** Similarly, in "Trans-Fascism", Hank drives a lunch truck serving then-illegal trans-fat foods. At first he sees himself as a patriot for disobeying an unjust law. A dream featuring George Washington, Abraham Lincoln, and Tom Landry (on Landry's B-17 during World War II) in which they express their disapproval of Hank's actions gives Hank the strength to tell Buck that he wants out.

* In the ''Literature/VitaNuova'', the course of the [[Creator/DanteAlighieri Dante]]'s life is changed when a dream convinces him to give up loving anyone but his deceased OneTrueLove. The dream is probably the least spectacular in the ''Vita Nuova'', since it avoids any cannibalized hearts or crying stars in favor of a lone vision of the WorldsMostBeautifulWoman at the moment Dante saw her and experienced LoveAtFirstSight.

* In the Pluto cartoon, "WesternAnimation/PlutosJudgementDay", WesternAnimation/MickeyMouse punishes [[WesternAnimation/PlutoThePup Pluto]] for chasing a little kitten. Pluto then goes to sleep and has a nightmare where he is sent to Hell and tortured by several cats. When he awakes he changes his ways and acts gentle towards his feline friends.

* ''Literature/AChristmasCarol'': Ebenezer Scrooge hates Christmas and helping the needy. But after a long dream where he is visited by his late partner Jacob Marley's ghost and then three more ghosts he changes his character completely and becomes a good person.

* In one of the earlier ''ComicBook/{{Batman}}'' stories, ComicBook/{{Robin}} (at that time Dick Grayson), was getting so disobedient with Batman that the latter scolded him that his son would end up disobedient like him. Robin ended up having a dream of getting married, having a son, inheriting the Batman costume while his son inherited his Robin costume, but the son was also disobedient like him, but this time with fatal results of trapping him ''and'' his son in a missile heading towards explosion, death was inescapable. When Robin actually woke up, he became more obedient with Batman's instructions. [[spoiler:In hindsight, it became more tragic that [[ComicBook/ADeathInTheFamily disobedience was what caused the second Robin to die horribly]], he did not receive similar opinion-changing dream.]]

* In one of the ''Literature/ArabianNights'' stories, a princess hates men because she dreamt about a male bird who left his mate to a birdcatcher, to save himself, after she had stayed behind to rescue him. A strange plot device, considering that the princess lives in a world where her father will ''execute'' her for losing her virginity ... it's not as if she needs a dream to have a low opinion of men. But, of course, her hate of men is easily remedied by telling her the truth about the end of that story; the hero (who, for some reason, had the ''same'' dream) tells her that the male bird was killed by a falcon before he could return.

* In the ''{{Series/Dinosaurs}}'' episode "And the Winner Is...", B.P. Richfield runs for Chief Elder and has Earl Sinclair run against him so Richfield would win. At first Earl is willing to lose, until he has a dream of [[CrapsackWorld a world run by Richfield]], where Earl's family is poor and minimum wage is lowered to a few cents. This dream inspires Earl to try harder to win. Later, when his popularity goes up but the family remarks that Earl might not be smart enough to make a good chief elder, Earl [[GenreSavvy refuses to sleep]] knowing he'll have a dream convincing him that he'll make a terrible chief elder. And he is right.

* In ''Literature/TheBible'' (Acts 10:9-23), Peter falls into a trance and sees many animals which were forbidden (unclean) for a Jewish person to eat. He is commanded by God to "kill and eat," but replies that he had never broken Jewish dietary laws before. God replies, "What God hath cleansed, that call not thou unclean." Peter learns from this to accept the Gentiles (non-Jewish people) as converts to Christianity and to no longer treat them as outsiders to the faith.
** When Joseph discovers that Mary is pregnant before they are even married, he plans to quietly break things off with her, [[note]] During this period in time, a woman becoming pregnant out of wedlock could result in her getting executed if he willed it, so this is considered a merciful act.[[/note]] but then an angel comes to him in a dream, telling him to go ahead and marry her anyway, saying she is pregnant with the Son of God.

* An odd example from ''WesternAnimation/CaptainPlanet:'' in one episode, Wheeler opines that people shouldn't have more kids than they can afford, and the other Planeteers yell at him for being insensitive. Then he goes to sleep and dreams that he and Linka are married with a lot of kids. He wakes up with the moral that large families are miserable and bad for the environment, and it's ''framed'' as this trope...except that the writers apparently forgot that ''that was his opinion to begin with.'' It's perhaps the best example of how Wheeler is always treated as wrong, even when espousing the show's own viewpoint.

** Played straight in "Cartoon Wars: Part I". At first, Kyle opposes Cartman's efforts to have the Family Guy episode pulled, but changes his mind after having a dream in which he sees his brother killed in a terrorist attack.

* [[InvokedTrope Invoked]] by ''WesternAnimation/RickAndMorty'' in the episode "Lawnmower Dog", when Rick uses a device to allow them to enter dreams. The original idea was convince Morty's teacher to give him good grades, but things go awry and they end up meeting Scary Terry, a "[[CaptainErsatz legally-safe knockoff]] of [[Franchise/ANightmareOnElmStreet an '80s horror character with miniature swords for fingers instead of knives]]". Scary Terry hunts them relentlessly, until he just gets tired and goes home to sleep. They decide to go into ''his'' dreams, where they help him through a nightmare of his own. Terry wakes up thinking they're cool guys and befriends them. He in turn helps them with their original plan with Morty's teacher. The same trick is used in the B-Plot where Rick has to use the same device to get Snuffles/Snowball/Snuffles to leave Earth with the rest of his super smart dogs and not take over.

* ''[=YugiNoNo=]'' [[https://www.youtube.com/watch?v=FlXR-ZIIPwU has a skit]] in which the Eugene character has a nightmare over being sent to [[FireAndBrimstoneHell Yugioh Hell]] for playing [[TierInducedScrappy Trickstars]]. [[SubvertedTrope He didn't seem to care]].

* At the beginning of ''WesternAnimation/AliceInWonderland'' Alice longs for a world where everything is nonsense. She then dreams of falling into just such a world, and by the end, the sheer insanity of Wonderland makes her tired of nonsense and anxious to go home.
