Maybe it's the electrolytes. An electrolyte imbalance can lead to a situation that mimics the symptoms of a stroke.[0]

>For me it's more like a moving shade that makes it impossible to see what's behind it rather than not being able to recognize it.

Are you aware of the shade or does it behave like your blind spot? Because I've had a few instances in my life where it felt like my blind spot took up a much larger portion of my vision. I've also had the shaking then suddenly starting to profusely sweat that goes away when I eat something.

I've had this about three times in my life. The first time I thought I was having a stroke and went to bed, in the hopes it would go away. The next morning I was alright.

The second time happened at work and a co-worker brought me to the hospital. Turned out I was having a migraine attack with aura.

The third time happened at work again. I took an aspirin and took it easy for about an hour. My project manager asked me to go home, but that felt more troublesome to me than just sitting it out.

Man, that's terrible. What happens if this hits while you're driving?

i get something close to this before I get a migraine: https://images.app.goo.gl/XS938pFYT6a2Juuq7

starts as a small spot right in the "centre of vision". then it grows until I can't see anything at all.

Then vision comes back and is replaced by a headache so bad, even the tiniest movement hurts like a knife cut.

Then I sleep between 4 and 12 hours. The day after I'm something like hung over and the day after that it's like nothing happened.

Luckily, I don't get it often any more :-) But it's hard to explain to other people when it happens.

the good thing about the aura is I get a warning what's about to come, usually it means I can get home before it breaks out.

I can only remember once when the headache broke out before I got home and I started sobbing like a baby on the bus. An old lady worriedly asked me if I needed help and I don't really remember how I got home.

I assume we're talking about scintillating scotoma here - you have about a minute to find a safe place to stop until the "blind" zone grows enough. But yeah, this precludes the bearer from piloting mechanisms that can't come to a stop within a minute.

The blind spot portion is what I've experienced, but none of the rest. No flickering or even noticeable expansion. I was a kid at the time and was playing an FPS. At one point I realized that I could see all 4 corners of the screen, but a certain sizeable area inside it was not visible without me moving my eyes. It provided for an interesting gaming session, but did go away rather quickly.
