David, Dream Alien Slayer?

Well, I had another dream about aliens showing up and me attacking them. This time, the aliens were in this craft that showed up at the mall. It was silvery and resembled a bumpy silver dish, almost like a silver kickball that someone had tried to squish and was only half-successful at it. I felt like I recognized the ship, like it was something from the new version of The War of the Worlds. It sprouted legs, but I leapt on it and pushed it down. The craft began rolling around like it has wheels under it, and I clung to it (when I tackled it, it shrank to nearly the size of a sea turtle) for dear life. It carried me into a shop in the mall, and I spotted some police officers. One of them was a woman, and I said, "Excuse me, Miss Police Officer Lady, do you have something that can cut glass?" (or something along those lines). She handed me something like a scalpel with a jagged edge when the alien craft rolled close enough for her to reach me. I used it to cut through the craft's silver skin. To my astonishment, the skin was rubbery when I cut it instead of being hard like glass or metal. I glimpsed a fleshly gross alien inside as I tore at the silvery rubber skin of the craft. I don't remember what happened after that.
