The old mid-80's Levi's jeans ads, where the Levi's logo would open like a door and various random weird creatures would walk or scurry out. The most memorable were the giant green alien in the samurai armor, and the Tarzan guy wearing jeans who would swing out yelling "Leeeeee-viiiiiiiii's!"
Nickelodeon's old station identification spots from the 1980's.
It's actually not an ad, but more of a one-a-day fact video from Japan starring mameshiba, or "bean dogs". They gross people out with facts, presumably to keep from being eaten. You can find all of the videos subbed here.
Thesecommercials for Zact Lion toothpaste makes you question your state of sanity.
Many elements of Catnapped, particularly Papadoll (a monstrous dog) and Buburina (a freakishly animated evil cat queen). Just check at her freaky eyes and facial expression when she's hypnotizing characters.
In an interview on the disc, one of the creators was asked what his inspiration was. His reply was simply "I'm a Drunkard." Said interview was conducted in a rooftop bar while the group were being served drinks of ever increasing potency. It eventually culminated in what one of the group described as ?detergent?.
Also, in one [adult swim] bumper, they quoted an interview (but didn't say which one) where the producers stated that FLCL is "the type of show we make to let off steam after tackling something like Evangelion."
The Adolescence of Utena (well, the series is like this too, but mostly the movie). It runs like a dream on hallucinogenics. It includes scenes like a morphing butterfly/girl/bedsheet in a cabbage patch and Utena turning into a car. Listening to the director's commentary however, reveals that not only was its creator sober and off drugs, but he's also an incredibly calm, thoughtful individual in general and everything has an allegorical meaning.
Though some of its chapters are breathtakingly or horrifyingly realistic, there are some stories in The Animatrix that just went out of the loop. "Kid's Story" has its moments, but "World Record" and "Matriculated" take the cake in terms of distorted, wild animation.
Puella Magi Madoka Magica The Movie: Rebellion brought back Gekidan Inu Curry, designers of the surreal Art Shift witch labyrinths, and had them do an ever-escalating portion of the visuals. Random flying objects, twitchy paper cut-out animation, and creepy misshapen puppets... the end result is like watching the already trippy original series on acid. Justified in that the whole movie takes place inside a labyrinth, with everything that comes with it.
The guys who made Excel♥Saga had to be hyped on something. Whether it was crack or way too much coffee and not enough sleep is up to you.
Then he goes and makes Puni Puni Poemi, which compresses an even greater amount of insanity into 1/13th of the time.
Excel♥Saga does have some semblance of sense and logic, just as long as you're aware of what all the parodies and references are, what's being satirized, and why. It's not so much some kind of "random for the sake of random" or "on drugs" type of psychedelic trip. (That distinction goes to Bobobo Bobobobo). Excel♥Saga, however, IS one big non-stop barrage of in-jokes poking fun at the director Shinichi Watanabe's own thoughts, feelings, and ludicrous experiences at working in multiple genres of anime, as well as original manga author Koshi Rikudo's cynical, social satire, self-mocking, and controversial statements about his own nation's strange policies and economic troubles. Although the existence of the Puuchuus and why they randomly turn into Takao Saito and Leiji Matsumoto characters when struck with a blunt object? Yeah, I'm not even going to try and explain that.
FLCL, which almost qualifies as a drug in and of itself. Actually, it was. It was the anti-depressant for everyone who had worked on Neon Genesis Evangelion.
And anything else made by Kazuya Tsurumaki. This guy won't ever need drugs — he's crazy enough just as is.
That's because you haven't read the manga, which was definitely made on several substances unknown to mortals and on summoning Salvador Dali's soul after he went through the nine circles of Hell.
Kaiba. The plot summary alone sounds a little out there... And then you see the art style. Kaiba looks like a child's TV show, with trippy architecture and illogical types of technology, gone Cerebus Syndrome and mixed with adult themes. Buildings are depressingly creepy, even with the bright colors and lack of geometric structure. Then you consider how the authorities steal bodies, look into other peoples' personal worlds, execute enemies, have sex, pilot spaceships, HIT BUTTONS AND PRESS LEVERS, etc,.
And Kaiba has nothing on Kemonozume, by the same director. In fact, the art style is actually fairly representative of everything Yuasa (and Studio 4C, for that matter) has done since Mind Game.
And while we're on the subject, Mind Game heavily featured about three or four animation styles, all of them rather...unconventional.
