If a place existed that was known to have haunted ghosts in them, then I might spend the night there if I wasn’t by myself. I would need someone else there. Also, the more people who are there that night would be better. If I had to spend the night in a place where people say that there are ghosts and I had to spend the night by myself, I would most likely not do that. Also, it would depend on the type of house or building that it is.
If the haunted place is a bed and breakfast or a house that is currently in use, I would more likely stay there. However, if it is an abandoned house or insane asylum that has not been in use, I probably would never spend the night there.
