if you're looking for a psi vampire, who is a human who can drain energy from others, then you'll probably find on here.
if you mean a sanguine vapire, a human who lives a vampiric lifestyle, you might be able to find one or two on here, but they're human.
if you mean a twilight/Dracula blood sucking vampire, they do not exists physically. anyone who claims to be one, or was turned into one, is lying to you. you were born a human, nothing can change that, not even magic. magic is energy, it cannot go against nature. this all being said, i am told they are astral beings, so try looking into astral projection to speak with them. i believe i saw a summoning spell somewhere on the site once, but i don't know if that would work or not. i don't work with vampires so i wouldn't know if one could be summoned.
