Why does she do this?

This girl is so mean. I do nothing to her, but she keeps on talking about me on her myspace whatever. When I am driving it seems she always is there. She just recently followed me on a two hour trip. Like she follows me sometimes when I am driving and the next day there will be a quote not syaing my name, but about me on her myspace. She follows me when I drive, she just knows where I am going it is spooky. Why cant she stop talking abt me? I mean I do not know her. Her bf and his best freind went to school with me. This is insanse.