Xxx HO Li C is a wonderful manga, but the art style CLAMP employed does not translate well to video. The anime is fine, but the movie is trippy, surreal, and somehow enjoyable.
Episode 18 of the Axis Powers Hetalia anime. There's no way that the decision to have the Roman Empire randomly pop out of the sea and sing about the differences between heaven and hell was made while sober.
And then there's the movie ("Paint it, White!") where he appears again and sings a rock version (!) of his Heaven and Hell song. It doesn't even make sense in context. ...well, the context itself doesn't really make any sense, either.
Welcome to the NHK has snippets of this in which the protagonist is taunted by appliances.
Trapeze. Oh dear god((s)/dess(es)) Trapeze. A little series about psychiatry at which its own entry notes (legitimately) that it makes viewers fear for their own mental health. Take a novel series about an unusual psychiatrist, mixing it with hallucinogenic vitamin shots, adding one's brains and a major TV announcer, and placing all of these in a blender and setting to "liquefy". And then having a big-name model dress up as a perky-goth nurse and injecting said medicine whilst the doctor leers nearby in a psychedelic fursuit. And this is a Cliff's Notes version of the series BEFORE the True Insanity starts per episode.
CGI series Ga-Ra-Ku-Ta, or Mr. Stain on Junk Alley, which features a hobo named Mr. Stain that finds an object in each episode that royally screws him or his friends up, such as him finding a box of crayons that make anything you draw become real which leads to his friend losing his entire face and begin sucking everything in sight up due to his face becoming a black hole.
It certainly doesn't help that Junk Alley is apparently built above the ruins of a sunken, Lovecraftian city. Though that would probably explain most of the weird, creepy things that happen.
Panty & Stocking with Garterbelt. Ben 10, Invader Zim, Powerpuff Girls - all of the Western cartoons you used to watch were pureed and delivered intravenously directly to the brains of the people behind Dead Leaves and FLCL, then Gainax stuck a pen under their trembling fingers and told them to draw. Unlike most of the other examples, this one was actually influenced by drugs - the creators have admitted that they were drunk off their ass when they came up with the concept for the show.
The Wedding Peach OVA where the Love Angels become cat girls contain EXTREMELY traumatizing images, such as when they go catty over Yanagiba and when they take the forms of the schoolgirl versions, when they innocently move about the wall of the school, yet another Nightmare Face with catty features they don't have anymore until they see Yanagiba.
To put this in perspective, go watch that video linked in the entry for Sayonara, Zetsubou-Sensei. When Madoka gets going, it uses that as a baseline and kicks the pedal through the floor.
Jungle wa Itsumo Hare nochi Guu a.k.a. Hare Nochi Guu is an acid trip from start to finish. The weirdness is too much to state on one paragraph, but suffice to say, the first opening features dancing palm trees and a world inside a stomach. And that's the less weird thing you'll get.
Episode 167 of Naruto Shippuden is this and severe Off Model. In a rare example, it actually works; the episode is a high-speed Chase Fight between two people who are about this close to gods, and the animation emphasises this.
Captain Pronin, a parody of '80s action movies, is exactly what would happen if Mike Judge did meth.
The animation in His Wife Is A Hen is a tad... well, let's start with the boxes that just shrink into thin air after use.
Svetlonos (Torchbearer). A trippy stop-motion animation that features what looks like an ancient Greek hero walking into a set of ruins filled with deadly clockwork traps operated by female statues. Female statues that feel pain when broken. And lets not get into the carnivorous rats that tear apart anything that dies within the ruins, or the mechanized flying creature that spouts artificial blood when defeated or the hideous machine at the end that needs human blood to keep the heavens running.
Everything by Ivan Maximov. For example this thing.
Almost everything done by Marcell Jankovics, but "Son of the White Mare" takes the cake with it's vibrant colors and surreal artistic representation. Let's just look at the Big Bad (a gigantic supercomputer that walks on two legs) and his two lackeys (a Humongous Mecha and a three headed rock monster), who all look completely out of place for what is supposed to be ancient mythology.
It didn't have a spontaneous, unexplained scene where the girl(?) unicorns inflate for no reason at all before returning to their previous forms without seemingly realizing a thing.
Tell me these people aren't on some sort of mind-altering substance. Something is very not right with this.
They're not on drugs. Clearly the two smaller unicorns are just deities hell-bent on ruining Charlie's life with The Genie-esque reality altering visions.
