Hungry intruder

I was returning home alone to our house on Cherokee St. I entered the front living room, and although I neither heard nor saw an intruder, I just KNEW there was someone in the house. I walked slowly through the house with only a drinking glass raised over my head as a weapon. The only light was from the stove. I eventually noticed a black woman walking toward me. I threatened to throw my raised drinking glass at her. She slowly made her way around the counter and was positioned opposite it from me. She grabbed a large knife from our knife rack. I grabbed one also and asked, "Do you really want to die?" She leaned forward and simply cut a piece of cake. I told her which door she would be leaving from and she made her way to it. Her husband was just outside the door waiting for her.

I think one catalyst for this dream was that I watched Demolition Man a few days ago. In it there were these sewer-dwelling people who would come to the surface to loot for food.
