I like the idea of connecting lunar sway to a "childish" mindset, as it is deeply intertwined with the player's subconcious, which would be shaped primarily based on their upbringing and the values and morals they learn early in life. You make some god points regarding the made/unmade beds as well. That said, I do not think that Prospitans are always predisposed to being "like punching bags". Vriska is a prospit dreamer, for example, while Feferi and Nepeta are Derse, which would not fit this pattern. admittedly, these characters are already outliers on their moons, but Vriska is a strong enough example to make me question this. While Prospit as a planet does tend toward surrender, to me this seems to be a result of their prophecy-based society that lives under the shadow of an inevitable defeat. I don't think this would affect the dreamers, though, as their fight against the derse is separate from prospit's. Prospit plays a very small role in a typical session compared to derse. I do not have a particular method for diagnosing lunar sway, I mostly just go off of vibes.
