Also while its very hard to do apparently there is a way to willingly control your dreams. You lie on your back with your eyes closed and don't move. Apparently your body will send signals to see if your awake such as getting itchy, wanting to move, open your eyes, etc. If you don't respond to any of those signals you will feel a wieght on your chest and you will start dreaming. I have tried it a few times and felt my chest get pulled down but I get to freaked out and open my eyes before I start dreaming because I heard if you open your eyes while your dreaming, you go inti sleep paralysis.
Have done this- article said to try turning on lights in your room to see if you're awake, if not you're sleeping. Tricked the hell out of me when the lights didn't turn on the first 5 times I tried.
