When a newspaper reporter's dreams are haunted by a ghost, he must find her killer to stop his nightmares.

Why not a cop, a detective haunted,metaphorically and literally, by an unsolved murder?

The newspaper reporter doesn't add to the story at the moment, a man, works and removes unneeded detail. You now have room for detail that moves the story further action and goal.

The girls ghost. You find out who the killer is later.
