Man hole 69 is a fictional story that is very intriguing to me. It talks about a surgery that was performed on three test subjects, that removed the need and the ability to sleep. The subjects were locked in some kind of coma, like a semi death. They were frozen in time. One of the explainations for this incident was that sleep is used as a form of escape from ourselves this got me to thinking about this explainiation and I have expanded it futher. We as people have many different traits, and personailities what if it was almost like there many different people in our heads (in a non-schizophrenic way) and what happens when you put many different people in a small space for an extended period of time? They fight and bicker, we all need time away from people. So sleep is our escape to allow those people room to live in harmony. I promise I don't have multiple personality disorder. At least I think.
