventuresOfWinnieThePooh New Adventures]]'' episodes "King of the Beasties", "The Old Switcheroo" and "Eeyore's Tail Tale" each contain one.
** From the holiday specials, we have "I Wanna Scare Myself" from ''Boo to You Too'', "When the Love Bug Bites" from ''A Valentine for You'' and "Easter Day With You" from ''Springtime With Roo''.
** And in ''Pooh's Grand Adventure: The Search For Christopher Robin'' there is Owl's "Adventure Is A Wonderful Thing".
** "Round My Family Tree" from ''The Tigger Movie''.
** "The More I Look Inside" from ''Piglet's Big Movie''.
** "The Horribly Hazardous Heffalumps" from ''Pooh's Heffalump Movie''.
** The "Too Much Honey" song number from ''The Book of Pooh'' story by the same name.
** ''Disney/WinnieThePooh'' has two: "[[TheVillainSucksSong The Backson Song]]", done as a living chalk drawing, and "Everything is Honey", where Pooh is in a world made of honey, including honey clones of himself as backup dancers on the rim of a giant honey pot.
* ''WesternAnimation/TheBraveLittleToaster'' features a song called "Cutting Edge" (aka, "[[RefrainFromAssuming More, More, More]]"), which involves, among other things, a singing table lamp somersaulting through outer space. Of course, this is a movie where ''every'' character is an inanimate object. (We're not sure whether that makes it better or worse.)
** Given that every other musical number happens within the confines of the world around them DESPITE being a shop backroom full of hacked together 'mutant' appliances and the cars in a junkyard being sent to the crusher, Cutting Edge definitely counts as the Acid Sequence.
** Toaster's clown dream also counts, as a terrifying version of the Acid Sequence.
* The [[http://www.youtube.com/watch?v=_70P4c1UVIY opening sequence]] to the Creator/DisneyChannel show ''Series/AdventuresInWonderland'' (made by Eli Noyes, Jr.) certainly qualifies.
* ''Disney/BeautyAndTheBeast'' features "Be Our Guest" ...compared to everything else on this list, it is {{downplayed|Trope}} but one can't deny the sheer craziness of what was quite possibly the most spectacular dinner show ever animated. [[WordOfGod Commentary tracks provided on the dvd]] even ''acknowledge'' that it throws logic out of the window, but the end result was WorthIt.
* ''{{Disney/Aladdin}}'' has "Friend Like Me". Everything [[Creator/RobinWilliams the Genie]] does in that movie counts as an acid sequence.
* ''Disney/TheLionKing'' has the IWantSong, "I Just Can't Wait To Be King".
* ''Disney/TheLionKingIISimbasPride'' has the love song "Upendi".
* ''Disney/TheLionKingOneAndAHalf'' has Timon's song, "That's All I Need" Lampshading it. The sequence of the 'props' sliding out back to the Savannah and the sarcastic applause of the hyenas makes it very clear that, far from a bunch of animals suddenly displaying amazing choreography skills, this is genuine daydreaming/acid consumption territory, but since Timon is awake, it is not actually a dream.
* ''Disney/{{Pocahontas}}'': "Colors of the Wind". It's difficult to say whether the sequence is actually happening (if so, it happened over the course of several days, considering the changes in daylight), or if it's simply an interpretation of the spirit of nature surrounding them.
* ''Disney/TheHunchbackOfNotreDame'': "A Guy Like You". The commentary track references this trope, going so far as to suggest that ''everything'' involving the three gargoyles might have been Quasimodo's imagination. [[FridgeHorror Well, when you spend your whole life alone in a bell tower...]]
* ''WesternAnimation/AGoofyMovie'': The original had "On the Open Road" which included a bunch of girls popping out of a piano, while it's played in the back of a pick up truck and a corpse dancing on a hearse. Being a Goofy movie of course, it's not ''impossible'' that this is actually happening, but it's still pretty trippy.
** ''An Extremely Goofy Movie'' had the nightmare fueling "C'mon Get Happy" sequence, which seemingly suggests an 'experimental phase' when Goofy first went to college in the 70's.
* ''Disney/{{Mulan}}'': Happens in the song "A Girl Worth Fighting For."
* ''WesternAnimation/RecessSchoolsOut'': The cast performing "Green Tamborine" during the credits (this movie was also a huge ShoutOut to TheSixties)
* ''WesternAnimation/TheIncredibles'' [[WhatCouldHaveBeen was to have a]] DreamSequence set to jazz music where Helen Parr dreamt about her husband cheating on her with hundreds of silhouetted, beautiful women in order to highlight her suspicions about her husband's behavior, but it was cut due to length and the fact that they would never get away with so blatantly stating what Helen's fears were in a Disney movie.
* ''Disney/HomeOnTheRange'': The cattle-rustling sequence. Dancing cows, shifting colors, and Randy Quaid yodeling.
* ''Disney/ThePrincessAndTheFrog'' has the song ''Almost There'', which is a very sudden ArtShift into the style of Tiana's restaurant folder. There's also the VillainSong ''Friends on the Other Side'' by Dr. Facilier which has a ''very'' trippy sequence during the "transformation central" portion.
* Just about every song in ''Film/HighSchoolMusical 3'', to some extent. They could have planted an Aesop about not doing drugs into the movie without too much trouble.
* ''WesternAnimation/PhineasAndFerb''
** In addition to being a BigLippedAlligatorMoment and a rare ''canonical'' CaramelldansenVid, {{Animesque}} [[https://www.youtube.com/watch?v=pHpeDctyxE0 J-Pop (Welcome to Tokyo)]] is definitely one. Candace aptly sums up the audience's reaction:
-->'''Candace:''' I have ''no idea'' what just happened.
** In "The Ballad of Badbeard", Candace has a MushroomSamba with moss, so basically almost every scene with her in that episode was her hallucinating.
-->'''Candace, during an otherwise entirely unrelated musical number:''' Why do my nostrils whisper to me?
** And there's [[http://www.youtube.com/watch?v=MRCmLxxOwyM Livin' in a Funhouse]] from "Misperceived Monotreme".
** ''WesternAnimation/PhineasAndFerbTheMovieAcrossThe2ndDimension'' has one as well, maybe more than one, considering how you view them. The song 'Brand New Reality' quickly degenerates into this trope as the song reaches the end and the alternate realities Phineas and the gang pass through get more and more surreal.
** The staff must really enjoy animating these since [[http://www.youtube.com/watch?v=xLLBaVzqmNE&feature=related Going Deep Into Your Mind]] from "Monster From The ID" is another DAS, this time showing us Candace's mind, and it is just as crazy as everyone imagined.
* ''WesternAnimation/WanderOverYonder'' has the sequence beginning with a DrosteImage in "The Box" which of course turns out to be AllJustADream, but it comes from Wander's anxiety of not being able to open the box he's delivering.
** The song "Inside Your Mind" from the episode "The Void" definitely qualifies, due to said void being able to make [[{{Cloudcuckoolander}} Wander's]] imagination real. Multiple technicolor Wanders singing in harmony while each playing different instruments are just the ''beginning''.
* Olaf's song "In Summer" from ''{{Disney/Frozen}}'' is a low-key example, but it's done in a distinctly different style than the rest of the film, involves a lot of anachronisms (e.g., hats from 20th century America), and when Anna and Kristoff appear in it, they both look a little freaked out.
[[/folder]]

