The Phasing Model, which was defined by Robert Monroe, holds the belief that it is impossible to actually leave your body in the truest sense of the word, and that the astral planes and the physical world are merely points on the long spectrum of consciousness. When a person projects, they actually "phase" into another area of consciousness and the locales it contains. This can be likened to tuning a radio to another station. One of the initial signposts representing a phase shift away from physical reality has been labeled the state of focus 10 (mind awake/body asleep). This viewpoint can be seen as a logical progression of the philosophy that external reality is actually an internally created state

Astral Projection - The traveler finds him- or herself in an apparently real domain, analogous to the "other worlds" experienced by traditional peoples, which have no parallel to any physical setting or to consensus reality, described by New Agers and occultists as the astral plane or "the astral". Environments here may range from populated to unpopulated, artificial to natural to completely abstract environments and from beautific to horrific. Here, normal physical laws often do not apply and humans can often, for example, float or fly. Quality of physical detail ranges from crude, non-detailed and depressing to bright, vivid and fascinating as detailed, among other writers, by Robert Bruce in his Astral Dynamics.
