To assess whether consciousness exists independently of the human brain, people such as Sam Parnia are doing experiments in which images - or electronic devices with images - are placed in locations near the ceiling in hospital rooms where people might be expected to have near death experiences. The images are supposedly in put in room locations that are inaccessible to both patients and hospital staff, but might be visible to a patient having an out of body experience. If there ever is a reported instance in which a patient in such an experiment reports having an NDE and identifies the image correctly, would this one example be sufficient to claim beyond a reasonable doubt that consciousness exists independently of the human brain? What are other explanations for such a reported instance?
