Nancy,
I think there is a fine line between your dreams of death. When you dream about your daughter dying, there is a birth of a baby. So, death=birth, in this one.
When you dream of the mable place, the result is a death, with no births involved. See what I mean?
As for the one where your grandfather was wheeling your grandmother in the wheelchair, I believe you had a specific premonition, although it came through in a round about way. It became a lot clearer to you when your grandmother actually lost her leg, ya know? You were only 8 y/o, so I think it would have been tough for you to put 2x2 together. Grandma had diabetes, yes? Is that why she lost her leg?
