Crumbling is the sonic explanation of delusion, where you're watching and feeling your reality crumble around you. You're delusional, which means that nearly all information is contrary to what you're experiencing. Things are becoming harder for you to understand and cope with and you begin to question your own reality as though you're in The Truman Show. You begin to feel as though the people around you, even the ones you care about, aren't there to help you and allowing them to help you is only going to cause you harm.
