the evidence is hard to deny.
No it's not.
Dunno, have you seen any evidence? I'd provide some, but I can't really think of anything definitive the interblag has to offer.
On a semi-unrelated note:
Has anyone here ever watched A Haunting? It's on the Discovery Channel sometimes. The acting is terrible, but the encounters themselves are interesting. And on the show, they interview the people the encounter happened to, and they are almost always sceptics, but when the whole thing is finished, they usually always become believers, which I think says something profound about first-hand ghost encounters.
