I don't usually dream about the bike so much as I'm simply riding the bike in the dreams. For example, I might be dreaming about visiting strange architecturally interesting post-apocolyptic cities, and ride my bike as transportation. That said, when I was customizing my Nishiki, I'd dream that I was competing in a large bike race/tour, and my bike already had the upgrades/changes that I had yet to make. What's cool is that I got to watch myself ride, almost as if it was a movie. Because of this, in a strange way I can say my main ride is actually my 'dream bike', even though it's nothing fancy.
