LOL..There are many reasons for this I suppose. I always have to go when I wake up, but I
have not always been dreaming before it happened. Dreams are interesting.
There is a book called, "The Dictionary of dreams and their meanings," "Interpretation and
insights into therapeutic nature of our dreams."Its written by Richard craze.. You may
really enjoy the reading and learn a lot about it. It is written in easy to understand
terms and it is fascinating really!
