I don't know if there is a formal term for the concept, but it seems like there is a quality of skilled authorship where an author's own prose impresses themselves to the degree they believe their own selectively edited metaphorically enriched version of their voice over than their actual, humble I-might-fart-my-tooth-is-sore base reality. They get gobsmacked by their own writer's voice and then their personality morphs to some monster. History has pivotal personalities that seem to fit this pattern of moderately intelligent authors being gobsmacked by the power of editorship, which causes them to elevate their personality into Uberman Insanity.
