Any theories abotu dreasm out there.

My pet theory abotu dreams is that they don't happen in events, but in realms. There are realms that only you have, some that you and a few other people have, some that many people have and many that everybody has. Some realms even exist which can only be found through meditation, lucid dreaming, amazing luck or by accident that have been pulled far away from humanity. Each realm would have a theme (emotion, idea expressed, important character), so to speak, and other things like particular events or such.
