Document Summary
Narcolepsy is a disease marked by sudden and irresistible onsets of sleep during normal waking periods. People suffering from narcolepsy go directly from wakefulness into rem sleep. (falling asleep while driving) Sleep apnea involves frequent, reflexive gasping for air that awakens a person and disrupts sleep. Apnea occurs when a person literally stops breathing for a minimum of 10 seconds. Nightmares are anxiety-arousing dreams that lead to awakening, usually from rem sleep. Person who awakens from nightmare recalls a vivid dream and may have difficulty getting back to sleep. Night terrors (also called sleep terrors) are abrupt awakenings from non-rem sleep accompanied by intense autonomic arousal and feelings of panic. Can produce remarkable accelerations of heart, usually occurring in stage 4 sleep early in the night. Panic normally fades quickly, and a return to sleep is fairly easy. Somnambulism or sleepwalking occurs when a person arises and wanders about while remaining asleep.
