An umbilical cord silver in appearance that is attached between the astral body and the physical body that has been reported as being observed by persons during out-of-body experiences (OBEs). In pioneer research of astral body projection this phenomena seemed common; however, later data tend to show it to be rare. British parapsychologist Celia Green reported that 3.5 percent of her subjects reported seeing the cord, while Australian psychical researcher Peter Picknell reported just 2 percent of his subjects observed it.
