Already lost the words and most of the details, but dream brain just hit me with an animated disney movie style musical piece about two-phase menstruation in fairies.
They were having some kind of festival celebrating the first time (biological details, apparently the entire species was synched up) for their latest generation, and the queens (there were two, for a specific and related reason) burst into song.
Wild thing, production values were top notch, what little I can remember suggests the song was solid in lyrics and whatnot, too (sometimes dream brain does song writing/composing... if I could remember the damn things I think I'd make a mint 'cause it's remarkably good at it).
Anyway, one thing that stood out is it was basically friggin' yin-yang themed. When it starts, their lower halves go two-toned black and white in color, split down the middle, and each side had different characteristics in exactly what happens on flow. It was the reason there were two fairy queens, even, 'cause while the critters in general ran the gamut of pastels for normal coloration, like you'd expect from a disney movie involving fairies, the royalty was split into paired monochrome.
... any case, what the hell dream brain. I have great respect for the thing 'cause it's basically never done me dirty and it's consistently amazing in output, but sometimes the thing gets weirder than usual. Great worldbuilding and production, as usual, but... still. Still.
