I have to confess Derren Brown has gone up in my estimation. Just based on his shows, I thought this stage magician/mentalist was rather a pain, but his recent series investigating various paranormal claims have shown him to be an effective sceptic and (apparently) quite a nice guy. Two interesting points came out of his recent piece on ghost hunting. One was a shocking statistic. Apparently nearly 50% of the population believes in ghosts. That doesn't surprise me, it's about what I would have guessed. But was does it that it seems this has quadrupled since the 1950s. Now that is worrying. The other was when Brown was dealing with an American ghost hunter (or demonologist as he classed himself). I was fascinated by the way Buffy style fiction seems to have taken over people's lives. It's fiction folks! We had a house with demon possession, where the owner was certainly seeing things. But it was also a house with a picture of a demon on the mailbox and the word HATE...
