My personal oppinion:

The logic is hidden in the chaos, like as if it were incripted. Sometimes, not always, you can understand and interpret a dream. Like they say in American McGee's Alice:
Sometimes a mirror exposes more reality than the object it reflects.[/b]
I know it's a video game, but I find a lot of truth in that quote. When I dream it's as if the whole world is filled with strange metaphores that can only be understood through the feeling of emotion. Then, when I wake up, I add it all together with whatever's going on in my current life and it makes sense.

I say: there's sense in nonsense.
