The eyes jerk around rapidly, and lastly, limb muscles are temporarily paralyzed. The brain waves increase to levels experienced when a person is awake (“Stages” - Sleepdex).
The research in this paper contains: who Sigmund Freud is, what he did and the different stages of sleep. These stages consist of stage one, two, three, four and lastly the REM stage. A complete sleep cycle takes 90 to 110 minutes to complete. Now knowing what happens when you sleep, does it put you at
