mind over matter

Knock, knock, knock  On the walls of my mind  Feeling stuck; Lost in time  Thoughts are fueled by dark matters  Succumbing to madness, like that of a hatter  Constant battle between voice's chatter  Repeating, repeating; Mind over matter  Dreaming up plans for blood spatter  Forced to control self, contain the urge  They whisper, mind over matter  Such is sure to be my downfall  Details vaguely recalled  Feeding the beast, cause for enthrall  They beat me down; Refuse to crawl  Persitance confuses  Stand tall and brawl  Last standing loses  Still, pride won't let me fall
