I get nonspecific hallucinations, like constant moving walls and floors, color rainbows with symmetrical moving shapes tiled across my vision which gets excited when more manic.
I've seen things more specific when up too long, but I knew that they were unreal and just watched like it was a side show. I attribute all that to the bipolar in me.
It's not uncommon to have overlapping diagnosis of which I'm sure that you are well aware of. As far as any other possible MI, I couldn't tell you. Sorry.
I read your story earlier, and I hope that you find your answers soon.
