Food really hasn't changed that much I don't think, but the clothing trends have. Generally you could get away with wearing casual clothes in 1993 from 2004 and vice versa, but I guess some things just wouldn't fit in, especially women clothing trends from what I've seen. The guy stuff is still all the same in most respects.
I think the dreams are just that, dreams. But anything is possible, otherwise I wouldn't even be here.
From the historic events that I have seen (I'm doing history topics in school for this very purpose) there have been no differences in history.
