Vampire neighbor?

Okay. I am about 58% sure the guy who lives in the apartment above me is a vampire. 'Why do you think he's a vampire?' you might ask. Good question. Well, first off, the guy never sleeps. I go to bed at 1:00am, he's up. I'll wake up around 5:00am (for randomness), I'll still hear noises (and the guy is loud too!). Then I'll wake up around 8:00am, and guess who's up? Yep, good guess. Secondly, he coughs like he's about to throw up every day of every week. Okay, that may not have anything to do with the fact he's a vampire, but it's really annoying! Anyway, even as I write this, I can hear him making noise. Like I said: never sleeps. So I've come to my conclusion: definitely a vampire.
