ASK A QUESTION
In a classic episode of "Batman: the Animated Series" (called "Perchance to Dream"), Bruce Wayne discovers (spoiler alert) he is in a dream because he in unable to read a newspaper he picks up. At first there are some ordinary words in the headlines, but everything becomes a jumble of gibberish as he attempts to read more closely. He later explains his reasoning by claiming that reading is a function of the right side of the brain, while dreams come from the left.