[[folder: Other Animated Examples ]]
[[foldercontrol]]

[[folder: Anime ]]

* The Black Four's VillainSong from ''Manga/KimbaTheWhiteLion'' had shades of this.
* Both of the first two ''Anime/DragonBallZ'' movies contain Disney Acid Sequences featuring Gohan. ''Dead Zone'' has "Tenkaichi Gohan" (The World's Greatest Gohan) after Gohan eats [[GRatedDrug an alcoholic apple]], and ''The World's Strongest'' has "Piccolo-san Daisuki" (I love Mr. Piccolo) when he falls asleep while studying. [[BigLippedAlligatorMoment Neither really have anything to do with the movie's overall plot.]]

[[/folder]]

[[folder: Animated Film ]]

* Most of ''WesternAnimation/YellowSubmarine'' is pretty trippy to begin with, but especially "Only a Northern Song", "Lucy in the Sky with Diamonds" and "It's All Too Much".
** [[http://www.youtube.com/watch?v=OSIgC1GWC38#t=3m23s The final scene "It's All Too Much"]] Is an Acid Sequence ''within'' an Acid Sequence (the rest of the movie)!
* ''WesternAnimation/QuestForCamelot'': "If I Didn't Have You", a particularly jarring example because it looks like the kind of short and funny cartoon that Warner Bros. is rightfully better-known for, randomly placed in the middle of what's supposed to be a dramatic epic.
* ''[[WesternAnimation/TheJetsons Jetsons: The Movie]]'': [[http://www.youtube.com/watch?v=hS59H3QP478 "You 'N Me"]] - Judy Jetson and her new boyfriend were in a holographic area that changes with their thoughts.
* [[http://www.youtube.com/watch?v=rQnlkokoIPY "Underwater Fantasy"]] from ''WesternAnimation/{{Animalympics}}''.
* ''WesternAnimation/ThePrinceOfEgypt'': the instrumental part of "All I Ever Wanted" in which hieroglyphs come to life; and "The Plagues", which is the song which goes with most of the plagues, and so days are compressed into minutes - and that split-screen shot at the end of Pharaoh and Moses is done for artistry.
* A few of the musical numbers in ''WesternAnimation/FernGully'', including comic relief character Batty's introduction, and the villain Hexxus's [[VillainSong song]] (both of which have the potential to traumatize children).
** In Ferngully 2, there is the song "Wanna Go Home" - a perfect example since lighting springs from nowhere, cages vanish and animals start dancing.
* [[http://au.youtube.com/watch?v=PbWblYZC3U8 "Big and Loud (part 2)"]], the DarkReprise VillainSong from ''WesternAnimation/CatsDontDance''.
* ''ComicBook/LuckyLuke: The Ballad of the Daltons'' has [[http://www.youtube.com/watch?v=f63mfRtB93Q one]], though it's caused by MushroomSamba.
* ''WesternAnimation/TheSecretOfNIMH 2: Timmy To The Rescue'' has its VillainSong "Just Say Yes", which moves (both in terms of animation and lyrics) so fast that it ends up being a huge MindScrew.
* ''Literature/WatershipDown'':
** The single song is this trope turned up to 11 and manages to be both a TearJerker and horrific at the same time. It helps that Art Garfunkel sings it.
** This may not qualify, as it may actually be happening in-universe. Fiver is psychic and may simply be able to see the Black Rabbit leading him to Hazel.
** Another Acid Sequence occurs at the start of the film - the story of Frith and how rabbits came to be. Holly's retelling of how the [[spoiler:Sandleford warren came to be destroyed]] may also count.
** Every scene shot from the rabbits' perspective is a combination of this trope, ArtShift and fright.
* ''WesternAnimation/RockAndRule'': "My name is Mok! Thanks a lot!" Justified in that the character singing/dreaming it actually IS on acid (and most likely several other drugs as well, the first thing he does when he wakes up is snort something!)
* ''WesternAnimation/ABoyNamedCharlieBrown'' has several crazy musical sequences. The first is a straightforward "Star-Spangled Banner" stars and stripes montage, the second is a crazy nightmare scene with Snoopy fighting the Red Baron, the third is an extended musical number where Linus and Charlie Brown study for a spelling bee with giant letters everywhere, the fourth is a Fantasia-style scene where Schroder plays the piano, the fifth is a nightmarish bus ride to the city (with a hallucinating Linus, who has been deprived of his blanket) and the sixth is a fantasy skating scene with Snoopy.
* Roughly in the middle of ''WesternAnimation/SnoopyComeHome'' there's a trippy montage where multi-colored versions of Snoopy and Woodstock walk through surreal backgrounds to an instrumental version of one of the movie's songs.
* The Creator/DonBluth film ''WesternAnimation/AllDogsGoToHeaven'' contains one where Charlie encounters an over-the-top giant big lipped alligator who sings a bizarre song to him while doing an Esther Williams homage. It's all [[BigLippedAlligatorMoment really weird and has just about nothing to do with the story]], aside from a very brief callback later on.
