A character is bored or uninterested in learning something. Or he/she is just completely uninterested in a certain topic and doesn't understand why other people value it so much. Or he/she is just a mean person who doesn't understand why his/her behaviour is wrong. In all cases, he/she doesn't care about the topic and even pokes fun at other characters for taking it so seriously.

Then he or she goes to sleep. Before he/she falls into unconsciousness, they might even say: "I wish that certain person/event/product didn't exist." As he/she starts dreaming, [[TalkingInYourDreams some legendary character arrives and provides the person with a lot of background information about the topic]]. Sometimes the dreaming ignoramus has put in the action him/herself. Or he/she sees a world where the [[BeCarefulWhatYouWishFor people or things he wished didn't exist now indeed don't exist, with catastrophic consequences]]. In any case, he or she finally gains knowledge, respect and enthusiasm for a topic he/she originally knew nothing about.

When the character eventually awakes, if they were supposed to be the antagonist, he/she makes a HeelFaceTurn. He/she is glad that it was AllJustADream and finally realizes the importance of learning math, respect for your country, [[ThickerThanWater respect for your ancestors]], respect for people he/she formerly threatened or hurt, why a certain product is necessary,... and so on. In most cases, he/she even becomes a vocal supporter of the cause.

This plot device (which some audiences may consider corny if it's not done well) was very popular in old educational films and tv series.

* At one point in ''Anime/LegendOfGalacticHeroes'', Reinhard von Lohengramm of the Galactic Empire contemplates grinding his rival and WorthyOpponent Yang Wen-li's battlefleet down via attrition with his overwhelming strength, but a visitation by [[spoiler:his dead friend Sigfried Kircheis]] convinces him to offer a cease-fire instead.


[[folder: Film ]]

* Happens in the 1943 Film/CabinInTheSky, where a man who gambles too much has a DreamWithinADream where some angels and devils try to get his soul. As he awakes in real life he throws the dice away and swears to repent and devote his life to going to Church more often.
* Wayne's plan for Waynestock in ''Film/WaynesWorld2'' is the direct result of a dream with Jim Morrison telling him to set up a huge show in Aurora. Others he recruits also mention having the Jim Morrison dream later on. WHOOOOOOOOOOAAAAAAAAAAAAA!
* This is the concept of the movie ''Film/{{Inception}}'', including the title, which refers to the act of specifically engineering an Opinion-Changing Dream for another person without them realizing it.
* Also the entire point of the film ''Film/{{North}}''. The titular character is annoyed with his parents until he wakes up from his dream and accepts them for who they are.
* This is one possible explanation for Coily in ''Film/ACaseOfSpringFever''.
* ''Film/TheFamilyMan'': A mysterious man named Cash shows Jack an alternate life where he chose to start a family with his college girlfriend Kate rather than become a Wall Street executive who doesn't yet realize he's LonelyAtTheTop. Cash describes this as a "glimpse" and thus only temporary, but Jack does wake up in the same place and time before the glimpse began, his downtown bachelor's apartment. The experience leads him to track down Kate and reconnect with her after by giving a heartfelt description of the life he saw they had together.


[[folder: Literature ]]

* ''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.
* One ''Literature/BerenstainBears'' book centered on [[GreenAesop environmentalism]] had Papa Bear go through one after he decided he didn't need to recycle or plant trees to replace the ones he cut down.
* The children's book ''Literature/JustADream'', a classic [[GreenAesop Green Aesop]], is entirely based on this idea. As in the above example, the main character is uninterested in environmentalism until he has a series of dreams showing what the world might be like if no one took care of the earth.
* 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.


