In the case of a collective dream, yes. Basically - if it's a personal dream that others aren't sharing in then it's personal growth and change. When you change the scope to a collective dream, you change the context of the meaning to fit that scope.

Think of it like a large number of people subconsciously crying out for help, using the same basic set of images. Since it's about the world and society and not each individual person there's a chance that the dream would be shared by those in the same community, sharing the same perspective. ((I say "there's a chance", because as I said earlier - the 'collective subconscious' idea is a theory that can't really be proven or disproved. It is, however, the best fit for this particular scenario...))
