Answer 1

Before my roomate was woken up by my laughter, he was in the third NON-REM stage of sleep.

Stage 3 is deep sleep, and during this stage, a person may experience sleeptalking, sleepwalking, bedwetting, nightmares, etc. The term we use for these behaviors is parasomnias and usually happen between NON-REM and REM sleep.
