Spitfire - Heroin lyrics

I am the shrieking in the back of your head I am the child scratching at the walls of your basement I am what's buried in your back yard I am what's underneath your floorboards...watching you I am your sickness I am your cure I am your dark side I am your nine to five k**ing spree I am lucifer's right hand man I am your right hand man I would do anything to be five years old again I know i can't change things, but i know You can do the impossible Make them understand me Make me understand me
