I'm about to write something that is not at all my usual bag but here goes.
It's a dream thing and I apologize but it was intense.
I won't give all gory details but the gist of it was that when I woke up I got the impression that perhaps the "Watch the Water" clue might have something to do with bottled water companies transporting bodies in the hulls of the boats or even in those HUGE bladders you see them using to move large quantities of water.
I don't even understand what it means but the dream was so odd and the revelation felt visceral so here I am sharing it without any sauce or anything to go on.
