What people refer to as "ghosts" are Demons. The bible says that once a person is dead they are conscious of nothing. So there is no hell they don't come back they don't breathe they don't take form on the earth in anyway shape or form. They simply do not exist in anyway. As far as hell goes if it were true then the spirits would have to be alive in some way to be tortured. But since they are Conscious of Nothing then they couldn't be sentenced to Hell. Just a grave. It maybe fake but then again so is Ghost Hunters and I know that cause I saw how they set it up when they were at the lighthouse in St. Augustine which I happen to live right behind.
