My Worst Enemy Part 3

Crash! The sound of glass falling to the ground. I turned to see what looked like a human head, slightly ripped apart lying on my floor. I peered acrossed the way to see the other window of another room, someone must threw it. I ran closer to window and saw what it looked like was another person. They were trying to get my attention, was i not competely alone?
I yelled out the window into the deaf ear of the moaning undead. Nothing in response, i stuck my head out my window and realize that hope of not being alone was shattered just like the broken glass. Their bottom was gone, there whole waistline down was torn off, i looked down only too see the slow crawling of the undead walking towards and around my building.
Boom! i was thrown back on my ass from being almost outside my window. What was that? Something must have hit the building, i stood up and saw a car fully engulfed in flames on the first floor of the building. I could feel the heat rising up the building from my fourth floor, i moved back away from the window and towards the other side of my room.
I started hearing the sound of the hindge breaking some more, i felt something grab the back of my leg and started pulling me closer to the door....
