REM sleep:

Rapid eye movement during sleep:

Rapid eye movement is basically a mentally active period during which dreaming occurs, provided a biological explanation for this phenomenon. On this basis itself it is seen that there is a development in treatments for major sleep disorders such as insomnia and sleep apnea. REM sleep is defined as is an active period of sleep marked in humans by intense activity in the brain and rapid bursts of eye movements. As the stages of sleep advance and change it is seen that that blood pressure, heart rate, and other body functions in humans rise and fall in a pattern during sleep. Scientists have observed that these movements these movements were recorded by placing electrodes behind the eyes. There is a change in the muscle activity as rapidly changing brain waves that alternated with periods of deep, quiet, sleep marked by large, slow brain waves.

How does it occur?

As sleep is a complex activity, fundamentally different from waking, but just as active and hence it provides a biological marker for dreaming so that immediate dream reports could be collected. All these factors provoked the psychologists and scientists to examine the physiology of sleep. At the time of experiment some people were woken up deliberately during REM sleep and asked them about their dreams, they found that almost all who awakened during REM sleep could remember their dreams. Another striking factor was noted that people who claim they do not dream really do not remember their dreams the next morning.
