Vampires exist, but are nothing like what is depicted in popular culture.
"Among the most abominable products of Lilith, it is opportune to cite the case of Count Dracula in Russia. This movie’s personage truly existed, and H. P. Blavatsky comments about him in one of her books. This great female Master stated that such a Count (in times of the Czars) was the Mayor of a certain Russian town. He mortally hated his wife, because vampires are homosexuals; they mortally hate the opposite sex... An order of vampires exists in Palestine; they hide themselves behind the following title, “Order of the Immortal Guardians of the Holy Sepulcher.” Vampires are the outcome of homosexuality in combination with Tantra between persons of the same sex. It is an execrable monstrosity, a frightful abomination." - Samael Aun Weor, The Doomed Aryan Race
