Holes in the Head

Now that it has actually happened - overwhelmingly and tragically so - I guess this post is almost sub-trivial. For a number of years now I have had an occasionally reoccurring nightmare where I am standing outside my home (with my family) and watching this massive wall of water rush towards me from the sea. Now we live quite a few kilometers inland, but the sea is still visible from here. One child turns to me and asks if there is anything we can do - and I know there is nothing except to hold tight to each other...

Just the other week my daughter mentioned this same dream to me.

Is this a primal fear we all have and, if so, I can't help but wonder what, in our deeply hidden collective past, engendered it?