Third one has it the worst. Just look about 30 seconds in.
Jason Steele (the creator) has never done drugs in his life. He's just one crazy bastard... and a damn good singer.
Not quite as surreal as the rest of these, but still disturbing as hell is Pony by the same animator as Kiwi!
Sonic Meets Bon Jovi, where the animator blatantly wasn't trying too much in terms of actually animating the characters. You may also lose sleep over the look on Rouge's face. Then the audio slowed down and became horribly distorted. And then the computer locked up completely.
All of Adidas' Adicolor series are quite odd, but Adicolor Black is completely deranged.
We could make this easy on ourselves and say "Every Disney Acid Sequence EVER". Here are some that stand out:
Fantasia. After the film became a hit among the "head" crowdnote the students who liked to get high on marijuana and LSD, among other drugs on college campuses in the late 60s and early 70s, somebody asked animator Art Babbitt (who animated the dancing mushrooms on that film) if he had been influenced by drugs. He jokingly admitted, "Yes, it is true. I myself was addicted to Ex-Lax and Feenamint."
"Pink Elephants on Parade" Or 'Why elephants shouldn't drink alcohol.' The phrase "pink elephants" refers to hallucinations from too much alcohol consumption.
Saludos Amigos ends with the beautiful, but deranged segment "The Watercolors of Brasil". This is probably the least trippy Disney example, though.
Raggedy Ann & Andy: A Musical Adventure, is the near-legendary Richard Williams' trippy adaptation of the classic children's characters. It includes such madness as a giant taffy-blob monster named The Greedy, who is constantly shoving globs of himself into his mouth, and a diminutive king who inflates whenever he laughs, and is subjected to forced tickling which causes him to swell to immense size. That's not even scratching the surface; watch for yourself and find out...
This version of A Christmas Carol was produced by animation god Chuck Jones and directed by Richard Williams. It is the only version of the story thus far to ever win an Oscar, and deservedly so as it perfectly captures the book's mood. It's barely ever shown on television however, thanks to its trippy and nightmarish imagery. (If the sight of the open-jawed Jacob Marley doesn't scare the piss out of you, the demons living under the robes of the Ghost of Christmas Present will...)
The philosophical film Waking Life is less over the top than most examples on this page, as it is a series of vignettes where people monologue about dreams and philosophical concepts. It does get a bit trippy, sometimes.
The Point! has a musical number about a whale decomposing, a three-faced man, and a talking tree. Unlike most of the other examples, this one was made on drugs. Just watch it.
I Married A Strange Person!. Bill Plympton makes incredibly surreal animation more often than not. He must have started his career after reading a book listing all the rules for animating the human face (chiefly, "don't distort or transform things too much or you'll end up in the Uncanny Valley"), then dedicated his life to breaking all those rules.
Street ofCrocodiles. Stop motion animation that uses things like antique doll parts, machinery, and fresh meat. You have been warned. According with Mark Romanek, that short was one of his major inspirations for the music video of Nine Inch Nails "Closer".
The same can be said about the other shorts made by the Brothers Quay.
It involves a guitar dragon, army skeletons, siren headed policemen and the Beast of the Apocalypse.
Certain pieces of animation by Don Bluth in general qualify, as his aesthetic is largely based in what he learned while working at Disney — but tends to be a lot weirder and full of wacky moon-logic. This argument begins and ends with Rock-A-Doodle.
There are some who have claimed that even A Troll in Central Park is better than you'd think if watched under... certain circumstances. (The plot involves a Fairy creature and his magical plants hanging out in a city park, so don't blame us.)
The "It's Tough to be a God" sequence in The Road to El Dorado, justified because the main characters are implied to be extremely drunk.
Frank Zappa worked with Stop Motion clay animator Bruce Bickford, producing a great deal of animation, which can be seen in Zappa's concert films Baby Snakes and The Dub Room Special, as well as in a film exclusively devoted to Bickford's animation, The Amazing Mr. Bickford. These videos contain images that include Zappa transforming into The Devil, explicit clay figure sexual intercourse and masturbation, mutilation, Gregory Peccary (a pig character from one of Zappa's songs), Zappa being attacked by monsters, and other weird imagery that fluidly morphs into other weird imagery. Bickford has done similarly weird stuff on his own accord. None of it was influenced by drug use, especially not the stuff he did with Zappa, who hated drugs.
