Introduction
Dr. Eben Alexander and Graham Nicholls had a good discussion about OBE's and NDEs that can serve as an introduction to the subject.
Graham Nicholls has probably had more verified evidential OBEs than anyone. And Dr. Alexander is a neurosurgeon with a very interesting overview of the subject, which he discusses in his book Proof of Heaven.
Since Dr. Alexander describes the evidential aspects of his NDE in this video, we have included in the database below, as well as some of Graham's reports.
