I actually think it would make a viable business if there was some integrated astrology/fortune telling aside of the dream. Horoscopes are huge businesses in Asia. (Of course, you'd have to know how to produce horoscopes)
It's easy. Pull a bunch of random, vague shit out of your ass. I bet someone could write a wicked horoscope generator, kinda like the postmodern essay generators: http://www.elsewhere.org/pomo/
