Intruders

I dreamnt I lived in an apartment, and when I'd come home from work, there would be strange men in my apartment. A different one every time I came home. They just walked around like they owned the joint and told me if I said anything to anyone they'd kill my dog. I called the police but they would do nothing. The dream was a series of me driving home, finding a man there, and trying to find a way to keep them out. Disturbing dream, really.
