Explosion . . .

So I'm working at an office and I think my boss is leaving or something, it's nighttime and things are normal.  I get off early for some reason and like, I come back to work apparently I work nights, it's nighttime again and a train is passing by the building and before it gets there it explodes like crazy.  I'm amazed and all but just really glad to get off work early.  I am talking to someone in the dream about it on the phone I think.  Weird.
