Read the passage from "The Book of Martha.”

"Maybe. But I really mean that somehow people should spend a lot of their energy in their dreams. They would have their own personal best of all possible worlds during their dreams. The dreams should be much more realistic and intense than most dreams are now. Whatever people love to do most, they should dream about doing it, and the dreams should change to keep up with their individual interests. Whatever grabs their attention, whatever they desire, they can have it in their sleep. In fact, they can't avoid having it. Nothing should be able to keep the dreams away—not drugs, not surgery, not anything. And the dreams should satisfy much more deeply, more thoroughly, than reality can. I mean, the satisfaction should be in the dreaming, not in trying to make the dream real."

God smiled. "Why?"

"I want them to have the only possible utopia." Martha thought for a moment. "Each person will have a private, perfect utopia every night—or an imperfect one. If they crave conflict and struggle, they get that. If they want peace and love, they get that. Whatever they want or need comes to them. I think if people go to a . . . well, a private heaven every night, it might take the edge off their willingness to spend their waking hours trying to dominate or destroy one another." She hesitated. "Won't it?"