[[folder: Live Action TV ]]

* ''Series/HighwayToHeaven'': Two episodes from the late winter of 1986:
** "Heaven On Earth," where Mark vents his frustration over how unfair it was that a cute 5-year-old girl he had just met was killed in a car accident caused by a drunk driver, and a number of other more mundane situations, and wishes he could be God for a day to "make things right" in his view. When Mark goes to rescue a teen-aged girl who was trapped in a [[HouseFire burning house]], he is overcome by smoke and falls unconscious. Instead of burning to death, however, Mark is allowed to have a dream where his desire to play God is played out, only with results that he didn't foresee (such as the aforementioned teen-aged girl, who was a hard-working young girl learning about responsibility becoming an AlphaBitch that would make Nellie Oleson look like nothing) ... and the little girl that died in the car accident is still dead. Mark soon realizes that God has a reason for things happening the way they are and that some things, as bad or unpleasant as they are, are out of his (Mark's) control. Mark soon realizes that his vision of "Heaven on Earth" is best left to God.
** "The Torch," where a Holocaust survivor, Everett Soloman, who is on the speaking circuit to talk about his experiences and to warn students against complacency, comes into conflict with a neo-Nazi group who try to intimidate him by killing his son. Soloman has a bad heart and needs a transplant and there seems to be no hope ... until the man that killed his son is accidentally killed himself after a machine gun in his basement accidentally discharges. The upshot is that the killer's heart is a perfect biological match for Soloman, and the transplant is a success ... until Soloman learns the identity of his donor. Soloman has a heart attack and nearly dies, but while he is being revived, the trope kicks into play: He has a dream where he is visited by his mother and father (who both died in the Nazi war camp, in a method that would be indescribable anywhere) and his son, who urge him to continue to speak about the Holocaust, how it was allowed to happen and what can be done to never let it happen again. Soloman soon recovers and, with renewed purpose, is back on the speaking circuit.

By the end of the episode he's much more interested in Shakespeare's plays.
* 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.

* An episode of ''Series/NowAndAgain'' has the main character Michael Wiseman complaining about a need for reading material which is dismissed as unimportant by Dr. Morris, only for him to then dream that the nanotech used to maintain the artificial body Michael's brain is in that the doctor created have run amock and begun eating all the printing ink off of all paper in the world including money. After witnessing the apocalyptic loss of all printed works from the world when he wakes and realizes it was a dream he changes his mind and begins making reading material available to Michael.
* An episode of ''Series/SmartGuy'' uses this, with a twist: Yvette has been struggling with her college applications, afraid to apply to her dream university Brown for fear of rejection and instead "playing it safe" with a less renowned state college. Then she has a recurring dream in which she marries Marcus's dimwitted friend Moe Tibbs, whom she isn't attracted to at all such that the initial dream is treated as a CatapultNightmare. After several nights of trying to find out why she's having these dreams, she eventually plays along and joins Dream!Moe on their "honeymoon" at a cheap motel room. When Yvette questions Dream!Moe on what their future will be like, Dream!Moe responds that he's content to just coast on by with minimum wage job and his ZanySchemeOfTheWeek, putting in the bare minimum amount of effort. Yvette, horrified that ''this'' is what her future will be like, realizes that because she settled on her choice of college, she settled on love and on life as well, only "choosing" Dream!Moe because he was safe and familiar. Dream!Moe then inspires her to apply to Brown like she had wanted, and when she wakes up she immediately rushes to fill out her application.

* 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.


[[folder: Theatre ]]

* In ''Theatre/GuysAndDolls'', during the scene when the gamblers are attending the revival at the Save-A-Soul mission because Sky won a bet, Nicely-Nicely Johnson recounts a dream he had that turned him from his wild gambling ways, "Sit Down, You're Rocking the Boat". (Clip from the 2011 Broadway revival is [[https://www.youtube.com/watch?feature=player_embedded&v=bnzSSPP4mGE#t=0 here]]; the film version (performed by Stubby Kaye) is [[https://www.youtube.com/watch?v=lCfGjUfXUIE here]].) The trope is subverted, in that Nicely didn't change his ways and may not (probably didn't, in fact) even have such a dream at all.
* In ''Theatre/FiddlerOnTheRoof'', after Tevye decides to cancel the ArrangedMarriage between his daughter Tzeitel and the elderly drunk Lazar Wolfe, he realizes that his wife will not accept the decision without some spiritual reason underlying it, so he pretends to have a dream in which he is confronted by the vengeful ghost of Lazar's late wife, who threatens to haunt and kill Tzeitel if the marriage goes forward.

