The first REM sleep period usually occurs about 70 to 90 minutes after we fall asleep. A complete sleep cycle takes 90 to 110 minutes on average. The first sleep cycles each night contain relatively short REM periods and long periods of deep sleep.
Although most dreams do take place during REM sleep, more recent research has shown that dreams can occur during any of the sleep stages. Tore A. Nielsen, Ph.D., of the Dream and Nightmare Laboratory in Montreal, refers to this as covert REM sleep making an appearance during NREM sleep.
