It takes about fifteen minutes to fall asleep. Then your sleep pass by cycles of 90 minutes and each cycle have within 2 phases. Phase 1: Your brain waves down its frequency and enter into a deep sleep, also known as non-REM sleep. Phase 2: The frequency increases and begins the REM sleep. That's when you start to dream.
