Alright, here's one where I felt really powerful:

I was riding on the top of a train, and a girl from school is in front of me. I said something to her, and she got really mad at me, so I jumped off, thinking she was going to attack me. She jumped off too, and we both rolled down a hill. It was in a semi rural town late at night. Running, I go into a building. There's no lights on and nobody in there. Knowing it's a dream, I'm not sure what will be in there, so I don't go any further than the front room. I turn around and there's the girl. I run and shove past her to go outside. Lights come up around me as I go into the drive way, and she's trying to start my truck. She's got friends there who are witches apparently, and they're slowing me down with some magic thing, making me move REALLY slow. To taunt the girl in the truck, I hop on one foot, going even slower. I then hear it start up. I snap my fingers, expecting the car to blow up.Nothing happens. I then imagine a flame in the middle and snap my fingers. The truck shoots up in the air, flames shoot out of the windows, and the girl and her friends are all killed. I walk down the street in the cool night air as the dream ends.

Pretty epic, no?
Here's another, just for the fun of it.

Round two of the last dream. This time, the leaders (who for some reason, I think to be Skynet from the Terminator series ) decide it's not a game anymore. We must be eliminated. We take off running, and a white fighter plane comes after us. We hear a loudspeaker announcing that they are going to be launching a bomb, and we jump off into some forest on the side to hide. Some of us are still carrying our airsoft guns from last game because we were so shocked. My friend Zach has a 30 pound SAW (Squad Automatic Weapon). He jumps down into the trench with me. Suddenly, the whole thing doesn't seem right to me. I realize I'm dreaming. At first I dismiss it. I recognize that I'm dreaming, but it doesn't mean anything to me. Then I realize I can use it. My friend Dan is there. I say "I'm dreaming. I can get us out of this". I turn to Dan and I tell him "Hey, you're having a dream too." He looks at me and says "you told me that three hours ago. I was lucid, but thunder kept waking me up." I look to a tree on my left, and find a Barret sniper rifle. I lift it up and fit it to my shoulder, and then I realize there's no magazine in it. I feel something very heavy in my pocket, and pull out the clip. The bullets didn't look as big as they should have been, but oh well. I raise it to my shoulder and look through the scope. It's cool, because I have to find my target myself, but I know I can always make one appear if I need to. I see a white van driving around in circles and realize it's looking for us, so it can tell the drone where to go. I shoot it twice in the side, but nothing happens. I can't find it, so I zoom out the scope. Now I see it. Sweeping the scope to the left, it moves just faster than the truck. I pull the trigger and the bullet hits one of the tires. It spins out and crashes into a tree before rolling down a very long hill. Satisfied, I drop it and the dream ends
You better feel special that I used my 900th post on you.
