I identify with this. I love walking at night with the stars and especially my friend the moon, especially more so when the moon is bright enough to create my friend my moon shadow. There was a period a couple months ago when I could barely sleep at all. I felt dissociative to the point that sleep was uncomfortable and going for walks would stabilize me. Here are two poems about the same walk one night--the subtitle of the first is so in-tune with your story tonight--"Poem Inspired by my Muse and a 17-minute walk at 2 am under the stars"
