Every time I feel I'm about to separate from my body, a wave of intense fear overwhelms me. The ivory-tower conclusions held by many researchers are completely archaic and meaningless in the light of a single personal experience. Many people desperately attempt to fit this unique state of consciousness into their accepted model of reality. These sounds and sensations normally dissipate after separation is complete.
Many people report a physical-like environment.
This environment does not necessarily correspond to their immediate physical environment. It gives us the ability to obtain firsthand knowledge of our existence. Most people report a higher-energy duplicate of their physical body. The form we experience is a direct result of our expectations and beliefs. In general, most people will see themselves as they appear in the physical world.
