I'm glad you posted about this whoopdedeaux
I've heard of another syndrome, "Alice in Wonderland", that reminded me of hallucinations.
I occasionally have something occur that is like the "Alice in Wonderland syndrome". I don't have optic neuritis, or problems/lesion on the optic nerve. I am, however, a life-long migraine sufferer.
I'll see patterns on floors/walls/clothing etc 'shrink' together - kinda like when Alice drinks the potion and gets tiny, you know? Everything sucks in together.
At first I was just breathless and frightened when it happened, but now I know it's likely migraine, or perhaps the MS, doing it.
Not fun, but it's less scary I find when you can find documentation of it.
