Without this stage, one can have failed responses, this also includes noises failing to generate a response within the body. REM sleep is s A deep sleep during which the brain is very active, rapid eye motion occurs and dreaming begins. In this cycle Beta waves dominate. During the moments when brain waves spike, REM sleep is occurring. REM sleep happens about five to seven times during a normal sleep.
