The monster head...I feel like it defines something more than what meets the eye you know.
Maybe how other people view you eventually changes you, even if it's only on the outer surface- that in turn does become the very thing, that defines 'you' although it's a fake. Somehow your mind enforces you to embrace it as reality and at last, you're stuck in a never-ending path of self-degradation and too start seeing your true self as 'the monster.'
Well, that's only a thought of this silly me, not even a proper theory. But it's fine, right? :')
