I know this feeling all too well, every time I close my eyes I hear everything I don't wanna know over and over and over again until my mind melts away to sleeping. Gorgeous as always, and I love how such a dark idea is represented by such a 'free' creature as a bird.
Oh, I'm so sorry you're having sleep woes. Been so very there, and done that countless times. I feel your pain. You tell your thoughts to just shut the fuck up so you can get some sleep, but sometimes, they just won't listen.
The horrors of one's own mind are seemingly endless. We find beauty in pain, and maybe it's because we feel that the people who feel it are learning from it, but I doubt that most of us think that. I think it makes a good story, or even a good poem, and we praise art, regardless of whether it truly speaks to the deepest horrors of ourselves or it is simply "Fun Time with Words." Even if I don't relate to the poem, I can understand it. I always provoke the thoughts which grow in ferocity.
