Voodoo Doll

The last girl I want to be infatuated to me is a witch disguised as a creepy teenage girl with a creepy doll. The statement seemed absurd, not because a girl is infatuated to me (hey, girls like me a lot), but because I really don't believe in the existence of such mythical creature.
But absurd as it is, how could I not say she's not one, if it's pretty obvious I'm the latest subject of her wicked magic spell? When you're quite sure you don't like someone (hate her, even) but you think of her every hell of a second, and every night it's either the thought of her keeps you awake or she appears in your nightmares, you're definitely under a spell, right?