** The MGM sequel ''WesternAnimation/AllDogsGoToHeaven 2'' features a darker example, as Carface's new ally turns out to be the Devil. During the big VillainSong "It Feels So Good to Be Bad", Red (the Devil character) makes the scenery change several times through each verse. One moment, it's a bizarre hellish barber shop, then a nightmarish roller coaster, and finally something resembling FireAndBrimstoneHell.
** Also from The ''WesternAnimation/AllDogsGoToHeaven'' [[YetAnotherChristmasCarol Christmas Carol]] has [[http://www.youtube.com/watch?v=oWbGm-P5PUY "Clean Up Your Act".]]
* Another Creator/DonBluth film, ''WesternAnimation/{{Anastasia}}'', has the half-remembered, half-imagined dancing sequence in the royal palace, complete with imaginary PimpedOutDress. Plus the VillainSong with the singing and dancing bugs.
** Also on the ship later, Anastasia is seeing butterflies and her family in a pleasant meadow while, in actuality, she is on a ship in a storm. Quickly changes to horror when [[spoiler: her family and the pleasant meadow turn into demons and hell, respectively]]. This is just one of many attempts that the BigBad tries to employ to destroy her, but still.
* The [[http://www.youtube.com/watch?v=Bjj_94ECUKU committee song]] from ''Babar: The Movie''.
* [[http://www.youtube.com/watch?v=S6DOxuucAEk Nigel's]] VillainSong in ''WesternAnimation/{{Rio}}''.
* In ''WesternAnimation/BeavisAndButtHeadDoAmerica'', Beavis eats a peyote cactus while in the desert and experiences a surreal animated music video for White Zombie's "Ratfinks, Suicide Tanks and Cannibal Girls". Animated by band member Music/RobZombie, no less. Creator/MikeJudge didn't want to have this scene in the movie in the first place. Creator/{{MTV}} wanted a music video somewhere in the movie similar to the TV series, but Judge thought that would stop the plot dead and compromised with the hallucination sequence. It was still awesome though.
* A couple musical numbers from the [[Creator/RankinBassProductions Rankin-Bass]] TV specials of ''WesternAnimation/TheHobbit'' and ''WesternAnimation/TheReturnOfTheKing'' certainly qualify…
* Templeton the Rat's song about the fair in the animated musical adaptation of ''Literature/CharlottesWeb'' was rather trippy.
** More notably, the title song after Charlotte's lullabye to Wilbur is a more trippy moment.
* Literally true in the stoned space-travel portion of "So Beautiful And So Dangerous", a segment of ''WesternAnimation/HeavyMetal''.
* ''[[WesternAnimation/TheFlintstones The Man Called Flintstone]]'' had trippy sequences for the songs ''A Spy-Type Guy'', ''Teammates'', ''Tickle, Toddle'', and ''Someday, we'll do great things''.
* ''Animation/TheElmChantedForest'' has "Truffle Shuffle"- actually, any of the songs in The Elm-Chanted Forest with the exception of "Let Your Fur Down".
* In ''Anime/MindGame'', after [[spoiler: Nishi dies]] the whole movie is like this.
* ''Literature/ThePhantomTollbooth'' contains a scene where Milo tries to conduct the sunrise but winds up making the whole sky go crazy.
* The "[[Music/KatyPerry Firework]]" sequence in ''WesternAnimation/{{Madagascar}} 3''.
* ''WesternAnimation/TheSmurfsAndTheMagicFlute'' had one when Homnibus sends Johan and Peewit on a trip to “The Land of the Smurfs” via Hypnokenesis.
* The "Yellow Submarine"-esque opening sequence in ''[[WesternAnimation/{{Futurama}} Bender's Game]]''.
* The ''Comicbook/{{Asterix}}'' animated films sometimes do these. These animators are crazy!
** ''Asterix and Cleopatra'': Obelix, hungry and in the desert, dreams [[http://youtu.be/HwYVO1TtWaI?t=29m45s 'When You're Eating Well You're Well']]
** ''Asterix and the Big Fight'': Cacophonix tries to restores Getafix's memories with a song, and somehow morphs the sequence into a ''[[http://www.youtube.com/watch?v=lGNHjgWsA04 rock and roll music video]]''. This time, there's no excuse, except to illustrate how abnormal Cacophonix's singing is.
** "Pleasure Island" in ''The Twelve Tasks of Asterix''.
** ''The Big Fight'' has a bard song rendered as a trippy rock number, but the viewpoint character is ''really'' hallucinating.
* In ''TheRoadToElDorado'', ''[[http://www.youtube.com/watch?v=yYprdmE1dFc It's Tough To Be A God]]'' enters acid sequence territory towards the end; it's implied that the characters singing the song have become intoxicated.
* In the 2012 adaptation of ''[[WesternAnimation/TheLorax The Lorax]]'', the Once-ler's VillainSong uses images that would seem rather improbable if taken literally, such as trees being felled by noise from a gigantic set of speakers or the Once-ler sprinkling pepper on the Lorax as if to eat him while singing about survival of the fittest, to metaphorically depict the growth of the Once-ler's company and his increasing self-delusion.

