Astral Projection (or astral travel) is an esoteric interpretation of aspects of out-of-body experience perceived as unfolding in environments other than the everyday world, that assumes the existence of an astral body separate from the physical body and one or more astral plane to which it can travel. Astral Projection is experienced as being "out of the body". Unlike dreaming or near death experiences, Astral Projection may be practiced deliberately.   Wikipedia
