Why, You're Only a Sort of Thing in His Dream

Ssssssso after writing my reply to Claude's call for nightmare descriptions, I decided what I really need to do with my time was right a (much) longer version of it. Also serves as a kind of primer on what Spear's current headspace is like, I guess, and is thus a good way for me to errr figure out where to go from here after being hiatused for so long. THAT'S MY STORY AND I'M STICKING TO IT!

( ...In any case, let me start out by first describing a major source of imagery in Spear's nightmares -- Tsukuyomi. )
