[[caption-width-right:250:Pay close attention to my preaching 'cause it will change your mind when you wake up!]]

A character is bored or disinterested about learning something. Or he is just completely uninterested in a certain topic and doesn't understand why other people value it so much? Usually it has something to do with history. Or he is just a mean person who doesn't understand why his behaviour is wrong. He is comfortable with his ignorance and just goes off doing banal or evil things. Sometimes he even pokes fun at other characters' seriousness about the topic.

Then he or she goes to sleep and has a dream. Usually [[TalkingInYourDreams some legendary character arrives and provides the person with a lot of background information about the topic]]. Sometimes the dreaming ignoramus is put in the action himself. Now he gains knowledge and enthusiasm about a topic he actually knew nothing about. Or he finally starts to see things from his victims' point of view.

When the character eventually awakes he makes a HeelFaceTurn. He finally realizes the importance of learning math, respect for your country, respect for your ancestors, respect for people he formerly threatened or hurt,... and so on. In most cases he even becomes an vocal supporter of the cause.

This corny plot device was very popular in old educational films and tv series.

When a character actually wishes things to be different, only to find out that life has changed for the worse, you have a BeCarefulWhatYouWishFor. In both cases the character always wakes up, glad that things are just the way they are.

[[folder: Mythology and Religion ]]

* 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."

[[folder: Western Animation ]]

* In the Pluto cartoon, [[PlutosJudgementDay "Pluto's Judgment Day"]], MickeyMouse punishes [[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.
* The PorkyPig cartoon ''OldGlory'' has Porky struggling to get through the Pledge of Allegiance. He falls asleep and is visited by Uncle Sam who tells him about the American War of Independence. Porky learns the value of American freedom and wakes up. Now he is able to recite the entire Pledge from memory.
* Subverted in the WesternAnimation/LooneyTunes short "Pigs Is Pigs", where Piggy is seen eating too much for his own good. When he goes to bed he has a nightmare where a scientist forcefeeds him. Eventually Porky has a BalloonBelly and eats one more piece of food before he explodes. After he wakes up, he still rushes downstairs to continue eating, having learned nothing!
* Another WesternAnimation/LooneyTunes example, "The Big Snooze" has Elmer Fudd [[NoFourthWall tearing up his Warner Brothers contract]] after being bested by BugsBunny one time too many. Bugs invades his dreams and induces [[DerangedAnimation a truly]] [[WhatDoYouMeanItWasntMadeOnDrugs bizarre nightmare]] as only 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.
* In the ''WesternAnimation/KingOfTheHill'' episode "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.
