I was with my family. My room was different, the baseboards were lifted up on one wall, and I could see into another room because of this. The other room had dark blue walls and yellow lighting from a chandelier, and tons of other lighting, but the chandelier and blue walls were the most noticeable. A serial killer was after me, he was about 5'8 with short brown hair, I couldn't really see the face. At one point we went to a store, but the layout was different that normal. I was left behind in this store because I told my parents to.
