I have to wonder if we'd start getting bored with them because they're now our "real lives."
And it seems my dreams can take whatever direction I really want. Or whatever my subconscious wants. Some would argue that our actual lives can be directed however we really want, too. I disagree. My dreams seem to have much more color and life, passion, feeling. And I don't seem to break a sweat.
Generally, my dreams produce some kind of peace. Then I wake up to start real life. All over again.
