Nightmare Attack in Dangerous Detroit Streets

was in Detroit or some rundown city like that, on a work thing. Was staying in an airbb with a very flimsy front door and didn't feel safe at all. As night set I heard the dangers of the night coming out, screaming, some gunshots, loud crashing. I went outside to go to the store for some reason and in my way back some girl with a circular saw cut me off. She had a bunch of scars and looked crazy/on drugs. She was fast-zombie fast, and lunged at me and just missed me and I started running but she caught up to me with a thud on my back and I went down and then she took the saw and dug it into my left thigh and blood and pain started shooting everywhere. "You'll never run away again!" She cackled. Woke up. Don't want to go to Detroit.
