this isnt really music related but its something similiar.
my dad sold a car that had an engine problem to my sisters boyfriend, and the car literally rev'd on it's own every 3 seconds like someone was wanting to race at a redlight.
I ALSO have a friend who drove a huge bronco with a loud motor in it who liked to rev his engine all the time anyways.
I fell asleep one night and had a dream that my friend was outside revving his engine outside trying to show off, and i woke up and my sisters boyfriend was leaving to go to work.
The sound of his revving engine triggered me to have a dream about my friend trying to show his truck off.
