I had a dream some time ago that I was riding the train that is running out of control. It has been derailed and smashing some cars along the ride. Then, it went to the highway still out of control. Strangely, the people in the train seems very calm and doing normal things (I have experienced with MARTA train not moving between stops for a while). At the end of the wild ride at the highway near the underpass bridge, the train finally stop without any mess. We finally got out of the train without any injuries and/or panic.
