 The brain rewires for nocturn, for night, so when the darkness comes, all sorts of pathways in our brain, some will shut down and some will open up. And that seemed to be why so many of us in the past, and so many now, and men and women, often find it a really creative time. So it's not just the silence and the lack of distraction, but it's also that your brain is working in a very different way and making very different connections and sort of dipping in and out of your memory in a way that doesn't always happen during the day.
