Popular term for the ability to travel outside the physical
body during sleep or trance, also known as etheric projection
or out-of-the-body traveling. Astral projection involves the
movement of the consciousness, often pictured as an astral
body or double, some distance away from the physical body.
There are numerous reports of this ability in popular psychic
literature as well as that of psychic research. For example, the
British scientist Dr. Robert Crookall collected hundreds of
cases from individuals in all walks of life.
