You are so lucky to be here....my mother died from one of these. She was in the hospital at the time, they had been running tests on her all day. She woke up dizzy and my Dad took her in to be checked out. They found nothing and had discharged her....she was waiting to go home when she died.
6 months later....my Aunt died from the exact same thing.
So...you obviously have something to do here on earth before its your time.
