REM –Rapid Eye Movement sleep is one of the stages of sleep the brain goes through during sleeping. It begins about an hour to one hour thirty minutes when an individual goes to sleep, The brain is active at this period as if the subject fully awake. This explains why the dreams memories is retained when fully awake and the dream is vivid and could be recollected.
Other physiological features associated with this stage are increase in blood pressure, variation in body temperature, and rise in brain oxygen consumption among others.
The full active brain also stimulates the spinal cord for the seizure of motor control to the limbs, These immobilized these body parts with the subject in tentative state of paralysis, hence the REM is is sometimes refers to as paradoxical sleep.
The Non Rapid Eye Movement (NREM) is made up of 3 stages. This sleep stage mark the transition from being awake to deep sleep. It is marked with reduction in brain waves , body temperature,no paralysis of the limbs.
Dreams are rear during NREM stage, and if they occur it is usually early in the morning. This dream is due to activation of the subcortical area of the brain at this period of the day; this includes the olfactory bulb, the hypothalus.amygdala .
