Fade Like A Shadow Lyrics

Cover art for Fade Like A Shadow lyrics by KT Tunstall

"You've got a vampire on your neck, Everybody knows what happens next

You fade like a shadow, fade like a shadow, fade like a shadow, fade.. Fade like a shadow, fade like a shadow.."

These lines make me thing of the whole Twilight Saga book/movie because when Bella meets Edward she totally leaves behind all of her other friends.
So "You've got a vampire on your neck" is like this person has met someone and they are starting to fade from everyone else's lives by only focusing on the "vampire."

The other person has found someone new, and is therefore fading from the singers life.
