I found your dream interesting as the Russian spacecraft Phobos Grunt is about to drop out of its failed orbit on or around Jan 16th and could possibly be over the US on re-entry. The thing is full of Hydrazine and other toxic materials and could produce a large nuclear type explosion under the right conditions in the atmosphere. This may coincide with a couple of dreams I have recently had concerning a cell phone or the electronics in it 'frying' making it useless and another where everyone had to walk and cars, trucks, big rigs were all stalled and only an old 40's type vehicle was able to drive away as it is not dependent on electronics.  We shall see.
