When I am hiding all alone in the night I hear these voices going round in my mind I am such a mad girl Living in a dream world When I was seventeen, I was afraid Of all the creatures lying under my bed Shooting with balloon guns Pink and green and blue ones Monsters in my head When there is something going on in the dark I'm feeling every single beat of my heart Every single heartbeat Is making my skin creep When all you zombies wanna come out to play And I know they're gonna take me away I am going crazy Am I going crazy? Monsters in my head (In my head, in my head, in my head) (In my head, in my head, in my head) (In my head, in my head)
