I have learned that sometimes we need outsides forces - you might call them omens, intuitions or hunces - to give us an inkling of the future as well as what it might contain. Just as a species, we are unfortunate enough to not be able to rely as much on nature to give us just warning before something happens, like the rest of the animal kingdom.
The newest one I had happened yesterday as we drove to town. There was a brown cow alone in the field, close to the fence edging the road and right behind her, laying on the ground, was her newborn calf still wet. As we came up, an eagle that had been perched on a fence flew up and circled above them as the cow ate the afterbirth then circled down into a dry bed.
Those that I have talked to also think that this is a sign but we are unsure of what it is. All I can honestly say that I know of the experience is that it was a wonder to see nature at work as well as it was one of those once in a lifetime events. I am going to be trying to figure out the meaning but if anyone might have an idea, I would love to hear it.
