Yeah, I did think that, but it happened. I was there. I heard it. So I couldn't totally deny it. I didn't know what to make of it. I thought it can't be what it really seems to be on the surface. It's got to be something else. So I started doing research on all the possible things that could have been going on. Was blood oxygen falling? Were there drugs given to the patient?

Was she taking drugs that made her hallucinate? And all sorts of things like that. And the more we studied these variables, the more unexplained the near-death experience seemed to be.

The first thing that occurred to me was lack of oxygen, because no matter how you come close to death, that's one of the final things that happens to everybody. So we had several people actually measured the oxygen content in people's bloods. Michael Sabom did this in the U.S. Pim van Lommel did it in the Netherlands.

And they reported consistently that people who have near-death experiences have better oxygen supply than people who do don't. I have to put the caveat here that they're measuring oxygen in the blood. They draw blood and measure oxygen. They're not measuring from the brain itself. So it's conceivable that there may be some local oxygen deprivation somewhere in the brain.

I don't know why that would happen. We have no explanation for why that might happen. but another idea was drugs given to patients, and again, that turned out to be not the case. People have looked at electrical activity in different parts of the brain,

There was a theory that a particular part of the brain in the temporal parietal area, which makes us tell where we are in space, was going off somehow when you're getting close to death. And that makes you feel you're leaving your body. But people who have that experience, they actually stimulate, electrically stimulate that part of the brain.

and they have a sense of losing control of their bodies, and they report things like, I feel like I'm falling off the table, or I feel like my legs are getting shorter. Sometimes they report seeing a double of themselves, but they never report out-of-body experience that near-death experiences do, which is being outside the body, looking back at their physical body lying on the table.
