Public Parapsychology recently announced a conference that will be held at the University of Edinburgh on April 4, 2009. The topic: Hauntings: The Science and History of Ghosts.
Here's a link about the event: http://publicparapsychology.blogspot.com/2009/02/science-of-hauntings-conference-in.html
This sounds interesting. Are they going to debunk hauntings and ghosts as wild imagination? Edinburgh will be a good location.
I've visited the city and the castle and there's great atmosphere there. I visited the underground vaults also. Really interesting city. I would love to go back and spend more time there.
