really? I would assume you enter a dream more quickly when you have less sleep, because your body enters rem more quickly when sleep deprived. I have yet to find a period of time for wbtb in which I don't give in and fall into unconsciousness, but where I can actually get back to sleep. It seems that If I do anything besides look at my ceiling for a few minutes and think about things I am too awake to get back to sleep in this manner, and if I try to do a wild immediately I am simply too tired.
