What is non-rapid eye movement sleep disorder?
Non-rapid eye movement (NREM) sleep arousal disorders involve repeated episodes of incomplete awakening from sleep, most commonly sleepwalking or night terrors (also known as sleep terrors), but occasionally more complex behaviors.
What’s the difference between NREM and REM sleep?
NREM or non-rapid eye movement is a group of sleeping cycles which can be broken down from stage 1-3. REM is not included here. In NREM, muscles are paralyzed due to the deep sleep unlike in the REM cycle. Dreaming also does not occur in NREM unlike in the REM cycle.

How long is non-REM sleep?
NREM sleep constitutes about 75 to 80 percent of total time spent in sleep, and REM sleep constitutes the remaining 20 to 25 percent. The average length of the first NREM-REM sleep cycle is 70 to 100 minutes. The second, and later, cycles are longer lasting—approximately 90 to 120 minutes (Carskadon and Dement, 2005).
What are the three stages of non-REM sleep?