[[/folder]]

[[folder: Western Animation ]]

* The ''WesternAnimation/DextersLaboratory'' episode "Aye Aye Eyes" contains a 70's style psychedelic musical number.
* The 1977 Creator/DrSeuss special ''WesternAnimation/HalloweenIsGrinchNight'' has a major example, the [[SignatureScene infamous]] [[http://www.youtube.com/watch?v=KeFaBvL72a8 Paraphernalia Wagon]].
* There is an acid sequence towards the end of ''WesternAnimation/TheGrinchGrinchesTheCatInTheHat'', courtesy of the Grinch. This acid trip was played on the Cat while some very unfitting and wild Dixieland music played.
* Almost the entire 1946 WesternAnimation/LooneyTunes cartoon "The Big Snooze" (the last one to be directed by Creator/BobClampett) consists of a crazy dream sequence of Elmer Fudd's that he has when BugsBunny invades this dream and turns it into a nightmare in order to make him return to working with Creator/WarnerBros and with Bugs.
--> '''Elmer:''' *bombarded by various weird designs of rabbits* Biwwions and twiwwions of wabbits! Where are they all coming fwom?!
--> '''Bugs:''' From me, doc! *playing with an adding machine that releases the rabbits* I'm multiplying, see? I'm multiplying!
* Somehow, when Creator/HannaBarbera cartoons go weird, they go ''really'' [[DerangedAnimation weird]]. The best single example would be the fever dream-esque musical sequences in the already very strange ''Galaxy Goof-Ups'' (the adventures of Yogi Bear and Huckleberry Hound and a couple of [[TheScrappy wacky new characters]]... [[WereStillRelevantDammit but they're in space]]!). Every so often, the plot would stall for a minute or two and they would go disco-dancing for no apparent reason.
** The lesser-known HB cartoon ''WesternAnimation/TheCattanoogaCats'' sometimes went pretty trippy during the Cats' musical numbers, particularly [[http://www.youtube.com/watch?v=fQFTxOEE1Tc "I Wish I Was a Fire"]] and [[http://www.youtube.com/watch?v=d7SuCwYLiH8 "Hoot Hoot Owl"]] (the latter has cut-out animation sequences, a major departure from usual HB work).
** The song "Eep Opp Ork Ah-Ah" from ''WesternAnimation/TheJetsons'' episode "A Date with Jet Screamer"
* Most of [[Creator/MaxAndDaveFleischer Fleischer Studio]]'s early cartoons are made of this, so much so that this trope should be named after them. Don't believe me? Look up "Minnie The Moocher", "Swing You Sinners" and the Betty Boop version of "Snow White". Go on. We'll wait.
** "WesternAnimation/BimbosInitiation". You have to wonder if the many burning (hemp) ropes we see in Fleischer films really are a now-obscure reference to weed.
* The infamous TV special "It's Your First Kiss, Charlie Brown" (featuring Heather, aka the [[{{Canon}} non-canonical]] Little Red Haired Girl), has Charlie Brown experience one of these after the eponymous first kiss. [[spoiler: Unfortunately, because of it, Charlie Brown [[NoodleIncident doesn't remember anything else that happened after]], despite Linus explaining in detail just [[OffscreenMomentOfAwesome how damn cool it was]].]]
* One can't mention Peanuts acid sequences without mentioning the [[http://www.youtube.com/watch?v=5nXl93ji30M "eponymous song"]] from "It's Flashbeagle, Charlie Brown."
* Although it's sometimes [[CutSong cut from TV showings now]], Rankin-Bass Christmas classic ''WesternAnimation/SantaClausIsCominToTown'' has one sung by [[HotLibrarian Jessica/Mrs. Claus]] as she lets down her hair to reveal herself as BeautifulAllAlong; it's got lots of floating bubbles of color (this ''was'' TheSixties[[note]]Well, technically it was 1970.[[/note]], after all).
** Between Jessica's song and Chris's song when he first starts giving out gifts ("If you sit in my lap today/ a kiss a toy is the price you'll pay"), both Santa and Mrs. Claus can both be seen to be fairly unwholesome.
* The 1972 Depatie-Freleng special version of ''WesternAnimation/TheCatInTheHat'' had two sequences in it, one for the song "I'm a Punk", and another for "A Cat in a Hat"
* The ''WesternAnimation/DonkeyKongCountry'' TV series' musical numbers tend to vary between these, [[BigLippedAlligatorMoment Big-Lipped Alligator Moments]] and normal musical numbers. A bit of a variation, since they usually refer to the plot (or current scene) within the episodes.
* The "Bunyip" song sequence from the 1970s Australian "Animated characters on live action backgrounds" film ''WesternAnimation/DotAndTheKangaroo''.
* One episode of ''WesternAnimation/TheRenAndStimpyShow'' involves Stimpy getting [[BodyHorror sucked inside his own belly-button]], accompanied by a sequence with trippy images and an acid rock influenced song.
* The 1971 animated feature ''WesternAnimation/ThePoint'', about the round-headed boy Oblio and his dog Arrow, has several. It helps that, according to [[http://en.wikipedia.org/wiki/The_Point! the Other Wiki]] composer Music/HarryNilsson was on acid when the original idea came to him.
* ''WesternAnimation/TheSimpsons''
** The ending (and closing credits) of "[[Recap/TheSimpsonsS10E6DohInTheWind D'oh-in in the Wind]]".
** A number of extended musical dream sequences from definitely qualify, for instance Homer in the Land of Chocolate in "Burns Verkaufen Der Kraftwerk", Lisa's laughing gas-induced Purple Submersible hallucination in "Last Exit to Springfield" and the hauntingly poetic "Little Nemo" hommage an overworked Homer drops into when he falls asleep at the wheel in "Lisa's Pony". Speaking of the latter, ''Little Nemo in Slumberland'' and ''Dreams of a Rarebit Fiend'' would also easily qualify if they were set to music.
* ''WesternAnimation/GarfieldAndFriends'' would often have one accompanying a song number in one of the ThreeShorts (or sometimes two of the ThreeShorts). A good example would be the DreamBallet known as "What Harm Can It Do?".
* ''El Cubo Mágico'', the sequel to ''DragonHill'', features one of these. Made in flash (in contrast to the otherwise traditionally animated movie, as well as ConspicuousCGI), this scene easily combines DerangedAnimation with horrible music and very confusing imagery, mostly focusing on the boy Kevin trying to beat up a wood viking (and losing teeth in the process), [[spoiler: and later the wood viking starts walking and dancing even though it was pretty much beaten up by the protagonists. Yeah...]]
* ''WesternAnimation/FamilyGuy'' has the episode where Brian takes care of a cranky old lady who has not been out of her house for 30 years and sings a song about all the things she still has to see that has happened in the world - the scenery changes constantly through the song, though it isn't all that "trippy" really.
** A later episode has Brian experiencing a literal acid sequence, as he did mushrooms and went into a world full of strange creatures and hallucinations (and Peter being cooked on a spit naked while singing "The Wheels on the Bus Go Round and Round").
* ''WesternAnimation/TheAngryBeavers'' had one of these in the episode where Norbert meets Treeflower at a Woodstock-like rock concert: http://www.youtube.com/watch?v=CW_JzMsYVyY
* There are several extremely acid-soaked sequences in the independent animated film ''WesternAnimation/SitaSingsTheBlues''.
* The [[http://www.youtube.com/watch?v=GAYakGJ1fXU party song]] from ''[[KatyCaterpillar Katy the Caterpillar]]''.
