Hi, I felt like that for months on and off. I started to see that as one of my signals that I needed to rest and that my brain was not able to handle any more. It is a weird feeling and almost never happens now, but only after learning the hard lesson of resting to allow my brain healing time, lots of time! The brain shuts out what it can't handle. I was worried about driving like that, would not think it's safe.

Hope this helps some
