The strange woman

One day i was sitting in my bed when something strange happened...
 All started when i was little. I started to see some strange movements when I was sleeping, I felt like someone was breathing on me. I never discovered what it was. Up to now.
 At this moment, I am an employee of a 7eleven supermarket. One night, when I was closing it, I saw some strange woman sat in a box that contein cookies. When I went near her, she dissappeared. I was so scared that I went running to my house. There I started hearing noises, so I phone my friend James that knows some things about ghost.
 He told me that a hundred years ago in this house there was a young woman who was killed. So she returned when a hundred years passed, to kill the person who lives there.
 It was like a terror movie. It was so scary.
 That night I started to hear a woman`s voice shouting to me. When I turned arround. She was there with brown and preety hair, and  blue eyes, she started to come near me and, when I saw her hand, she had a knife. I started screaming, but nobady listened.
