Walls of the Coffin lyrics

I wipe the maggots from eyes As I wake from my deathlike sleep Surrounded by these black walls Lid closed tightly Bleeding from every pore In either reality or a shadow of madness My flesh as one with the rotted thoughts That pollute my skull Through the haze of disturbing depths My veins flow black Sour and poisonous I feel the flesh separating From my desiccated face I am living death I am of darkest origin Screaming as I struggle to awake
