This is part of a long sequence of dreams over the decades about the ruined city, and it is very large, in a wide plane. The rubble is new and some of the buildings are still red hot from a fire. This one is from somewhere around 1990.
I stand on the viewing platform. It is a long pathway, seeming made with wooden decking material for the floor and a metal fence on the side with a polished wooden hand rail. The scene is very dark and mostly black with a little red and yellow where there is heat and fires in the burned city below. The hand rail is a dark rich grained wood. The city stretches across the valley. On the other side are low hills. The valley runs from left to right. There is a small spot of bright light. I fly over, not stopped by the fence. It is a vertical shaft. There are rungs down the shaft. I fly down through the ground parallel to the shaft. At the base of the shaft are about half a dozen people. The control room is fully functional and ablaze with light. The people, good friends of mine, are leaving the room, via a hatch. The last leave just as I get there. I do not know where the hatch leads to. The room itself is about 30 feet across and circular.
