I dreamt of a gigantic spacecraft holding several million people traveling to a new earth. The trip took thousands of earth-years and hundreds of generations. The life on the spacecraft was hard even though everyone was united by the dream of the new earth. Different ideas about the new life sprung up over time, and their differences led to strife. By and by, veritable wars took place between adherents of different ideas, which became very like religions. The spacecraft was occasionally in danger of being demolished by internecine conflict. When it finally reached the new planet, which turned out to be almost exactly like the old earth, not many people wanted to leave the orbiting spacecraft. Deeply divided, they preferred the security of the world they knew so well. Only a few hundred of them landed on new earth in search of a new beginning. They lived by hunting and gathering. When I woke up, I was delighted by the dream, but I immediately noticed that it was like a movie or even a novel rather than a direct experience. I was not among the colonists of new earth, that is. But an observer, I had no emotional attachment to anything I had witnessed.
