@ashnoodle Interesting. I am not sure there are notes on there regarding PGS. I *did* do a series of extensive threads here on Mastodon that I intend to make into a page over there, but I haven't gotten to it.
The best way to find it is to search the #PsychedelicGhostStories hashtag here and then scroll down until you find the posts also tagged with #ProductionDiary -- sadly, afaik, there's no way to limit the search to posts that have both.
I will make a page at some point, just haven't yet.
