Call a psychic, find out if it's evil. If it is get the place exorcised have your son stay at someones place for a while until it's safe
I see ghost in my house.but it's all black. It looks like it's stares at me and my son. One time i saw it float pass my head. It happens every night. My grandma and uncle have different experience too. In the same room i use to sleep in?
These things always happen at night, could be hypnagogia.
