I dreamed I lived in an enormous city, a very old city, and had a little motorbike. The drivers in the city could turn on a dime; no one followed traffic rules. There was a war. I lived in a tiny room crowded with people including Moomin and my friend Debbie. At one point I barely escaped an avalanche - on my motorbike. Another, I was with some people of my neighborhood when we discovered that one of the storm sewers opened up into an underground palace. Me and another guy crawled through the shallow water - it had not rained in years - to see the caves open up into a blaze of light and marble. It seemed inhuman. In that line of shops and little houses there were four or five openings into the archeological site. We came up to the street to the gathered crowds, raving, explaining what we'd seen. People were afraid to go in, but the news spread out into the city.
As I went to a little shop nearby I got word that my superiors were going to destroy it to preserve it for future generations. I was a time traveller and not in my time. They would send a British bomber jet to those coordinates, drop some bombs to seal the entrance, because this world's time's archeology wasn't advanced enough to properly excavate the site.
I had to get my family out, but I also warned the other people in the shops and houses above the other entrances, though I couldn't explain how I knew what was going to happen. This blew my cover and made it clear I was a spy. No one accused me, because they respected that I was saving their lives, but there was a general drawing-away that made me sad. One of the family houses had a family who were cruel to a girl on crutches, the girl I wanted to marry, and I knew if I warned them, they'd leave her prisoner to die. So instead I made some excuse, trying to get her out of there, and left her abusive family to the bombs.
