I think the worst dream that I ever had was one in which my daughter had died and I had one last chance to call her in heaven and say good-bye over the phone. As long as I didn't hang up, I would be connected to her, but as soon as I did, that was it, I couldn't ever speak to her again. I just remember her little voice on the phone saying "Bye-bye, Mommy," and me sobbing and begging her not to hang up. I woke up crying, and almost cry even THINKING about that one!!
