The Dreams while you sleep?

I was just wondering, is it possible for you, when you are sleeping and having a dream, to make that dream into whatever you want? I mean like control the dream? For example, lets say you're dreaming of a football game where you are coaching your favorite team. The QB pes it, its dropped. Could you be able to control your dream and make the next play into a touchdown? (By the way this is just an Example) Another example would be like say you were having the worst day at school. You get home, your tired, stressed, etc. Could you make the phone ring and the person on the other line would be your crush? Would it be possible to control a dream?
