"Hello! My name is Dr. Robert Hernandez. I'm a psychologist in Miami, Florida and I'm president and owner of La Farfalla Retreat House. The cycles of sleep are usually divided into two, you have your non-REM cycles and you have your REM cycles which is the rapid eye movement stage. Again, as you are about to fall asleep, your brain is changing their waves, the frequency that goes through the brain. Most of the studies and the sleep studies that have occurred, the person goes from a sense of arouse state which is your beta then they drop to a more normal calm state which is your alpha waves. Then they get into the theta waves which is a lot more slow moving waves which are indicating that you're relaxing. Then once deep sleep occurs, they hit the delta waves. During REM sleep or rapid eye movement, that's where dreaming occurs and that's where you're going in between your delta and your theta waves. So, there's many different cycles of sleep occurs and most of them are related to brain activity. So, once again, the whole purpose of this is to get a good night sleep."
