This is an interesting and unexpected question. Of what I remember equipment never appears in my dreams. It probably does from time to time, though, but that's an assumption.
Do you past equipment appear in your dreams?
I see recurring dreams about an Audio Innovations tube amp I used to have. In the dream I suddenly remember I need to get new tubes, after then everything becomes difficult.
That amp was great, a bargain. It broke, of course, and somehow my dad got rid of it, took it to a crap metal shop maybe.