Ready, Able by the band Grizzly Bear is absolutely insane, and watching it under the influence of any mind altering substances is either a really awful, or incredibly great idea. The morphing depressed plasticine figures are scary, yet infinitely interesting.
The climax of the short "Wearing of the Grin" is a bit unnerving, to say the least, with Porky Pig being forced to tap-dance in "the Green Shoes" through a surreal landscape as two leprechauns laugh at his misfortune.
The '90s short "Invasion of the Bunny Snatchers" starts out as a pretty standard "Body Snatchers" parody — then goes way off the deep end, using weird cheap animation for the invaders. (Though that was the point. Bugs himself called them "Robot Retreads" while thinking up a way to get things back to normal.)
"The Big Snooze" has Bugs Bunny invading one of Elmer Fudd's dreams and infecting it with some Nightmare Fuel.
Perhaps the strangest and most bizarre animated fare in all of Looney Tunes was "Porky in Wackyland". It's supposed to be bizarre, and they warn you ahead of time, but still, it was definitely over-the-top.
The backgrounds for the cartoon's remake, "Dough for the Do-Do", are even MORE surreal!
Anything made by Bob Clampett is Grade A Certified guaranteed to have at least some degree of this trope.
Particularly in scenes done by Rod Scribner who used a wacky, fast paced, rubbery animation style with often over the top expressions and wild takes.
John and Faith Hubley are masters of this trope.
Eggs (1971) features an argument between Anthropomorphic Personifications of Birth and Death over the future of humanity, and ends with a very strange avian God breaking up the fight. How strange is this GOD? Well, it has three mouths all of which speak in an incoherent dialect which switches from English to Japanese to incomprehensible gibberish in seconds.
Tex Avery's MGM short "The Cat That Hated People" has its title character taking a rocket to the moon and encountering a lot of really weird shit.
Tex Avery in general. The "rules" of Western Animation were pretty well established by the time he came to MGM, and he had a fine time subverting each and every one of them.
The Squirrel Nut Zippers' video for " The Ghost of Stephen Foster" specifically mimics creepy old-timey cartoons like "Balloon Land" and similar, focusing in this case on a couple getting stuck in a haunted hotel.
This "Cosmic Clock" segment from 3-2-1 Contact manages to make geology trippy and unsettling.
The animated music video of Roger Glover's "Love is All" (sometimes known by the album title The Butterfly Ball), which used to pop up on HBO and Nickelodeon in the 80s. Full of crazy transformations, anthropomorphic animals wearing creepy masks, and other examples of why 70s animation was a cesspool of horror (unless you were a weird kid).
Fun fact : French TV watchers did see that music video many, many times. It was used during the Eighties as a fill-in by the 2nd TV channel (there were only 3 in France at the time) when experiencing "technical difficulties". Then some 90's syrup brand used the exact same song and animation on its commercials, which aired between every Saturday morning cartoon at the time. Perhaps it was that singing frog imagery that French people enjoyed so much...
It didn't help that the picture book it was based on was full of detailed paintings which very delicately portrayed the pattern of light and shade hitting an animal's fur. The animators duplicated this effect, then didn't alter it when the animals moved.
And when one is in a bathtub, and the cat has a straw and is drinking the water, it looks like the straw is going up... yeah...
Uh, no it doesn't. Someone has a deranged mind.
The video that Spumco did for Björk's "I Miss You", which is a thoroughly disturbing piece of art (you have to wonder what was going through John Kricfalusi's head when he designed this).
The Yogi Bear special that Kricfalusi did for Cartoon Network. You haven't lived until you've seen Boo-Boo, Yogi, and Cindy each revert to primitive, horrific animals... To be fair, it's only Boo-Boo and Cindy. Yogi never does reform to a primitive, horrific animal, as he is kept the straight man throughout the whole short.
Nearly everything related to Chad VanGaalen, but in particular the video for his song "Molten Light", which he animated himself. The acid trip animation is not helped by the fact that the song is extremely disturbing by itself, on both a lyrical and aural level.
Destino is what happens when Disney lets Salvador Dali do a cartoon. No, that is not a joke, Disney did have Dalí work on a short film back in the 1940s, but understandably never finished it. It was revived some fifty years later and unleashed in 2003 in all its surreal glory.
Butthole Surfers' "Who Was In My Room Last Night" mixes deranged animation with live action in order to represent the main character's drug trip. No one really seems to know who animated these segments, but reportedly Rob Zombie was involved, and some of it does look like his drawing style.
