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? Or he is just a mean person who doesn't understand why his behaviour is wrong. In all cases he 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 falls into unconsciousness he might even say: "I wish that certain person/event/product didn't exist." As he starts dreaming [[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. Or he sees a world where the [[BeCarefulWhatYouWishFor people or things he wished didn't exist now indeed don't exist, with catastrophical consequences]]. In any case he finally gains knowledge, respect and enthusiasm for a topic he originally knew nothing about.

When the character eventually awakes he makes a HeelFaceTurn. He is glad that it was AllJustADream and finally realizes the importance of learning math, respect for your country, respect for your ancestors, respect for people he formerly threatened or hurt, why a certain product is necessary,... 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.

* In one of the ''Arabian Nights'' 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 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: 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".

Now he is able to recite the entire Pledge from memory.

* 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.

** 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'''.

* ''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]].

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.
