Beware of the Darkness

As I ran down the dark alley in the cold night with only a crescent moon to light the way, I looked over my shoulder, big mistake. I tripped over a fallen trash-can. As I hurtled to the ground I saw him running, getting closer. I scrambled back up but it was difficult to run in high-heels. He was faster then any man I've ever seen. I kept running and running, but he was always behind me. But every alley has a dead end. I saw the tall brick wall in the distance. I almost slammed into it trying to stop. I spun around and there he was. He had reached me a second after I turned. He pressed me forcefully up against the wall. He gave me a evil, toothy, smile. He had fangs. I gasped. He jerked my head over to one side to get a clear shot of my neck. He licked my neck, going up and down like a snake, then plunged his white fangs into my neck. I could feel it when he tore through my soft tissue skin. I could feel a few drops of blood he missed oozing down my cold skin. Just when I thought I was done for, I heard another man's voice.
"Sam, stop! She may be of use." The man named Sam. Suddenly stopped drinking my blood and turned to the shadowy man. He came closer and looked at me. "Oh yes, this one's a keeper." Sam let me go, I fell to the ground. "When you wake up everything will be better." The other man said. My eyes were just slivers now. As I laid on the cold, asphalt of the ground, I blacked out.
