As an individual continues through stage 1 sleep, there is an increase in theta wave activity. Each subsequent return to REM grows longer. This phenomenon has been called " sleep inertia. A full night of sleep—typically in the range of seven to nine hours—is necessary to achieve all the restorative benefits of REM sleep.
For example, alcohol before sleep tends to suppress REM sleep early in the night. Most dreaming occurs during REM sleep. The rapid eye movements that occur can be seen as sharp, rapid movements.

What the brain waves of each stage of sleep looks like. Brain imaging studies on people going through REM sleep reveal that there is increased activity in both the visual association area which is involved in recognition of visual images and limbic system which plays a major role in generation of emotions and decreased activity in the prefrontal cortex which is concerned with reasoning.
Awakenings or arousals are rare and often it is difficult to awaken someone in Stage 3 sleep. On average, you will spend about two hours per night dreaming. Rem And Nrem Sleep Mentation.
