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.