The music video for DYE's "Fantasy" (NSFW) starts getting deranged about halfway through, in a way that it's also terrifying.
During most of the nineties and some of the early two thousands, there was an Argentine tv show shown and Sundays that was called Caloi en su tinta. In it, the titular Caloi, a recognized comic artist and writer for the country who sadly passed away in 2012, presented this kind of animation from all over the world. Most of the kids from that time would watch it and love it, even if it was scary sometimes, and Caloi was Savvy enough to walk right in front of the screen and cover it when something like a sex scene appeared. This was the opening to give you an idea of the show, and there are some shorts in Youtube as well.
The Rockin' with Rory segment of The Great Space Coaster television show had an animated music video of obscure origin that was Science Fiction themed and unlike any other animation featured on the show, it had no humorous elements and it was highly detailed and realistic, not cartoony. It was set to a somewhat uncharacteristically somber song by the show's band about dreamscapes (not what the band usually sings about). It featured a giant spaceship with a lone robot occupant visitng a stormy oceanic planet. The planet had an ruined Atlantis-type island with creepy Romanesque statues and a musical orchestra of faceless robots playing classical instruments. The robot orchestra is beamed aboard the giant spaceship for whatever reason. Like most of the animated shorts appearing on this shoestring budget childrens' show, it couldn't have been made for the show. It was probably made for something else even more obscure (possibly some project that ended up in Development Hell) but got bought by the show's producers as cheap filler. As far as what the story in the animated video was supposed to be is anybody's guess.
Invader Zim. Everything is dark, full of sharp angles, dirty and neglected. The huge metropolis where the show takes place looks as uncaring and uncared for as the people that inhabit it. Some buildings look tall enough to look almost impossible. The characters, besides being darkly colored and being drawn with inhumanly sharp lines, are also disproportionate, with huge heads, triangle-shaped bodies and noodle-like limbs.
Many silent-era and pre-Code cartoons from The Golden Age of Animation lived and breathed this trope, including the original Felix the Cat. Early Betty Boop like Bimbo's Initiation, especially had a tendency to dispense with any semblance of reality just for the sake of a laugh. Or, sometimes, for the hell of it, as when a squadron of fighter planes turns into a flock of birds and back again.
The original Popeye animated series get progressively more bizarre in their gags the further you go back and realize Looney Tunes style, Cartoon Physics and other notions of what is real hadn't been standardized yet in early Western animation.
Superjail!! — and its short-lived partner in crime, Robotomy.
To a lesser extent, fellow Adult Swim alumnus Drinky Crow, and keep in mind that this is AFTER the executive meddling. Read the Maakies comic strip for the full eyeball salvo.
Some viewers of the claymation cartoon Gumby have assumed that its myriad surreal imagery was influenced by drug use. However, Gumby's creator Art Clokey claims that drugs were not an influence: "The strongest thing I've ever taken was coffee or orange juice." (The documentary Gumby Dharma reveals that Clokey did briefly experiment with LSD and other drugs in the late 60s, but this was after he made the classic Gumby shorts, and he had sworn off drugs by the time he returned to filmmaking.)
This. As the note beside the previous upload of this video said, "This is either the intro to the '70s era children's PBS program 'Vegetable Soup', or it's the first thing Jerry Falwell saw the moment he arrived in Hell."
The Marvelous Misadventures of Flapjack is pretty much what happens when you try to remake The Ren & Stimpy Show (from its glory days on Nickelodeon, not its crummy autumn year on Spike TV) and get animators to do it that not even John K. would want — not because of his ego, but because he was too afraid of the artwork.
In The Simpsons episode "Krusty Gets Kancelled", when Itchy & Scratchy are bought out by a rival show, Krusty tries showing an incomprehensible Russian cat-and-mouse cartoon called Worker & Parasite, a parody of the Gene Deitch Tom and Jerry cartoons and Eastern European animation, which is known to be very surreal in nature. Naturally, Krusty's reaction is "What the hell was that?!"
The most notable example is the episode "A Glitch is a Glitch," which is animated entirely in CGI and is purposefully made to look very, very buggy, as the entire world is a computer program that's been corrupted, resembling a bad video game beta. It has to be seen to be believed.
