I have TONS of weird dreams...just try to not think about your daughter too much when going to sleep, let your mind relax. You might be a little concerned about your daughter...try to keep those concerns and all to the daytime. :)
7 billion or so people dream dreams every 24 hours and even if a very small percentage of these are dreams about people they know dying, that's still a lot of dreams about people dying. Even fewer of these people dream about the death of someone who actually ends up dying but we started with a pool of 7 BILLION people. Even a tiny, tiny percentage is still a fairly large number.
