In a normal night someone will go through 4 or 5 stages REM sleep. REM periods are shorter early in the night and longer towards early morning. When you are a baby you spend 80% in REM sleep.

Rapid Eye Movement sleep is categorized by rapid movement of the eyes and and rapid low-voltage EEG (brain electricity activity). This stage has the most dreaming. in some dreams or nightmares partial paralysis of your organs may be necessary to protect themselves from self-damage through physically acting out scenes from the sometimes scary dreams that occur during this stage.

Some studies show that if you are interrupted in REM many times, you will make up the lost time with extended REM sleep the next time you fall asleep. Also, if people are sleep-deprived, they enter REM sleep faster. They also spend more time in stages 3 and 4.
