Please help me identify a science fiction book series I read in the early 80s. The story starts with an American Indian that is given an injection so he remembers he's not just a member of a tribe, but a person on planet Earth that is controlled by a computer program that has taken over control of all humanity for its own supposed good. He escapes Earth along with a few others and they steal a ship parked out by Jupiter pursued by a type of cop which is actually the subconscious of this program. The ship travels to different planets where each person gets transformed into the inhabitants of that planet. Of course they succeed in bringing down this giant program thus freeing humanity to grow.
