Heroin

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 killing 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
