Vampire

Vampires are mythological beings who subsist by feeding on the life essence (generally in the form of blood) of living creatures, regardless of whether they are undead or a living person.Although vampiric entities have been recorded in many cultures, the belief in vampires and bloodsucking demons is as old as man himself, and may go back to prehistoric times. Vampires were generally referred to as cold beings who could be destroyed by daylight. Holes appearing in the earth over a grave were taken as a sign of vampirism. There is no scientific evidence of vampirism except the Vampire Bat.
