i have migraines but have not experienced this. however i have heard about this from other people. there is a migraines community on webmd where you might be able to get answers from other migraine sufferers but i do know that you are not the only person who has experienced this. hope you feel better. <link>
is it possible to have depersonalization symptoms after a migraine attack? . july 2012 - had my first optical migraine attack. symptoms occured for about 45 min. before the actual headache. felt better after taking advil and resting. 1 week later i began to notice depersonalization symptoms. felt like a ghost like i was floating around. or watching myself on a movie screen. everything feels like a dream. in and out of reality. i can't grasp reality anymore. i'd sometimes feel pressure in my head.
