Sleep, and my unconcious

There are two parts of the mind: The conscious, and the unconscious. It's easy to recognize my conscious thoughts. But my unconscious is different. It's hard to understand your really deep desired and such. In the old days, therapists would analyze your unconscious by learning about your dreams. I don't believe that there is any relationship between my desires and my dreams. But some dreams I wake up from and am dissapointed that I have to go through the day. I wish I could sleep all day.
