If there's a lot of fear that's going on, if there's a lot of anxiety, it's manifesting itself in your nocturnal world so that analyzing it can help open up basically thoughts about what you need to do during the day. So a lot of people who subscribe to the psychoanalysis, the Jungian thought will really focus a lot on dreams, the meaning, and how it can be used to help you during the day.

So when it comes to circadian rhythms, it's a clock that's basically programmed in our body. So if you think back to times when people lived on farms and we didn't have electricity.

It's uncommon, but there are some people who just have a delayed circadian rhythm and they just - they sleep better during the day then they do at night. So they've - a lot of those people with delayed sleep phase disorder they start to work in bars, they work some of the late night shifts, they sort of adjust to doing it more and more as time goes on.

So the deeper stages of sleep are really those times of quiescence, you're really restoring your body and we have a few different stages of sleep.

We'll work on relaxation strategies and also changing the times you go to bed will actually make them sleep a little bit less for a few nights so their body's natural sleep drive starts to kick in. That is very effective in about 60% to 70% of patients who do it, four to eight sessions, not even every week; it works for 60% to 70% of patients.

We're not really sure why it [broken circadian rhythm] continues, but when they become adults, we usually have to treat it because many people need to get up early to go to work and they can't be sleeping until 11:00 or 12:00. So we use treatments like bright light therapy, melatonin, things like that that are very effective.

There are some patients who just have insomnia and they've had it since they were a kid and we don't quite know why. So when we look at the cause, we definitely want to treat whatever else is going on, but insomnia often because it becomes its own diagnosis and that requires its own treatment.
