I usually think about what I am going to do the next day when I'm laying in bed about to fall asleep. Also i think about the plans I made for the next day. Or I think about what I did that day before I go to sleep. A dream that I have often is about me dtiving my dream car which is a 2002 SS Camaro 6 speed. And it is the best dream ever, because it would be sick if I do ever get that car. The worst nightmare I have usually have is about me running, and I tripped and fell off of a huge cliff. The cliff was endless it seemed like, and right before I hit the ground I woke up and I was freaked out and sweating. And in my dream it seemed like I feel for ten minutes. When I am day dreaming it is usally about skateboarding, or riding dirt bikes. It turns out that my dream about me falling off of a cliff was dealing with that I subconcusly thought that I have failed at something.
