ill explane the lore character tortured someone called david. So david decided that he was gonna make character delusional and trap him. And he made the ghost that not everyone cannot see only character since he put a brain chip in his head and character would die to shock because of the brain chip if only he touched the "ghost he was seeing" and if you manage to go to the house and get the good ending, its not over he will come back to trap character (sorry if the spelling is wrong english is not my first language)
