It was an interesting dream.
“One scene involved an outdoor conveyer belt about 12 feet above the ground carrying contruction refuse – boards with old nails, etc. But there was no solid floor on the conveyer belt – you had to either sit tight on the debris or if you wanted to move faster, you’d have to carefully walk without falling through the pieces. It wasn’t high enough to kill you but you’d get hurt if you fell, or if debris fell down with you, you’d REALLY get hurt. “
in retrospect is a “the map and the territory are different but also the same”.
