I had an elaborate dream that included my dead grandfather. At the end of that dream, he was dying again, but from something entirely different, and he was still conscious. He told me to check on my grandmothers farm for leaks in their water system that went to the fields. The next weekend when I was down visiting them, I had learned that one of the pipes that went to one of the field faucets had busted and my uncle was working on fixing it.
I chalk it up to coincidence. I mean seriously, my grandfather isn't going to pass a message to me from the afterlife about a god damn water pipe.
