Your roommate fell asleep about 25 minutes ago. now, you need to awaken him so that you both can get to a party on time. he is sleeptalking about his girlfriend's cat. when you begin laughing, he wakes up. he was in the stage of sleep.

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.

can you explain it better

no one should discriminated against because he or she is not from a minority group
