Mixing a band on a train that never stops

Last night I dreamed I was mixing a live band in a moving train car. The kick drum was the rail rhythm, the vocal kept phasing in and out of tunnel static, and every time I reached for a fader the train hit a switch and reset the whole board. I wasn't finding the mix, I was just following it. Woke up with my shoulders tense like I'd actually been riding that thing all night.
