So a lot of people who work rotating shifts and they work at night, their bodies are set to want to be awake during the day and sleep at night. So there are some people who have a lot of trouble adjusting their rhythms and they have trouble working the night shift, they're sleepy, they're drowsy driving home.

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.

When it comes to the reason why we have nightmares, we're still debating that. It's a new area of research, nightmares. And the way I like to think about it is, our brain - we have stress during the day and our brain needs to learn to process this stress.

So it's like your brain has a large filing cabinet and it's opening up each drawer and it's taking in various images and memories from the day, consolidating what it needs to and puts in whatever file. And then if there's something that doesn't fit in any of the files and doesn't really belong, you'll forget about it. So it's a way of really getting a succinct way of storing things in your brain.

The other option we have are medication treatments. So you'll have the treatments such as Ambien, Lunesta, Sonata, and we'll also have Rozerem and for some patients we use Benzodiazopine/Clonazepam. Things like that to help with anxiety.

If you're going somewhere East from here, generally what you want to do is you want to try to have your bed time earlier and earlier so what we'll do is I'll have someone adjust for a week or two by going to be 15 minutes earlier and getting up 15 minutes earlier every night. So that can be a really simple thing.

And you cycle throughout so that you do about five to six cycles throughout the night. And we spend more time in REM later on in the night than we do earlier on.
