REMREM means ‘rapid eye movement’. This is because the eyes move very quickly.The first REM phase starts about 70 to 90 minutes after a person falls asleep.People have between three and five REM phases a night. They are not awake but the brain is awake and active.People dream during REM sleep but the body can not move.That stops people ‘acting’ their dreams.
