A few nights ago I dreamed that I was standing on the edge of a giant sunken waterway, some kind of vast floodwater system in which six inches or so of water flowed at a good clip over cobblestones slick with moss. In it, someone was running around, chasing an animal or other creature.
I was high above.
Suddenly they were down there with my son. They were horseplaying, and they swung him around by his feet and tossed him out into the deeper water. I screamed “He can’t swim you asshole” and desperately tried to plan the fastest route down (it was so far down) so that I could get to him before he drowned. I woke up in an awful panic, which took half an hour to go away.
