At this time, people will be in a dream state or in dreams and may appear body movements.

Non-REM sleep is the exact opposite of REM sleep when the body is completely in deep sleep. With non-REM sleep, blood pressure, heart rate, breathing rate, and metabolic rate all drop. Meanwhile, the brain waves become very strong and low in frequency. At this point, body movements will not be possible. However, you can still have dreams while in non-REM sleep
