You know, that's interesting about the toilet and dreams, because when my sister and I were young children, my sister had big bed-wetting problems, and I never did.  Of course, I didn't understand why she had the problem.  But now I wonder if the dreams with the toilets were my body sending me a message that I should wake up and go use the bathroom!

Yeah the positive aspects of lucid dreams are certainly alluring, so there's really a battle going on in my head. :)
