I think I might have a form of Alzheimer's disease.  Sometimes I wake up in the middle of my awakened slumber and I look around and think to myself, where have I been and how the hell did I get here.  I woke up again today.  It was sad to realize that I have made it so far asleep, what have I missed.  Where would I be now if I hadn't allowed myself to doze off, disappear and give up control.
