By him saying "Bought and sold like property" I think he is saying that love comes and goes all too quickly these days. It just seems to be passed on to one another without the full appreciation like when it was pure. Also when he makes a reference to "looking backward," I think that he is talking about having their pasts come back to the present. So they aren't litterally looking backwards but they are thinking of the past. When he starts to talking about the end, I think that he is talking about how no matter what someone says, when the end come, it's done. Nothing will ever be the same no matter how hard you try. That would lead to the dreams "scattering" and "falling like rain" there is no organizatoin to rain, it just falls and you can't gather it back up. When it falls, it's gone.
