Voice 1: Vampires are imaginary creatures. They exist in films and books. They have human-like bodies. And they usually have some kind of supernatural power. They survive by drinking blood - at night! Vampires bite their victim's neck with their sharp pointed teeth. Vampires are not real. They do not exist. But the vampire bat still takes its English name from them. This is because the vampire bat survives by drinking blood!
