Duke Zhou: I dreamed that I peed in the toilet and I peed in the bed.

This is a normal physiological reaction, mainly because you are too tired. When your body reacts, you are still sleeping, so you will find a toilet to pee. You usually wake up when you can't stand it, and some of you will eventually find the toilet in your dreams. Physiologically, you also have a excretory reaction, so you wet the bed. If so, it is recommended to drink less water before going to bed.
