Vampire Existence?

Have you ever wondered of the existence of other creatures besides our own? Well, history or even mythologies tell us that they do exist and have existed. These ghosts and poltergeists, elemental spirits, vampires and werewolves, and others, have been with us for long centuries now according to paranormal experts and psychics.

I know for truth of the existence of a sect of sort who call them selves energy sucking vampires who are members of the Temple of the Vampire but not these blood sucking ones. But the National Geographic Channel shows us one blood-sucking creature, a male and only devours blood from individual donors (possibly fang bangers..) The video is a testimony of a male who considers himself a vampire. Hmmmm..a vampire or someone who is experiencing a sort of metal disorder or brain damage?  That I couldn't exactly tell.
