Studies show that there are a significant number of people who report unique experiences when in a near death state. Common components of these experiences as first detailed by Dr. Raymond Moody include ineffability (words don't exist to fully communicate the nature of the experience), the sensation of being pulled through a dark space/tunnel, observing one's body from a place separate from the body, meeting other spiritual beings (often deceased loved ones), communicating telepathically with these beings, encountering a bright light and meeting beings of light, experiencing a life review (sometimes experiencing it from the perspective of others the NDEr had interacted with), seeing extraordinary sights, experiencing a love that is beyond anything imaginable in this world, and resistance to returning to the physical body. Not all these are present in an NDE but they are observable commonalities.
