Whereas humans in their physical bodies experiencing incarnation in the physical world are in space/time or outer planes, the non-physical portion of the third-density experience is in time/space, or inner planes.
Also called invisible or metaphysical planes, or time/space dimensions; including various planes such as astral planes and devachanic planes that are inhabited by entities who range from thought-forms in the lower extremities to enlightened beings and those whose vibrations are even more close to the primal distortions of love/light in the upper; there are also discarnate entities who are in between incarnations or who simply do not collect about their spirit/mind complexes a chemical body.
The inner planes are also experienced in between incarnations in the review and healing of the previous incarnation and the planning of the coming incarnation. They are also entered in the dreaming state and in other modes of non-ordinary consciousness.
