I guess I kinda had control last night.
I had a dream last night where a bunch of medieval knights were attacking me, when I suddenly realized that I was dreaming. I decided it was probably a good idea to get myself out of the predicament I was in first, so I held out a hand of mine, pointed it at one of the knights, and said "Stop!" He froze. I then went to some kind of parking lot, and a bunch of flies started buzzing around me. I said "Flies, die!" a couple of times, and they all died.
I reached a street, and tried to make lightning shoot out of my fingers, Sith style. I pointed my hand to the sky and screamed "Lightning," but instead of it coming out of my fingers, I made there be lightning strikes in the sky. I repeated myself, hoping for a different result, but I just made more lightning bolts.
Then I looked back up to the sky, and noticed a bomb was about to hit the city I was in, which pretty much scared me right back out of lucidity. >_<
