there have been more than 200 cases :s i was interested/intrigued by this a few months back. there are lots of speculations about how this could happen, but none have actually been proven. I lent the book with lots about it to a friend, so i cant quote directly, but as i recall.... in most cases, the flames barely even mark/damage the persons surroundings, e.g. one woman died while in bed. and there were no burn marks on any of the sheets. freaky stuff O_o rare. but it DOES happen (Y)
