I remembered bits from the episode: Apparently there were a bunch of supernatural things going on in this house. If you went down a hallway too far and got too close to a room a ghost could grab you and he'd take you inside the room and kill you.

Here's the important part:
But there was this one guy, who talked about how he was followed by this spirit "THE OLD MAN" his whole life, and that above all else it wanted to kill. He ended up getting forced by another character into this room at some point and he instantly died.

Sorry for the wall of text, I really appreciate your help!!!
