Looking forward to it if you decide to post your own!
As for darkness retreats... I wouldn't have heard of them either if I hadn't started searching to see if there was such a thing as meditation retreats in deliberately darkened spaces. Turns out there's a whole lot more to this topic than I ever imagined. Some religious traditions have organized dark retreats for a long time.
(This always seems to be the outcome when I investigate a new interest: wow, I had no idea there were so many rabbit holes!)
Anyway, if you'd like to read more, here's a good place to start.
