When tired does Sleep working

I find myself moving around a lot in bed lately and sometimes, when half-awake, realizing that I am physically doing the actions in my dream.  I would dream of myself counting money or putting items into bags only to come out of that dream and notice my body moves naturally to the dream.  I suppose it is because of the constant motion that it becomes routine for the body to move in that particular way out of habit.

There are other times that I hear things I shouldn't be hearing.  I know I am a somewhat schizophrenic and also a mild case of obsessive compulsive personality disorder, but hearing hallucinations seem to occur more often especially after prolong use of a walkie talkie.  I wonder if that is why I hear people chatting in the background when I sleep.  Or maybe there really is someone chatting somewhere.  Hmm.
