I was sitting on the couch when i stood up to give my boyfriend a hug goodbye when i felt dizzy. From there he says i fainted. I laid there with open, "dead eyes." I felt my body jolting and then opened my eyes. I stood right up feeling good as new. He says there was no jolting or shaking though. What could that sensation have been? I know I felt my body shaking very hard. The only medical history I have is Mitro Valve Prolapse.
