I had a pretty epic one near the beginning of this year that was similar to yours in detail, such as the people in it I know in waking life but the scenery was different. This didn't make sense until in retrospect I realized my surroundings were distinctly Russian, in a very dismal grey are of a city. I saw in slow mo a meteor striking the ground while i was looking for the asteroid passing by at the time, resulting in an explosion and a mushroom cloud, and then became involved in the ensuing chaos.

Then I woke up, couldn't sleep so I ended up on GLP and it turns out I was dreaming this DURING the "meteor" explosion (or whatever it may have been) over Chelyabinsk. The difference between dream and "reality" was the actual doom factor. So, I bump this thread for you.
