Driller Killer Nightmare

Being chased around an old building, a ricketty place with lots of small rooms and cubby holes, many different staircases and everywhere piled high with bric a brac, like an old fashioned ironmongers or a second hand junk furniture store. The crazy man was bent on killing me, I knew it. I kept hiding but he kept discovering me. Finally I found a power drill, charged up and I drove it into his groin as hard as I could, I could not believe what I was doing, but I had no choice and ran for my life in terror. As I ran down the stairs, each step tap tapping faster and faster under my feet I was still convinced even with this terrible and awful injury he was still chasing me and was going to hunt me down.
