Dreaming in Reverse

Yesterday morning, I awoke from a dream that's been stuck in my head since then. I was a passenger in a minivan along with my current work supervisor and the lady who served as rehearsal accompanist for the St. Louis Symphony Chorus during the years I sang with that group. The pianist was at the wheel of the car and for some reason, she was driving entirely in reverse, at full speed, maneuvering around corners and whatnot. It was kind of a thrill ride, actually, and I felt a sense of danger. I'm not asking what such a dream might signify. Most likely, it signifies nothing. But it sure was weird.
