There's a problem for them [teens] when they have to get up and go to school in the morning, they're very sleepy, yet on the weekends, they'll sleep 12 hours, they'll sleep late and then go to bed late and wake up late. And on vacations, it's not a problem.

There are people who have repetitive nightmares. And what happens is their brain is trying to process the stress and help their brain actually deal with what happens if this stress happens again, so their brain's preparing them to deal with it in case the stress happens again, but it's so scary that they awaken from it.

People tend to remember their dreams in the morning a little bit better and if earlier in the night, when you're in a lot of deep sleep, if someone wakes you, or the phone rings or something, you're really confused.

We actually don't know the function of sleep all that well yet, but sleep is a time of quiescence in the brain.

Sleep paralysis is something that is actually very common. Many people have it, I've had it myself. And what happens is, when you're in that REM stage of sleep, your brain is very active. You're dreaming your most during that stage, you're mind, your eyes are moving, there's a lot going on. It's like fireworks going on in your brain.

People went to bed when the sun went down and they woke up when the sun came up. That's what our bodies are naturally programmed to do. However, with all the new stresses in life with electricity, with technology, we tend to override that system and we'll stay up later and we'll get up earlier or later, and we use alarm clocks, we use the light.

So, it's not every patient that I see, but I'd say a good 70% to 80% of the patients when they go to bed it's like a stereo is playing at an 11 or 12 and they can't turn it down, at all. So it makes it very hard for their body to down regulate to be able to go to bed at night.
