Deep within your mind, it's dark and very cold No-one can hear you scream, so don't stay there too long All the walls have eyes, they watch you as you sleep And if you hurt their feelings, they will start to bleed They seep from deep-within, onto the blackened floor You'd better run, don't ever hide, don't ever close the door They creep up ever-closer, rearing for attack These monsters aren't forgiving, you'd better watch your back There's a monster Inside you, don't ever let him out There's a monster Inside you, you're terrified no doubt There's a monster Inside you There's a monster Inside you There's a monster You're trapped now in the mines, I'll never set you free It should not have come to this, for the better you must stay You are all the eyes, you are the blackened floor So sad to see you perish, I was the one that you ignored There's a monster Inside you, don't ever let him out There's a monster Inside you, you're terrified no doubt There's a monster! There's a monster! There's a monster! There's a monster!
