This song is about cocaine. -There's a crack in the mirrorand a bloodstain on the bed There's a crack in the mirror and a bloodstain on the bed

One is refered to as a vampire, meaning addicted. They thrive on that vital source.

He call's himself the walking dead, overdone on cocaine.

It's a beautiful song. The mirror is an obvious reference.

Not every song is about drug use. Just because a song says the word "Mirror" in the first verse does not mean that they are talking about doing lines off a mirror. Put the whole thing in context, don't just pick out a single word and base a theory on it.
