When the Doctor woke, everything around him was strange. He struggled through the fog of his mind, and finally managed to see his surroundings.
"You are stronger than I thought" said a voice, only thing it was his.
"What have you done?" he stuttered, only hearing it echo around.
"Most people taken over like you would have collapsed into themselves, but not the time lord, not the Doctor, you make yourself known, but you don't die easily."
"You bet I don't."
"Ahh, but that will mean you are self aware, you will see everything that is happening, though little good it will do you."
"What is that supposed to mean?"
"This body is mine now, it will always belong to me, and you will remain, though in time you will probably do what all others would and revert into yourself, but just know this, you are trapped inside me."
"But like an irritating bee, I won't let you forget me" the Doctor seethed, "I will be here every day, and one day I will win control of my body again."
"Maybe, but by the time you are strong enough, you won't want your body anymore. Once it has tasted blood, then it will be tainted to you."
"What do you mean, tasted blood?"
"Well, I am a vampire" the voice that was the Doctor's said. "Now where shall I go? Oh I know. I will go to that little planet you love, the Earth. I bet I will find some tasty delicacies there."
