It would be cool to be able and document your dreams. I forget a lot of what I am dreaming about. I think the key would be to put a notebook next to your bed. Everytime you wake up in the night..you write what just went on..

When I was a kid I used to dream that I had to pee real bad..So, in my dream I would go behind a tree and go to the bathroom. Then I would wake up mid stream and be peeing in my bed. Embarassing..It didn't happen that often.
