2.  People near death, and sometimes those who have been resuscitated after dying, report common experiences of peacefulness followed by separation from the body. At first there is darkness then seeing a source of light and moving into the light, sometimes through a tunnel. At this point, many turn or are turned to move back into the body. Sometimes they see family and friends, and other times a "presence," who all advise that it is not yet the time for the person to pass over. Other times there may be a review of the lifetime and a decision made by the person to return to complete unfinished business. It is nearly always a very positive and transformative experience, giving the person a much greater appreciation of life.
