Several months ago I had this dream. I was on a streetcar in Toronto. The streets seemed dark and dirty, it all just seemed like something was wrong. I got off the streetcar and walked a short distance to a corner. At the corner I turned right and as i turned, I saw rubble everywhere. there were still tall bldgs but they were destroyed. there were mounds of rubble. I kept looking around trying to see something I recognized, anything, street sign or bus or street car, but there was only rubble.
If this is a dream about a future event, it could be from a huge earthquake or some kind of missle or bomb attack.
