> No one “hallucinates coherence”, hallucinations are by definition a perception which does not match reality.

I don’t know how to put it well, but… Have you ever had a moment where you realized your perception of something was off and things weren’t as you thought they were?

Have you seen people dead sure of something you were positive as nonsense?

I have, ranging from simple small isolated situations to whole worldviews. I have personally held mental models that were broken, but felt consistent and true. I still sure do, just don’t know (hopefully, yet) how they’re mismatching the reality this time.

Call it “delusion” or “hallucination” or “misunderstanding” or something else - it’s still a thing and it happens in language-capable humans and machines alike.
