I Gotta Know lyrics

I gotta know Tell me now I don't get it I wanna know Walking down the street from my pad I'm safe and sound in my head Keeping up a smile full of dread Everyone around me is dead I gotta know Tell me now I don't get it I wanna know Never thought I'd see what I saw People screaming something at the door I can hear it all breaking down Don't you even make a sound Yeeeaaaaahhhhhhh!
