Wow, I've never had any sort of premonition dream like that, but I have had some dreams with Sandy in them after she died.

One happened about two weeks later and, in it, she ran to me, wagging her tail and licking my face--but, in the dream, I knew she was dead! I believe it was her way of saying, "It's okay, Mom. I'm not sick anymore (she had cancer) and I'm at peace." That was very comforting and touching.
