Maybe it's from spending too much time on TB, but I have bass gear dreams all the time. It is usually in the context of setting up for a gig or rehearsal in the dream. Just the other night I had a dream that I had these two cabs that were about 5" tall, 24" wide, and pretty deep. They made this tiny stack that pumped tons of low end. I told my wife that I mostly dream about bass gear and playing bass and she rolled her eyes.