* "What's not to Love" from the New York episode of [[WesternAnimation/TotalDrama Total Drama World Tour]] definitely counts.
** "The fun is funner, the bagles are bagler, the bums are bummer..."
** The crayon drawn "Oh Izzy" love song sung by Owen
* Any of the songs from the "Rupert and the Frog Song" VHS. Especially [[http://www.youtube.com/watch?v=prH0Y4ex_m0 "Oriental Night fish"]] which has also been a source of nightmare fuel for many viewers.
* ''WesternAnimation/{{Metalocalypse}}'': Any time that Toki Wartooth decides to sing a solo, this is guaranteed to happen. So far we have:
** "Underwater Friends", an [[Music/TheBeatles Octopus' Garden]]-esque sequence where he sings to the fishes surrounding him in his immersion tank.
** "[[http://www.youtube.com/watch?v=uD0qyXMjb1s No More Hamburger Time]]" a song sung [[spoiler: to his dead cat]] that starts out [[SugarWiki/HeartwarmingMoments surprisingly heartfelt]]...and then quickly devolves into madness when the rest of the band joins in.
** "I Am Toki", an autotuned song sung as Toki goes to meet his Internet lifemate. The dream sequence includes Toki transforming into a knight to rescue a hot princess in a castle from a giant green dragon who bleeds Lucky Charms marshmallows. And then there's a wedding where [[ItMakesSenseInContext the minister and all the guests are rabbits]]. This [[CaptainObvious does not]] [[FanDisservice happen]].
** Similarly, a LittlestCancerPatient fan who wants to meet Toki sends him a DVD of her singing a sweet song about wanting to be brutal - it segues into her and Toki singing and flying together, backed up by a chorus of candy-colored {{Eldritch Abomination}}s.
** Likewise his song, "I Believe" for ''WesternAnimation/MetalocalypseTheDoomStarRequiem''
* In the "Jingle Fever" episode of ''WesternAnimation/FanboyAndChumChum'', the two have a rather surreal [[http://www.youtube.com/watch?v=LwXabd22ss8#t=8m28s musical number about living at a convenience store.]]
** Here's the ''VideoGame/AngryBirds'' [[http://www.youtube.com/watch?v=XcbRgr4dt6I version.]]
* The weird, not so great crossover movie 'Porky and Daffy Meet The Groovie Goolies' has a very trippy sequence called [[http://www.youtube.com/watch?v=hIP36Rc_CIo 'Mad Mirror Land']] wherein the three lead Goolies pursue the Big Bad into [[spoiler: the real world, at least in some respects. Things actually become MORE cartoon-like when in the real world.]]
* The [[http://www.youtube.com/watch?v=2D4ktI1Ixwg Roba rap]] in ''WesternAnimation/TheProblemSolverz'' episode "Magic Clock".
* [[http://www.youtube.com/watch?v=P4TedkQP_hM Call Upon the Sea Ponies]] from ''Franchise/MyLittlePony: [[WesternAnimation/MyLittlePonyTVSpecials Rescue from Midnight Castle]]''.
* The entire episode of "Note-Ablly Pink" in ''[[WesternAnimation/ThePinkPanther Pink Panther and Pals]]''.
* "[[http://www.youtube.com/watch?v=9Z-NbQvhzKM&list=FL6xfuw_Daaio&index=1 La Seine]]" from ''[[WesternAnimation/AMonsterInParis Un Monstre à Paris/A Monster In Paris]]'' turns into one partway through, whereupon Francoeur and Lucille go from dancing on a stage, to dancing on a pier, in the air, and finally on top of the Eiffel Tower.
* The iconic "Walking in the Air" sequence from ''ComicBook/TheSnowman'' is an inversion, as it's pretty normal, albeit with very beautiful animation.
* ''WesternAnimation/RegularShow'' had a scene in "Weekend at Benson's" where the guys drink the Mississippi Queen, a drink [[BlazingInfernoHellfireSauce so impossibly spicy]] that it caused Mordecai, Rigby and Benson [[MushroomSamba to hallucinate wildly]] while the ''Mountain'' song "Mississippi Queen" played.
* In the ''WesternAnimation/TinyToonAdventures'' episode "It's Never Too Late to Loon", Plucky Duck had to study hard for a math test the following day, and he begs Shirley the Loon to use her psychic powers to let him channel the intellect of Albert Einstein. What follows is a scene [[ShoutOut reminiscent of]] the "Pink Elephants on Parade" sequence from ''Dumbo'', complete with several Einsteins running around the screen until they collide with each other and explode, doing a waltz, squirting water like a fountain, before finally turning into cars that drive around for a while until they explode again, ending the dream and causing Plucky to wake up dressed like Einstein.
-->Albert Einstein, Albert Einstein
-->MC squared, MC squared
-->Relatively thinking, he just stands there thinking
-->MC squared, MC squared, MC squared, MC squared...
* Almost any song in ''WesternAnimation/TeamUmizoomi'' will have certain elements of this trope that relate to the song. (i.e. [[http://www.nickjr.com/kids-videos/umizoomi-snack-patterns.html The Snack Patterns Song]])
* The "[[Music/KatyPerry Firework]]" sequence in ''WesternAnimation/{{Madagascar}} 3''.
* ''WesternAnimation/GrandmaGotRunOverByAReindeer'' has two: Grandpa's song and Cousin Mel's villain song.
* ''WesternAnimation/BatmanTheBraveAndTheBold'''s AnimatedAdaptation of ''ComicBook/EmperorJoker'' has one, courtesy of SelfDemonstrating/TheJoker in his VillainSong, "WheresTheFunInThat". It starts off with the Joker playing an electric guitar that came out of nowhere in the blackness, and as he starts singing with a microphone that also appears out of nowhere, the scene shifts to the prison cell and on to the Bat-Signal, where he uses his {{Impossible Shadow Puppet|s}} with his hands to devour the bat shape while on top of the beacon. He then suddenly [[AttackOfThe50FootWhatever grows to monster size and attacks the town]]; makes toys out of police vehicles and monsters out of buildings in a manner worthy of ''WesternAnimation/TheTick''; uses AlphabetArchitecture to spell out "Joker"; and {{dance|ofRomance}}s with the giant Lady Justice statue before dropping her into the water. He then flies upward into the universe, where [[DefaceOfTheMoon his face appears on both the Earth and the moon and the supernova]] before ApocalypseHow Class X-4 is enacted by the latter's kamikaze attack, destroying the universe and leaving a white form where it used to be. A chained-up Batman appears out of the void before the Joker himself approaches behind him, and then his henchmen appear along with Harley Quinn, doing a dance routine worthy of ''Film/TheRockyHorrorPictureShow'', and it gets even freakier when the Joker recreates the universe using playing cards and sends Batman into the iron maiden near the {{Rube Goldberg|Device}} DeathTrap in front of Bat-Mite and Joker-Mite (who uses the former as a stringed mannequin) as the song is coming to a close. [[https://www.youtube.com/watch?v=F4zlC8jAISk This video has to be seen to be believed.]] Justified, as Joker had just became a RealityWarper.
* ''WesternAnimation/GaryAndMike'' - In the third episode, Gary winds up eating a brownie spiked with acid and has a very trippy one.
* In ''WesternAnimation/AnimatedTalesoftheWorld,'' there was a song segment in the Chinese story ''The Magic Paintbrush'' where a young boy, who could paint images that come to life, was riding on a dragon while painting images that came to life.
* ''MyLittlePonyEquestriaGirlsRainbowRocks'' has this in [[https://www.youtube.com/watch?v=qh7j1qUaGOc DJ PON3's animated short]].

