I was sitting on the ground listening to family talk when I started to get very dizzy, & fuzzy I had the sensation that my brain was vibrating & I was about to black out. It lasted just under 10 seconds, I don't think anyone noticed. Seconds later I felt fine. Not sure if its related but I have had increased nausea & lost most of my appetite. I have had many odd things happen before but this was a first. Any ideas what may have caused this? I've never heard of this before. Has anyone experienced this? I have an appointment with the dr tomorrow.
