I had a terrible migraine headache for three days. Started seeing lines in my vision, halos everywhere on lighting (still having this problem), and lights seem insanely bright. I feel as if I'm stuck underwater and can't seem to get my head above water, or as if I am stuck in a fog and cannot make my brain function. It's like being half asleep and not being able to wake up.

I've had one incident where my vision went blurry for a few days, due to a bad dream, and pressure in my head.

Has anyone else experienced a loss of function in their ability to think, react, or see due to a migraine??