[[folder: Other examples]]

[[/folder]]

[[folder: Film ]]

* ''Theatre/{{Hair}}'' (the film and the musical) has a literal acid sequence in it.
* ''Film/PercyJacksonAndTheOlympians'': Percy, Annabeth, and Grover experience one of these set to the song ''Poker Face'' by LadyGaga after ingesting lotus flowers at the Lotus Casino.
* ''Film/MaVieEnRose'' has one; it involves a popular dress-up doll.
* The musical ''Film/SinginInTheRain'' includes a rare example of a live-action Disney Acid Sequence with the "Broadway Melody" segment, which apparently takes place entirely in Don Lockwood's imagination. After the sequence ends his producer says "It sounds good, but I'd need to see it on film."
* In a similar vein, most of the big production numbers in the musical version of "Kiss of the Spider Woman" take place in Louis Molina's head. Indeed, any time the title character appears on stage she's probably a figment of his imagination.
* Every musical number in the film version of ''Film/{{Chicago}}'', except for those which are already explicitly set on a stage, happens inside Roxy Hart's head.
* Likewise the musical numbers in ''Pennies from Heaven'' which are almost all in Steve Martin's head.
** Unless it's the original BBC TV series, in which case they're all in Bob Hoskins' head.
* ''Film/MoulinRouge'' is full of this. Even the numbers explicitly set onstage would be impossible to perform live with such lavish effects.
** Also, the duet that begins with "Your Song" was actually cut to make it less Acid Sequence; besides the singing moon, there were twirling soprano stars. Imagine a scene so Acidic that Baz Luhrmann thought it needed toning down!
** Possibly justified seeing how the main characters (and a few part goers) drunk absinthe shorty before the number ''Can-can/Lady Marmalade''.
* Any of the animated sequences in Music/PinkFloyd's ''Music/TheWall'', where most of the second act takes place inside the protagonist's mind anyway.
* Live action example: ''Film/{{Grease}}'', specifically the song "Beauty School Dropout", which is the climax of the movie's C-plot. Features ''Frankie Avalon'' and white-clad dancers out of nowhere - interacting with the subject of the song personally - along with an abrupt setting change. Similarly, the "Turn Back the Hands of Time" number in ''Film/{{Grease 2}}'', which takes place when Stephanie apparently spaces out in the middle of the talent show and imagines singing a duet with the spirit of her MysteriousProtector in what we can only take to be Biker Heaven. Except that when Stephanie returns to reality at the end of the number, the audience is applauding and she's won the talent show, leaving us to wonder if they all somehow experienced the whole sequence with her. And, if not, then who was really singing the male part of the duet while she was tripping out?
* The VillainRecruitmentSong "That's Motivation" in ''Film/AbsoluteBeginners'' (1986) is presented in this manner. The villain in question (played by Music/DavidBowie, who also wrote the song) is an advertising executive who sees his work as selling dreams, and he's encouraging the idealistic photographer hero to become part of his all-style, no-substance world.
* The 1969 movie, ''Film/TheMagicChristian'', has several of these.
* The tour in ''Film/WillyWonkaAndTheChocolateFactory'' has one of these for the characters: while most of the tour involves going around a wacky candy factory (like one would in a tour), the tunnel sequence is something else ''entirely'', as evidenced by the increasing discomfort of the passengers.
-->'''Wonka:''' There's no earthly way of knowing...Which direction we are going...There's no knowing where we're rowing...Or which way the river's flowing...Is it raining? Is it snowing?...Is a hurricane a-blowing?...Not a speck of light is showing so the danger ''must'' be growing...Are the fires of Hell a-glowing?...Is the grisly Reaper mowing?...YES! THE DANGER MUST BE GROWING FOR THE ROWERS KEEP ON ROWING!! AND THEY CERTAINLY AREN'T SHOWING ANY SIGNS THAT THEY ARE SLOWING!!! '''RRRRUUUUUUUUGGHHH!!!!'''
** {{Lampshade|Hanging}}d by Violet Beauregard who asks if the whole tunnel sequence is a "freak out".
* ''Film/AnchormanTheLegendOfRonBurgundy'' has Pleasure Town.
-->'''Ron:''' Look! It's the most glorious rainbow ever!
-->'''Veronica:''' Do me on it!
* In Ken Russell's film adaptation of the stage musical ''The Boy Friend,'' daydreaming by members of the cast and crew often causes the fairly mundane production numbers -- accurately representing what you'd see if you actually went and saw the play in a theater -- to warp into elaborate and surreal fantasies.
* The Floor Show from ''Film/TheRockyHorrorPictureShow''- or the whole damn movie, for that matter. Toss in the audience-participation element, and it's a ''live performance'' example.
* In {{Film/Troll}}, the VillainSong performed by Torok's minions borders on this.
