Portends of the future

Over the years I have been privy to visions of the future.  Often, I don't understand the importance or the context of these messages until the moment in the future when they come into being.  Most often actually.  

What is the point of seeing what may happen if you don't understand or can't do anything about it?  Is it really a heads up?   Is it my own lack of perspective that I don't understand the message?  Is the point that when the event comes about it is divinely guided?  Often I find that the moments I can pick up on are emotionally charged ones, or regular things happen in an emotionally charged time.

A vision of a man pointed at the road would have saved me from a tire blow out from a pothole.   I ignored myself, a friend of mine listened, but I ignored myself despite his inquiries until it was too late.  

At Samhain of 2012, I delivered a message during a seidr to my husband of very dark times ahead and loneliness.  Did I forsee our divorce or just hard times ahead?  

Hades told me I would not descend into the darkness the year and to stay in the light and seek my joy. Did He forsee my relocation to the sunshine state?

Many a Greek tragedy tells the story of the vain attempts people make to avoid a foretold destiny.  In there responsibility in this power?  Is it about trusting the message?  

Things that vex me....
