[[caption-width-right:298:Apparently, you have to become Caligari.]]

A montage that brings you inside the mind of a character going mad.

Music is heard, which may be quiet at first, but steadily increasing in volume and cacophony. Characters from several scenes may be superimposed, with some of them repeating fragments of their lines over and over again, in the manner of a MadnessMantra.

This may be the time when the character goes AxCrazy and murders someone. Alternately, he may be screaming at the top of his voice, trying to drown out the chaos assaulting his imagination.

Compare BlackBugRoom. Compare also ThroughTheEyesOfMadness, which takes a mad character's POV for a sustained amount of time.

!!Examples:

[[foldercontrol]]

[[folder: Anime and Manga ]]

* There's a single-page version of this near the end of the ''Manga/DeathNote'' manga. Followed by an absolutely ''amazing'' [[SlasherSmile psycho grin]].
* In episode 4 of ''Anime/{{FLCL}}'', Naota fears that his father is in a relationship with Haruko. When his father uses Haruko's catchphrase "mouth to mouth", he sees Haruko climbing out of his father's mouth dressed as a mouse and being mauled by a giant cat with large testes, interspersed with random clips of Haruko from earlier episodes, a voiceover of Haruko from the first episode, all over a soundtrack of indistinct whispering and a swelling distorted guitar track, eventually prompting Naota [[spoiler:to beat his father with a baseball bat. Luckily, he's actually a robot]]. Unusually, Naota remains completely still through the entire scene - not even a hint of Ax Crazy (although probably lots of HeroicBSOD).
* There are a whole bunch of these in ''Anime/NeonGenesisEvangelion'', including all of the last two episodes, and the whole Third Impact part of the movie.
* [[TheWoobie Poor, ]][[TheMadHatter poor ]][[MadScientist Stein]], who spends a good deal of ''SoulEater'' trying to fight hallucinations of melting scenery and [[FoeYay a certain seductive witch]]. In the anime, this culminates in a good part of an episode being focused on his hallucinations stumbling through a fog of crazy.

[[folder: Comic Books ]]

* ''ComicBook/{{Grendel}}'': Eppy Thatcher gets these every so often.

[[/folder]]

[[folder: Film ]]

* The Ken Russell film ''Film/AlteredStates'' has an example. Or does William Hurt flying around on a flaming cross wearing a 12-eyed goat's head count?
* Reversed: There's a montage like this in the mind of John Nash, in ''Film/ABeautifulMind'', as he's ''proving'' his madness to himself.
* Used as the climax of the movie version of Music/PinkFloyd's ''Film/TheWall''. The same thing, albeit obviously limited to the trope's audio portion, applies to the album.
* A wordless version of this is the track 'In The House- In a Heartbeat' from the ''Film/TwentyEightDaysLater'' soundtrack. Spooky.
* ''Film/TheCabinetOfDrCaligari'' is the UrExample. "You must become Caligari!"
* ''Film/RequiemForADream'': When Mrs. Goldfarb's abuse of amphetamines catches up with her.
* ''Film/{{Pi}}'', also by Creator/DarrenAronofsky, has several of these, illustrating Max's degenerating mental state.
* All the hallucinations poor Lawrence has in ''Film/TheWolfman2010''.
* The end of ''Film/PansLabyrinth'', if you take the AgentScully approach to the plot and see it as all just a hallucination.
* The last scene of ''Film/TheAviator'', as Howard Hughes, finding himself unable to stop repeating the phrase "the way of the future," looks into a mirror and sees a reflection of the first scene of the movie.
* ''Film/SecretWindow'' has his.

[[/folder]]

[[folder: Live Action TV ]]

* Episode ''The Time Is Now'' of ''Series/{{Millennium}}'' featured a 10 minute variation of this. It pretty much portrayed [[spoiler: Lara Means']] mind shattering in the face of the [[ApocalypseNot Coming Apocalypse]].

[[/folder]]

[[folder: Music ]]

* An audio interpretation of this trope can be heard at the end of the [[{{Queensryche}} Queensr˙che]] album ''OperationMindcrime''.

[[/folder]]

[[folder: Theatre ]]

* The climax of the "Loveland" DreamSequence from the musical ''Theatre/{{Follies}}'': Ben stops singing "Live, Laugh, Love" and goes into a hysterical rant ("I don't love me!"). The orchestra continues playing and the dancers keep dancing... about a dozen musical numbers ''simultaneously''.
* In ''Theatre/TheAddingMachine'', when Zero's boss is telling him that he's been fired after twenty-five years on the job, music starts soft and grows louder and louder as the stage revolves increasingly rapidly. The boss's voice is obliterated under a deafening cacophony of sound effects, and a sudden flash of red ends the scene.

[[/folder]]

[[folder: Webcomics ]]

* ''Webcomic/{{Homestuck}}'': [[http://www.mspaintadventures.com/?s=6&p=002879 subverted with John]], [[http://www.mspaintadventures.com/?s=6&p=006273 played straight with Karkat]].

[[/folder]]

[[folder: Web Original ]]

* When ''ToddInTheShadows'' sees the [[LadyGaga Bad Romance]] video for the first time - bits and pieces flash on the screen until he begins screaming that she's a demon from hell.

[[/folder]]

[[folder: Western Animation ]]

* An unlikely example from ''SpongebobSquarepants'': The empty white room where Squidward is ''alone.''
