It makes me chuckle that the little PSA post I did yesterday got more comments, and more engaged comments, than much else I have written here. Clearly, I have to put a stop to that (I jest) and the only way to do that is to talk about the reasons why the Saadia tree came across as a bit of a revelation for me. This should be straightforward but more schematic than content rich. This is going to be a little fast. And you should expect tangents.
Way, way back in the early days of my time on the internet (ca. 1994-95), I had the good luck to stumble into a dream interpretation community. It was a simple affair. Every cycle (I can’t recall how long that was, maybe a month or so?), everyone in the group would send in a dream they wanted to work on. The organizer would choose one or two (at random or by design, I can’t recall), and then the whole group would go at the dreams.
