Dream Buzzkilling

I wake up a lot.  I rarely sleep more than two hours without waking up — usually it’s about an hour and ten minutes.  I think it might have something to do with figuring out that what’s going on couldn’t possibly be real.  I really need to stop trying to find addresses in dreams, or trying to return to the place I just left (it’s never the same place on the other side of the door).  Looking back at someone seems to always find they’ve changed into someone else.
