Sometimes there are rumours about extraordinary, even mysterious events that give us the creeps no matter how erudite and rational we happen to be because – if only for an instant – they make us speculate what would be if it were true. Authors even like to toy with such musings in books and films. Take for instance zombies, revenants and vampires. For us today they may be delightfully scary creatures because they belong to the realm of superstition and ancient religions, but for our ancestors it was a real threat to be haunted by one of these undead or even worse to become one of them instead of passing on into eternal life after death. In the modern Serbian novel Fear and His Servant by Mirjana Novaković the Devil himself travels to Belgrade out of fear that the vampires whispered about all around may be real and presage his impending end.
