They're just dreams... Right?

Braylee is a normal 17 year old. She goes to West High School, she does fine in school, etc. Except there's one thing, she's been blacking out randomly and having strange dreams. At first, they don't bother her then after a while her dreams become more violent. One day, when she blacks out, she dreams she gets hurt and bruised her thigh. That night she finds a bruise on her thigh that she dreamed she hurt. As her dreams seem more life like she becomes more distant from everyone, hoping these dreams don't become real life.
