You don’t know how you got there but there you are. Splashing around in the water, nearly helpless. There’s no life raft and no personal floatation devices. Just you and five (six?) others treading water. The water feels deep — you’ve dunked down a couple times and can’t touch the bottom — but you see trees sticking out of the surface as well. (A flooded forest?) Each of you tries to shout calming platitudes to the next, but none of you really believe that you’ll be saved. But then a helicopter swings in overhead and lowers a ring attached to a rope. They don’t have enough room for everyone, and you volunteer to stay in the water. But then the helicopter goes slowly toward a house on a hill, slow enough that you can follow and swim along close behind.
