I was thinking of some things I think I thought of something pretty decent. I thought you could right "I am ________" on your hand. Then when you look down on it then you would have to think "am I awake or dreaming?" then mentally fill in the blank. Then in a dream you would see and be like "the guy over there flying isn't very realistic... Maybe I'm dreaming!?!?!?". Well give me your thoughts on it !!!
