There's no such thing as real vampires. ( the type that drink your blood ) but there are such thing as vampires that feed off of your energy.
For love spells, I've learned that if you try to make someone love you against their will, karma will come back. An example would be if I've made a guy that didn't love me, love me by casting a spell, there will maybe be some consequences. Like the guy becoming obsessive or maybe just hating you. That's about all I can explain on that. Correct me if I'm wrong guys. n.n ~Shadow
