The dream body is the one with which you are most familiar. It has been called the astral body. It strikes you as being physical when you are in it, but you can do things with it that can't be done ordinarily. You can levitate, for example. As a rule, however, you do not go through walls with this body. This is the body you use for ordinary dreams. Levitation is possible with it but on a limited basis. When you enter a different dimension, the abilities of the body form change, and for all intents and purposes, it is a different body form -- which we will now call a mind form. It still seems physical in shape, but you can walk through physical matter with it.

There have indeed been civilizations upon your planet that understood as well as you, and without your kind of technology, the workings of the planets, the positioning of the stars -- people who even foresaw "later" global changes. They used a mental physics. There were men before you who brought back data quite as "scientific" and pertinent. There were those who understood the "origin" of your solar system far better than you. Some of these civilizations did not need spaceships. Instead, highly trained men combining the abilities of dream-art scientists and mental physicists cooperated at journeys not only through time but through space.

It is possible for you to project to a future event in which you will be involved and by an act that you make in the projection, alter the course that this future will take. Such an action would therefore appear to happen twice, once in your present and once in your future. But in the future, you would be the one whose course is altered from this traveling self from the past.
