Now narcolepsy is really hard though because they're very tired during the day, they're sleepy during the day and it's managed mostly with medications. So we use medications to help them sleep better at night and to stay away during the day. But there are behavioral things you can do also by changing diet, exercise, having an actual nap schedule.

So you have it, you awaken from it and you can recall, in detail, what just happened, that's a nightmare. So it's very different from a dream where you generally don't wake up from it and you don't have this dysphoric emotion.

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.

There are some people who believe that dreams really are just kind of a throwaway thing. They are just a way of your brain processing what's happening during the day, but there's really no meaning to them; a lot of imagery of just flashes of what happened.

So if somebody has chronic pain, we want to manage the pain, but we still want to treat the insomnia separately. So what we'll tend to do in our sleep lab is we'll do a thorough evaluation and we usually have myself, who is a Psychologist and a Sleep Behavioral Sleep Specialist, I treat the patients first.

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.

So when you're in REM sleep, your brain is very active, our body is quiet, but your brain is really processing a lot of things, a lot of emotions; we dream the most in REM sleep. And then you go back down in the deep stages, and so on and so forth.
