I don’t really believe in the supernatural very much at all, but I did work in a retirement home, and there was an old lady who would call me all of the time for assistance. One time she called me to tell me there was a girl in her room. I went, and of course, nobody there. Can't say it didn't make me nervous to check around in the room though. I asked if the girl was nice, that she saw. She said "Yes! very nice!" So I told her essentially "That's great!" and to have a good time. She seemed a lot calmer after that. She was a school teacher in her working days.
