My invisible man

This story will be great soon enough, if you read this, please give it a chance :) thanks.
J suffers with nightmares, the name 'J' is short for Jackie. But what 16 year old girl would want that as a name in 2012? Right? J's nightmares are always the same ones, but in different situations, she is always being chased by the same man. She gets a text message one day, the person wont tell her who they are.. could it be him? When J sees the man in her dreams in real life outside of her school one day, the games start to begin, and her dreams become reality, but with a twist.
