REM (Rapid Eye Movement) sleep is the stage of sleep where most dreaming occurs. By waking Margie after five minutes of REM sleep and asking her what she's dreaming, the roommate can prove that Margie does in fact dream. Feeding Margie lots of rich food may cause her to have more vivid dreams, but it doesn't necessarily prove that she didn't dream before. Making an all-night audio recording of the sounds Margie makes while sleeping is not a reliable indicator of whether or not she is dreaming. Waking Margie after she has been asleep for about 5 minutes and asking her what she's dreaming may not be enough time for her to enter REM sleep and start dreaming.
