There is Persian lore of a type of vampire that is known as a palis (“licker of feet”), and as its name implies, it attacks its victims at night while they are asleep by licking the soles of their feet until they bleed. A palis by the name of DACHNAVAR once lived in a valley in the desert, and it happened upon two men who had fallen asleep foot to foot and a blanket covering them. When the vampire tried to attack, it believed that it had come upon a man with no feet and said, “I have explored 1,033 valleys, but have never seen a man with two heads”.
