I haven't. When I moved into my apartment in the sky, however, I told the potential ghosts I'd be cool if they were.
That house is awesome. I love old spooky-vibe houses. There's a house in town that looks like an illustration straight out of a children's book; it's that much the epitome of a haunted looking house.
I do remember a guy I knew swearing he'd seen a ghost on the fourth floor of the old factory where I worked. My ex said "Oh, I don't doubt that he
saw a ghost, I just think it was a figment of his psychosis."
Has anyone besides your cousin seen or felt this ghost?
I'd be more than happy to camp out there for a while and let you know if I see one!
I love scary scary.