Ed, Edd n Eddy's animation style is odd enough to provide a decent example of this trope (even though the show creator, Danny Antonucci did more deranged works than this, as seen with The Brothers Grunt and Lupo the Butcher — both of which were on MTV back in the days when all that was on that channel were music videos, shows about music videos like Headbangers Ball and Yo! MTV Raps, Beavis and Butthead [before and after it got in trouble for encouraging kids to do gross and destructive activities], The Real World, and whatever flavor-of-the-month cartoon they had on as a competitor to Beavis and Buttheadnote Daria doesn't count as "flavor-of-the-month"), espeically with episodes like "1 + 1 = Ed."
Courage the Cowardly Dog features several Art Shifts of varying displays of animation. Also, the art style is a bit unusual considering an injury has the character let out a goofy expression complete with idiotic laugh, which mostly happens to Courage.
Squidbillies. Dan Halen with all his weird schemes and nonsense he inflicts upon Dougal County would count alone but Early Cuyler's life cranks it Up to Eleven. He has a "truck-boat-truck", which is exactly what it sounds like and equipped with massive monster truck tires. Plus there's unrelated craziness like a snake boy, a boy with sticks for arms and legs, and a field full of sheriff clones.
KaBlam! lives and breathes on this trope. Only a few shorts (and by "few", we mean enough to count on one hand) were grounded.
The Mushroom Samba sequences in the "Mayhem Night" episode of Motorcity are some of the trippiest of its kind, and rarely anything seen in a kid's, much less Disney, cartoon.
My Little Pony: Friendship Is Magic is generally tame with its animation, but whenever Discord shows up and creates a World of Chaos, stuff like talking piles of apples, herds of eyeless rabbits with spider-like limbs, and pies appearing from thin air only to fall into the sky becomes commonplace.
Teacher's Pet, which probably has the most deranged animation out of any Disney show ever made.
Katamari Damacy gives you this impression right off the bat. After finishing the intro theme (which suspiciously involves lots of mushrooms), you'll already be wondering what drug the creators were on when they were making it. And it just keeps getting weirder from there. To start with, you play as a guy with a cylinder for a head rolling things up to make stars, and your dad, who is the king of the universe by the way, pukes rainbows that work as a teleporting device. Right.
The intro to The Beatles: Rock Band. It starts off normal, going on a whistle-stop tour through their career. Then it reaches the halfway point and - *BLAM* - the drugs kick in. Duuuude.
This one makes perfect sense though, if you consider that the point in the video where everything gets weird is the point in the band's career when drugs became a serious factor in the creation of new songs. The tune playing for most of that part is I Am The Walrus, for cryin' out loud!
This deliciously surreal Touhoufanvid which retells some of the story events of Silent Sinner In Blue combines semi-serious scenes with heartwarming nostolgia, art that is very on-model to the signature style of series creator ZUN, and many, many bizarre visual gags and memes. Also, Eirin dances!
The flash video for IOSYS's remixed remix of Reisen's leitmotif, It doesn't stop at the affected area, but goes deep inside and Aah Aaahn ~ The Final Udongein, is a completely surreal, semi-nightmarish glimpse into what you might see if she used her madness-inducing Lunatic Eyes on you.
Earnest Evans used multi-layered sprites to try and make the main character's movements more fluid. It...didn't work out.
"Fruit Mystery" loves this trope. You're an either extremely stupid or insane person who runs around feeding different foods to zoo animals until a timer runs out, then you get a giant Mind Screw at the end. It's horribly drawn and designed on purpose. And yes, it's just as funny as it sounds.
This game. Sleep well. Though to be fair, it's pretty creative.
Y'all so Stupid is entirely composed of this trope. This is the first of several. Probably NSFW, possibly seizure- and nightmare-inducing.
Thanks to the Programs "garry's mod" and "Source Filmmaker" people can now make short films staring the various characters from Valve video games. Some of these are VERY deranged indeed.
Ratboy Genius is animated in Blender, with unbelievably ugly models, very poorly. The effect is both trippy and scary.
Human dreams are the Ur Example (whether you dream in live-action or animation). They don't make sense. They're not supposed to make sense. Crucial parts of the brain are deactivated. Things sorta make sense in context while you're dreaming, but are this trope after you wake up (if you dare to remember them).
It's been said that the average dream is 2 or 3 seconds long, but the brain is still trying to bash them into some kind of coherence, which is why weird things happen for no reason at all.
Another theory is that it's all basically noise that your sleeping brain is interpreting as if it were actual input, producing the infinite nonsense usually apparent in dreams.
