I got my first migraine this year, in my mid thirties. It wasn’t a particularly bad one, but I had visual hallucinations beforehand that were really weird and worrisome. Like an expanding ring of colorful noise that eventually expanded larger than my field of view. It was definitely a brain hallucination, and not an eye hallucination, because it was exactly the same in both eyes.

The weirdest thing was when it was obstructing words in my vision, I could still read them. Like, I could read an article on my phone, but I couldn’t see the words I was looking at. Definitely incredibly weird.
