I remain somewhat skeptical that near death experiences (NDE) involve a different plane of perception, but Pim van Lommel is far closer to convincing me than Proof of Heaven. Inspired by the transformative encounters described by his patients, the Dutch cardiologist has interviewed hundreds of people who have had NDEs and argues that they are “real”, cannot be dismissed as tricks of memory or the oxygen-deprived mind, and are suggestive of consciousness existing outside of the brain:
I grew up in an academic environment in which i had been taught that there was a reductionist and literalist explanation for everything, that it was obvious that consciousness was a product of a functioning brain. But the phenomenon of near death experiences raised a number of fundamental questions. I was unable to accept most of the answers to these questions because they seemed incomplete, incorrect, or unfounded.
