Rehab?

Though I had many dreams last night the only one I remember is the last.  I was in a rehab of sorts, and wanting to go home.  Don't know what put me there but I was walking around all the others there were grousing, wanting to leave.  I guess I had to pee because in the dream I was sitting on my bed about to try to go home and looked on the floor and there were two small areas of pee by my bed and I was worried that because of that they wouldn't let me leave.  Then I sat on the floor and began digging in a tan colored purse for my cellphone, which I found, and called my mom and she said she would come and get me.  I hollered to everyone 'my mom's coming to get me!' and everyone was pissed because I could go home and they couldn't.  Mother got there and the staff told her to watch me but let me go home.  We were driving into a town with tall buildings and I noticed down the road (a divided 4 lane), cars were up to their headlights in water.  (we are recovering from a hurricane here), and about that time I finally woke up.
