the more extreme transformations of consciousness associated with NDEs sometimes extend deep into the mystical realm, include veridical psi elements, and more commonly occur when the subjects are in fact physiologically closer to death (see IM, Chapter 6; Alexander, 2012; Holden, Greyson, & James, 2009; Owens, Cook [Kelly], & Stevenson, 1990; van Lommel, 2010, 2013).