* ''Franchise/TheMuppets''
** The Muppet Babies sequence in ''Film/TheMuppetsTakeManhattan''. A rare example in that the scene in question inspired [[WesternAnimation/MuppetBabies its own series]], which contained its own examples, which makes it the Russian dolls of animated puppets.
** ''Film/TheGreatMuppetCaper'' has Miss Piggy fantasize about being the center of an underwater ballet, in which the film's villain sings-except after returning to reality and learning said villain's TrueColors, she scornfully tells him, "You know what? You can't even sing! Your voice was dubbed!" Then again, the movie had NoFourthWall ''whatsoever'', and she was under considerable emotional duress at the time.
** "Cabin Fever", a musical number in which the entire cast of ''Film/MuppetTreasureIsland'' comes down with OceanMadness. {{Lampshade|Hanging}}d when the only character who mentions it is treated as being crazy.
* ''Literature/FearAndLoathingInLasVegas'' is loaded with these, considering the main protagonist is high on drugs.
* ''Film/MagicalMysteryTour''...roughly the entire movie! There are rarely any sane moments in the film at all!
* The Red Shoes Ballet from ''Film/{{The Red Shoes|1948}}'': at first it makes sense as a literal ballet and reflection of the protagonist's inner turmoil, and then she grand jetés into surreal land.
* Film/SpeedRacer veers off the track into acid territory several times.
* Several musical numbers from ''The5000FingersOfDrT'' by Creator/DrSeuss (1953) but particularly the [[BusbyBerkeleyNumber Dungeon Orchestra scene]] and the "[[RealMenWearPink Dress Me,]] [[http://www.youtube.com/watch?v=W8TQOzyCu8Q Dress Me" song]]. During the dance number involving the rollerskating, siamese-bearded twins, the hero downs a swig of some "[[LampshadeHanging powerful stuff]]" beforehand.
* Though primarily live action, ''Film/{{Xanadu}}'' still manages to include an ''[[http://www.youtube.com/watch?v=_DiZeVptAoM animated]]'' Acid Sequence that's animated by none other than Creator/DonBluth!
* The first half of "I Want You", "I Am The Walrus", "Being For the Benefit of Mr. Kite", and "Strawberry Fields Forever" in ''Film/AcrossTheUniverse''.
** "I Am The Walrus" and "Being For The Benefit Of Mr. Kite" can be somewhat justified given the substances they were undoubtedly on at that point. Creator/EddieIzzard's performance in the latter definitely turns the notch up to 11, though.
** Likewise, the number "Happiness is a Warm Gun" is a justified Acid Sequence, as Max is in a VR hosptial, and probably high on morphine.
* The Capulet Party sequence in Baz Luhrmann's ''Film/WilliamShakespearesRomeoAndJuliet'' is a literal acid trip. We're left uncertain of whether Mercutio's song and dance number actually happened, or if it was just a byproduct of Romeo being off his face. "Thy drugs are quick" indeed...
* ''Literature/TheWorstWitch''. Creator/TimCurry. The Halloween Song. So [[CrowningMomentOfAwesome amazingly awesome]] it deserves a [[http://x-entertainment.com/messages/435.html play-by-play]]. [[http://www.youtube.com/watch?v=PUhuPn8_d0Q And a link]].
* ''Film/HaroldAndKumarGoToWhiteCastle'': Harold's dream [[ItMakesSenseInContext after being knocked unconscious while riding a cheetah]].
* In ''Film/YouthInRevolt'', after Nick takes 'shrooms. Playing a little loose on the "Disney" part...

[[/folder]]

[[folder: Live Action TV ]]

* In the Music/FlightOfTheConchords TV series this was done a couple of times with some of the more surreal songs in the duo's repertoire. Most notably Pretty Prince Of Parties, which was a literal acid trip.
* Many early episodes of ''Series/SesameStreet'' have a series of sketches on numbers (1 through 10) that involved a baker who holds in his arms that number of desserts but falls down a flight of stairs, ruining the desserts in question. The sketches started with a very flashy animated intro in which the voices of kids are heard counting up from 1 to 10, then back to 1, and finally up to the featured number in the sketch, in choral voice over, while that number, in animated form, zoomed around the screen.
** There's a good chance those were made by John and Faith Hubley of Storyboard Films. [[http://www.youtube.com/results?search_query=John+Hubley+sesame+street They did a lot of Sesame Street and Electric Company video trips]], including [[http://www.youtube.com/watch?v=pLbSongrzEY this beloved classic]].
** Many of the animated sequences were, in some way, acid-y. The Pinball sequences, for example, had a pinball travel through a very large and technicolour pinball machine, while it counted one through twelve. If the lightshows themselves didn't make them trippy, the automatons certainly did. The funky background music probably helped make it more so.
* ''Series/{{Teletubbies}}'' was the first RagdollProductions cartoon to do this.


