[learnin to learn]

what got me hooked on the whole vampire theory was Anne Rice's Vampire Chronicles.
Then I watched a show on the history channel call Vampires: fact or fiction. It showed people that actually drink blood, but it is like an aphrodisiac. Then the show talked about a man who slayed 10 people and drunk there blood.
What would people like these be called? At first I thought to call them cannibals, but they do not eat other humans, they just... drink their blood.
