Bizarre dreams

I myself have these. My nightmares are generally work related, watching a cut of cars roll away while switching in the yard is the most common one, they always roll away just fast enough that I can't climb on and apply the hand brakes. Then there's the ones that involve hitting/running over stuff, derailing, or tearing lots of stuff up at a high rate of speed. I guess that's what happens when you operate a vehicle that weighs over 3,000 tons.
