Vampire's Kiss

I walk the streets at night I am an enemy of the light You got what I need You give me life when I see you bleed Is this happening? Is this real? I spill the blood Feed the greed (need) Spreading evil I am a vampire I summon hellfire You need to set me free You give me life when you kill me? Is this happening? Is this real? I spill the blood Feed the greed (need) Spreading evil Why?
