I remember scenes of saving someone with two others from a burning houseboat on a lake.
The setting was the end of the world caused by pollution. In the survival group I was with, one guy once flew over waterways and dumped leftover Artex into it. I partly blamed him for the end of the world.
I tried to go back into the dream later for more details of the story. All I got was a rising waning gibbous moon that put the time a couple of hours after sunset.
