HELP! I think I'm having weird issues here?

It's been a while (about few weeks) that most of the times at night I wake up very early (bout 5-6 am) in the mornings that I really gotta go wee. I also usually dream of acually sitting in restroom etc, but I'm worried that once some accident would happen. for a week or two I've been using bladder control pads (tena lady) to make sure I survive the night..

I don't think that I caught a cold, or any disease. I go to toilet before I got sleep. I don't drink in the evenings but still somehow it seems that my bladder has shrunk? Any ideas?
