A sequence in which the audience is shown what's going on in someone's imagination instead of things that are actually happening. This may be clear from the beginning, or it may be made to look real at first. Similar to a DreamSequence, but daydreaming or similar instead of actual dreams. Sometimes several characters can have a shared Fantasy Sequence. One can also be used to represent imaginary events being narrated in the story's real world.
* DaydreamSurprise: Where it looks real at first.
** IndulgentFantasySegue: Someone responds with violence, but it turns out they were only imagining it.
* DeepImmersionGaming: Characters are so immersed in a game it's shown as their being inside it.
** RPGEpisode: An episode dedicated to the above.
* FantasyTwist: An unexpectedly mundane or unpleasant one.
* IfIWereARichMan: Fantasizing about being rich.
* ImagineSpot: A brief cut to a situation-relevant Fantasy Sequence and back.
* PowerFantasy: Fantasizing about being powerful and taking revenge.
!!!Sometimes but not always a Fantasy Sequence
* SeparateSceneStorytelling (The separate scene could be in the characters' imagination, or just be shown for the benefit of the audience, and often it's impossible to tell.)
* ImagineSpotting: Where someone else can inexplicably see it.
* MrImagination does these a lot.

* This trope caused the MundaneMadeAwesome in the ''LightNovel/ChuunibyouDemoKoiGaShitai'' anime. Such sequences are out of the fantasies of several [[MsImagination Misses Imaginations]].

* Used frequently in ''ComicBook/TheTaleOfOneBadRat'', especially in the first half. Helen [[DaydreamSurprise imagines herself]] committing suicide several times, or [[ImagineSpot interprets]] other characters and scenes as fable animals or beings from other times.

* ''ComicStrip/CalvinAndHobbes'': [[MrImagination Calvin]] is constantly living in his own world(s), but the use of this trope is actually pretty complicated. In summary, there are a lot of clear-cut fantasy sequences and also a lot of [[MaybeMagicMaybeMundane deliberately ambiguous]] scenes.
** In the clear-cut cases, Calvin imagines riding dinosaurs or being a heroic space pilot (or an endless number of other things), and it can typically be clearly seen that the real world exists around him as he imagines things. Even Hobbes doesn't see these as real. For whatever reason, he also almost never appears in them, absolutely never as himself, whereas other characters may appear as aliens or something else.
** But then there are the events where Hobbes is present as a real if somewhat anthropomorphic tiger, and these also involve fantastic things like time travel or aliens. Hobbes turns into a toy tiger when adults or even other children are present, but by WordOfGod (in the anniversary book) neither the idea that Hobbes is Calvin's imagination or that he's real is more true than the other.
** Sometimes others also can't see things that are real to Calvin and Hobbes, such as Calvin having turned into an owl, but usually these are also left ambiguous, like Calvin's clones of himself just never happening to show themselves to his parents more than one at a time, or the question of how Calvin managed to tie himself to a chair if Hobbes didn't do it.

** In "The Ticket Master", each of Twilight Sparkle's five friends who want her extra ticket to the Grand Galloping Gala imagine, and we are shown, what they would do there. (Make a lot of sales, meet her idols, party like mad, meet the stallion of her dreams, see the exotic plants and animals in the garden.) In "The Best Night Ever", during the song near the beginning, these are recapped with new sequences with the same content, as well as one for Twilight herself.
** In "[=MMMystery=] on the Friendship Express", we're shown various crazy explanations Pinkie Pie imagines about who did the crime and how, each of them parodying some work or genre.
* ''TheNewAdventuresOfWinnieThePooh'': In "Paw and Order", the whole WildWest play the characters are doing turns from a small stage with a few actors into a collective fantasy sequence with several sets, tons of extras who don't have any known actors, and a villain who doesn't either but who still manages to be so willful as to defy the script.
* This is the point of the ''Magnificent Muttley'' shorts on ''WesternAnimation/DastardlyAndMuttleyInTheirFlyingMachines''.
* ''WesternAnimation/Doug'': was loaded with fantasy sequences - usually Doug imagining exaggerated best and worse case scenarios for an action he may take, or a problem he faces.