[[/folder]]

[[folder: Music ]]

* Music/TheWho's {{Tommy}}, pretty much the entire musical. Special mention for the song "The Acid Queen". The movie also does this, as does the stage adaptation sometimes, depending on who's directing.
** "Underture", directly after "Acid Queen", is an instrumental portrayal of the protagonist's acid trip. Since he is blind and deaf and "sees" things as music inside his head, this is actually a justified straight example of this trope.
* Music/{{Autechre}}'s [[http://www.youtube.com/watch?v=nfwD05XA2YQ Gantz Graf]] video. Alex Rutterford, [[WordOfGod the director]], says it was actually inspired by a drug trip.
* The whole music video for Blockhead 's [[http://www.youtube.com/watch?v=QsgFBHfRNq8 The Music Scene]] is a surreal animation.
* Gouryella's [[http://www.youtube.com/watch?v=7Wp7xMwfS3M Walhalla]] video has a freak-out sequence after the {{Black Viking|s}} bumps his head into the camera. [[DemBones Dancing skeletons]] and spinning flowers against a psychedelic hypno-wheel background, etc.
* Future Perfect's [[http://www.youtube.com/watch?v=RAhJVGj_Fv8 "Paradise"]]. The background animation looks like something out of Winamp's Visualization Studio.
* Little Boots' [[http://www.youtube.com/watch?v=McdqerXrwXE "Remedy"]] starts as a PerformanceVideo, then gets all kaleidoscopey.
* The video for Music/DavidGuetta & Music/{{Sia}}'s [[http://www.youtube.com/watch?v=PVzljDmoPVs "She Wolf(Falling to Pieces)"]] does this during the breakdowns.

[[/folder]]

[[folder: Theatre ]]

* Jerome Robbins' comic ballet ''The Concert'' is AllJustADream anyway (more precisely, people daydreaming to music), but the end features all of the characters morphing into butterflies and being chased off the stage by the increasingly irritated [[InteractiveNarrator pianist]].
* "Contact", Angel's DeathSong in ''Theatre/{{RENT}}'', likely a representation of his DyingDream.

[[/folder]]

[[folder: Theme Parks ]]

* Appropriately enough, the Ride/{{Disney|ThemeParks}}land night show ''Theatre/{{Fantasmic}}'' includes one of these, in the form of an updated rendition of the "Pink Elephants on Parade" sequence from ''Disney/{{Dumbo}}''. Although, the entire show could be considered an acid sequence, as it is Mickey's dreams.
* Across the way, Disney California Adventure has its own night show, ''Ride/WorldOfColor'', which could also be considered one big, long acid sequence in action.

[[/folder]]

[[folder: Video Games ]]

* ''VideoGame/TeamFortress2'': "Meet the Pyro" alternates between "Pyroland", a rainbow-filled SugarBowl where the enemy team are FunSize, diaper-wearing fairies, and reality, where RED Pyro singlehandedly murders the BLU team in a gruesome fashion.
* The Arceus event in ''[[VideoGame/PokemonGoldAndSilver Pokémon HeartGold and SoulSilver]]'' treats you to a rather trippy montage of the creation of the universe, set to Arceus's very bizarre and dissonant theme music. This supposedly happens all over again ''every time anything ever is born.'' [[MindScrew Or something.]]
* About ''80%'' (think about it) of ''[[VideoGame/DragonsLair Dragon's Lair II: Time Warp]]'', even if not-that-acid tones.
* ''VideoGame/{{Rez}}'', and its spiritual sequel, ''VideoGame/ChildOfEden''.
* ''VideoGame/BeatHazard'', set to your own music.
* The warp zones in Meteo and Sector X in ''VideoGame/StarFox64''. You go through the gates (in the case of Meteo, ''[[EverythingsBetterWithSpinning while spinning out of control]]''), you end up in a hallucinogenic landscape (spacescape?), and suddenly you're halfway across the Lylat System. Talk about a [[{{Pun}} "wild trip"]]...
** Likewise for [[AnotherDimension Out of This Dimension]] in [[VideoGame/StarFox1 the original]].
* The boss stages in VideoGame/LuigisMansion are rather trippy.
* We've got [[BossCorridor Obani Draco]] in ''RatchetAndClankUpYourArsenal'', which happens to be the home of a {{sadist}}ic [[EvilDiva pop star]] who directly works for the BigBad as his [[TheDragon dragon]]. What makes it an acid sequence is that it's almost completely [[DarkIsEvil dark pink]], contains a giant disco ball, [[spoiler: has a torture chamber]] and all of it's residents are [[AlwaysChaoticEvil evil]].
** Played straight in ''VideoGame/RatchetAndClankSizeMatters'' in "[[NightmareSequence Dreamtime]]".
* One could claim the game ''VideoGame/{{Audiosurf}}'' is just an interactive Disney Acid Sequence.
* A big example of this trope is in the video game The Legend of Zelda: Twilight Princess, in a scene describing the creation of Hyrule. Illia and Link are in a pitch black... space. They then see 3 Dark Links by a tree on a lone random hill in said endless pitch black area. Illia then [[spoiler: grabs a knife tries to KILL LINK]] and Link then [[spoiler:kills Illia with the Master Sword.]] Link then gets [[UncannyValley creepy]] white eyes and joins the dark links. Then about 100 Illias fall from the sky around link and the sequence ends. [[NightmareFuel Holy crap]].
* The whole of the [[{{Defictionalization}} defictionalized}}]] {{urban legend}} ''{{Polybius}}'', including the Game Over screen. As the intro screen warns, people prone to [[EpilepticFlashingLights photosensitive seizures]] should avoid the game.
[[/folder]]

[[folder: Web Original ]]

* This CGI animated video for ''[[http://www.youtube.com/watch?v=igXdVIkPYxY Pink Cadillac]]'' by Jerry Lee Lewis and Music/BruceSpringsteen.
* The final season of "InventionPioneersOfNote" is this.
* Don't Hug Me I'm Scared. ''[[http://www.youtube.com/watch?v=9C_HReR_McQ]]''
* Many of the songs in the ''WebAnimation/CharlieTheUnicorn'' videos.
* WebVideo/TheNostalgiaCritic does one of these in his review for ''Film/{{Junior}}''. In the middle of the review he falls asleep and has a bizarre dream sequence while singing a song about how boring the movie is.
* Without exception, all animation done by youtuber "cyriak" ''[[http://www.youtube.com/user/cyriak channel]]'' qualifies for this trope. See particularly the "Cows and Cows and Cows" Video.
