I accidently got shot by the Sheriff, who was Caroline's mother. I died when it happened, but my girlfriend in the dreams was a witch and brought me back with the help of some dead witches. The consequences of bringing me back from the dead left me as a Medium.
When I had these dreams, I woke up with the bullet wound and would have bled out if my sister hadn't been home. When I woke up in the hospital, my parents' ghosts were there.
