Parasomnias are Most Sleep Disorders

Any irregular movement during sleep or character of sleep is given the label of parasomnias. There are two different types: NREM and REM parasomnias. NREM stands for non-rapid eye movement and REM stands for rapid eye movement. These stages are the normal stages of sleep. An average person will experience maybe 4 REM cycles during a night's rest. Some parasomnias for NREM include sleepwalking, sleep terrors, teeth grinding, or RLS. REM parasomnias are a lot more dangerous. During REM sleepers with disorders in this stage can experience complete muscle lose or violently twitch and act out dreams.
