This isn't really a lucid dream, just a normal dream.

I was watching TV in the dream with some family that had come over. It was supposed to be like a horror movie. I don't know how, but later, I was actually in the scene. It was kind of like a Holocaust. I had to walk in this dark room along with family, while these lighted words kept coming at my face. If I fell down, I'd be dragged off and killed. I bent over a lot, but I finally made it. It turned out to be a Wal-Mart, and we had to buy stuff to offer to this omnipotent ruler that had started the whole thing. I walked outside, fearing for my life. I asked someone where the houses were, and he said they were up this street. I looked into the night sky and a pentagram formed of stars lit up. We walked up the street, and prostitutes and druggies crowded the sides of the street. Oddly, the exit of the Wal-Mart was an entrance to my elementary-school annex. The whole setting was my elementary school.
