Dr Wiseman
Dr Richard Wiseman got people to go to spooky sites like Hampton Court Palace and write down what they experienced and where they felt it.
Weirdly, he reckons that although ghosts don't exist, hauntings do!
He says that people do feel odd things, like chills or strange noises, which make them think there are ghosts around.
