Conscienceness and the two track mind

In this chapter i really enjoyed learning about the 5 sleep cycles we go through in 90 minutes. I was able to visualize all the stages. The ones where we aren't so asleep to the heavy sleep stage. It was also neat learning that the body had sleep cycles according to light and we regularily mess that up. I know this applies to me a lot because some nights i will turn in early to get good rest for a swim meet and other nights i'm up til the late late hours trying to study for something. After reading the effects that had on the body i know i want to try and find a regular sleep cycle from now on reguardless of what i have to get done.
It really surprised me, even though it may not be quite appropriate, the dreams we have. I was surprised to see that we do not have as many sexual dreams, especially guys. That a guys so called "morning erection" does not come from the type of dream he is having, but from his last REM period of sleep. That really struck me as surprising!
In this chapter it is obvious to say, because i'm sure we are all talking from personal experience, that a good nights sleep does the body wonders. I agree with that much because i know when my body doesn't get the sleep it needs, it starts to shut down and i can not perform the way i can when i have a good nights sleep. However, i disagree with Freud when he talks about the importance of dreams and how they are just revealing our deepest desires and such. If that were so, then Freud is saying my deepest desires at night is to be chased down by a crazy person with the potential of being killed? I think not. And i have had the dream where i am being chased, it is not pleasant and i know for a fact it is not at all what i desire. So where it may be true in some cases he can not claim that it is true for all. Yes, we do need a good nights sleep to perform well, but no, dreams do not express what we deeply desire.