** "WesternAnimation/TheBigSnooze" has Elmer Fudd [[NoFourthWall tearing up his Warner Brothers contract]] after being bested by WesternAnimation/BugsBunny one time too many. Bugs invades his dreams and induces [[DerangedAnimation a truly bizarre nightmare]] as only Creator/BobClampett can produce, prompting Elmer to get back to work.
* The ''WesternAnimation/TomAndJerry'' cartoon "Heavenly Puss" shows Tom dying and going to Heaven. There he is told that he should go to Hell, but if he can make Jerry sign a contract of forgiveness he may enter Heaven. Tom goes through great lengths to do so, but in the end he fails and is cooked in Hell. Then it turns out it was AllJustADream and he hugs Jerry to become friends again.
* In ''WesternAnimation/SouthPark'':
** Mocked in "I'm A Little Bit Country" where Cartman acts as if he doesn't care about American history so that he can induce an opinion changing dream. He elaborately stages incidents that would render him unconscious so that he can have the educational dream and thereby avoid the bother of actually studying. After many amusing failed attempts, he succeeds.
** 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.
** Happens a second time with "Jewpacabra", where Cartman's tranquilizer-fueled dream of the Book of Exodus has such an effect that he '''converts to Judaism'''.

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.
* ''WesternAnimation/{{Arthur}}'' featured this plot with Binky. Binky regularly does good deeds because he knows they're the right thing to do. He told a teacher to stop his friend from doing a dangerous stunt, [[BeingGoodSucks causing his friend to get detention and hate him, and doing so made him miss the wrestling special he wanted to watch]]. He resolved to stop doing good deeds until he had a dream where his favorite wrestler told Binky that doing good deeds was the best thing he ever did and the world would be a much worse place if he didn't do them.
* ''WesternAnimation/TheSimpsons'': In ''"Bart the Lover"'' Bart's class watches a 1950s educational film which has a young man foolishly wish that zinc didn't exist (?!), which proceeded to ruin his life because he couldn't (a) drive his zinc-less car to pick up his girlfriend for a date; (b) call his girlfriend to postpone their date with his zinc-less telephone; and (c) shoot himself in despair (as even the hammer in the gun was made of zinc). The young man is quick to regret his desire for a world without zinc ("Zinc! Come back!"); fortunately, it turns out to be AllJustADream. Then he happily states to be glad to live in a world of zinc.
* An episode of ''WesternAnimation/SagwaTheChineseSiameseCat'' centers around a conflict between Dongwa and his father, Baba. They both come from a family of cats that have primarily been scribes, but Dongwa is more interested in practicing kung fu than in doing his "scrolls" homework. When Dongwa coaxes his sister Sagwa into doing his work for him, Baba finds out and scolds them. But when Baba goes to bed, he has a nightmare that flashes back to ''his'' younger days, when he wanted to play outside but his grandfather insisted on him doing his scrolls. The next morning, partially due to this, Baba and Dongwa are able to reach a compromise: writing is still an important tradition, but Baba will give Dongwa less scrolls to do so Dongwa doesn't have to think of it as work, and Dongwa can use the additional spare time to practice kung fu.
* In the ''WesternAnimation/CatDog'' episode "It's A Wonderful Half Life", Cat and Dog go to bed angry after an argument, each wishing he wasn't stuck to his brother so he could live his own life.

Sarah Lynn was [[ThePerilsofBeingTheBest having some problems with stardom]] and [[ThePowerOfFriendship wanted to rely in a true friend]]...until she realized he had come for the guest spot, [[NiceJobBreakingItHero leading her to drugs and booze to cope and the state she was at the beginning of the series]]. And [[AesopAmnesia he's repeating the same mistake again]].
