The girl has psychotic episodes every 7 months, then gets stuck in her own mind and must find a way out.

Jack is an odd teen who was born with a condition, a supernatural condition. He's only ever told his best friend about it and now it's finally become a problem. At camp lunch, Jack pulls him aside and he knows somethings wrong. Jack then goes missing and his body is found, but when they go back with the police, Jack is gone. I might continue "Jack" in the future.
