Near-death experience or lucid dream? Researchers solve the mystery

In a new exercise by a California organization that studies lucid dreaming, volunteers have been conditioned to dream near-death experiences, including the classic scenario of flying toward a light at the end of a tunnel. The researchers say their experiment demonstrates that these heavenly visions must be products of the human mind rather than supernatural phenomena.
In the sleep experiment at the Out-Of-Body Experience Research Center in Los Angeles, four groups of 10 to 20 volunteers were trained to perform a series of mental steps upon awakening during the night that might lead them to have out-of-body experiences. If able to "separate" from their bodies, they were then conditioned to try dreaming about floating through a tunnel toward a bright light. Eighteen of the volunteers said they were able to dream such an experience.
"Some of the test subjects not only succeeded in reproducing the out-of-body flight through a tunnel, but also enjoyed the ecstasy typical of the experience, and even flew all the way to the light and met their deceased relatives there," center leader Michael Raduga stated in a press release about the work, which has not been published in a peer-reviewed journal.
More than 8 million Americans have had a near-death experience, and they most often occur during states of anesthesia-induced sleep, according to the center. Prior work by neurologists, including Kevin Nelson of the University of Kentucky, suggests that NDEs are indeed generated by the same brain mechanisms that cause lucid dreams. Nelson's research shows that both types of experiences arise when part of the brain called the dorsolateral prefrontal region — our "logical center," which is usually active only when we're awake — becomes active during REM sleep, allowing extremely vivid dreams that seem to be happening in real life. He calls the transitional state between dreaming and wakefulness a "borderland of consciousness" and believes it is in this mixed state that lucid dreams and NDEs occur.
With Nelson's research in mind, Raduga designed his experiment to determine if volunteers could be coached to dream up NDEs when in the transitional phase between sleep and waking. This would demonstrate that reports of NDEs, which are commonly cited as proof of the supernatural, really are just lucid dreams.
Volunteers who successfully generated NDEs described their experiences for the researchers. One participant, identified by the center asNadezhda S., stated: "I was able to leave my body after a couple of tries. Now that I was out of my body, I wanted to see the tunnel and it immediately appeared in front of me … Once I flew to the end of that tunnel … I saw my deceased husband there in the spirit. We spoke for several minutes. His words, touch, bearing, and feelings were real, just like during his life. Later on, when I felt it was time to leave, I went up to the tunnel, jumped and gently landed in my body."
Nelson said conclusions from the research should be "cautiously drawn" until the findings pass the peer-review process, but they are nonetheless well-aligned with prior research on NDEs. "Lucid dreaming can be conditioned and bears an uncanny similarity to near-death," Nelson told Life's Little Mysteries. "Indeed, Raduga's study demonstrates the similarity of near-death and lucid dreaming. Evidence from many sources converges to support that lucid dreaming and near-death use similar brain mechanisms but in different circumstances."
The research may have implications for those who believe in the afterlife. "NDE, as the most trusted reason for believe in life after life, may be just the result of spontaneous and hyper-realistic lucid dreams, induced by narcosis or brain damage during dying," Raduga wrote in an email. "This means that NDEs aren't evidence of life after life."

The only conclusion that can be drawn from this research is that people can lucid dream the things that happen during a near death experience. It has absolutely no implication for whether these experiences during dying are real or not. If I manage to lucid dream about a time I ate steak for dinner does that mean that it didn't happen and I was actually lucid dreaming?
This research like many others cannot disprove the existence of near death experiences. There are many cases where near death experiences are reported even when the heart or brain have ceased to function (sometimes for significant amounts of time). Also, there are many cases where unknown data reported by NDE experiencer e.g. surgical equipment or converstions of medical staff have been verified. Researches such as these are biased with skepticism and assumptions right from the start.
The experimenter is presenting false equivalents. How many of the subjects were under anesthesia, in cardiac arrest or had no brain activity. It seems likely to me that the results were a result of a hypnotic suggestion given to a fully subject with a functional brain.
I find it funny how these people blindly claim to NDE and to spirits despite studies showing otherwise.
Although I'm sure that NDEs arise from hyper-reactive brain states this experiment shows nothing.
I could train some volunteers who have had no experience of space-travel to lucid-dream a journey through space. I imagine that many of the volunteers would successfully experience the space-journeys. This does not prove that space-travel only exists in the mind...
I have experienced dark tunnel experience and most fearful nightmares many times in my youth.Later I developed temporal lobe epilepsy and living with it for the rest of my life.
i freakin astral projected! it was so freaky!! just say if you want the deatils(reply)
ok, but how about those who have the experience while the heart has stopped?
There is some interesting research (Pim Van Lommel) that suggests that consciousness resides in a remote "place," and that we merely tune into it with our brain. If this is true, then this research certainly does not prove anything about an afterlife or the continuation of consciousness following physical death. Thought may not be produced by the brain. What we know about this subject would not cover the head of a pin.
I dont see how people can control their dreams
i could
Is there eny real proof of the spirit world , and if so , is there an existence of life for these lost souls , Do they live there life like ours , or are they trapped in there own existence ...
If it's all dreams how do we have all the same dream???
I think this article has truth to it, i've been practicing lucid dreaming myself, and this makes perfect sense.
I don't believe in an afterlife, but I don't think "proving" that NDEs are just lucid dreams "disproves" an afterlife. Religion and science are separate philosophies and should be kept so.
Natalie Wolchover, how pathetic to claim "solved" prior to peer review! Have you no scientific scruples?
Near death experiences are real spiritual experiences. 35 years of research have proven it. Science cannot explain it.
Wrong. Brain chemicals brain chemicals brain chemicals!
No chemical, no chemica, no chemical! 0;)))))))
