Cover art for Ode to Sleep lyrics by Twenty One Pilots

This song seems to be the basic cry of an insomniac. It beautifully portrays the intense struggle one finds himself in once he lies down for sleep. You start to think about everything that has gone wrong, but most of all the wrongs you caused. Mind racing and "demons yelling", one also finds himself in the perfect position to write, as there is rarely another time when an insomniac's mind will bring forth as much information as when said person is attempting to sleep. However, once the writing begins, it is hard to stop in time to get the amount of sleep you were aiming for, therefore placing anxiety on the fulfillment of priorities, such as work. It is at this moment that the decision is made to stay awake. The "dark" can't take prisoners that don't sleep.

My Interpretation

@pacman212 I think your interpretation is great. I can feel it, it's kinda like in my case (can't fall asleep -> writing and that's the weapon against those 'dark' thoughts). Though my favourite interpretation is about Tyler talking to God, I think both - this one and yours - might be connected.
