I have these really short flashes during the day where I can't see and it feels like my brain won't work. It feels like a split second of nothingness and pure confusion. It's like for 1 split second I can't understand anything and I can't feel anything. Right after that split second I feel like I'm catching myself, and then I forget that it happened. This happens multiple times a day- but I can't count them because the confusion and the forgetfulness usually occur right afterwards. I think thays has only been happenig this year. Can anyone explain what this might be?
