Happened to my Mom when her dad died - Her sister had moved to California some years before (we were in NY) and the sister called Mom about 4 in the morning NY time to say she had the weirdest dream where she woke up and saw her father standing at the end of the bed giving her a sad look (she had been kind of a wild black sheep of the family) and felt something was wrong. Mom called Grandma and woke her up and it was then that Grandma discovered Grandpa dead in his bed - massive heart attack...
Great thread, FReepers. I knew I woke up early for some reason.
