Aren't you guys all about evidence and proof? If NDE's are nothing more than "hallucinations" then I'm pretty sure that there is scientific test data to prove this.
So where is it?
Thy wish is my command, master.

Quote:A 2005 study found that out-of-body experiences can be artificially triggered by stimulating the right temporoparietal junction in the brain, suggesting that confusion regarding sensory information can radically alter how one experiences one's body.
A variety of explanations might also account for reports by those dying of meeting the deceased. Parkinson's disease patients, for example, have reported visions of ghosts, even monsters. The explanation? Parkinson's involves abnormal functioning of dopamine, a neurotransmitter that can evoke hallucinations. And when it comes to the common experience of reliving moments from one's life, one culprit might be the locus coeruleus, a midbrain region that releases noradrenaline, a stress hormone one would expect to be released in high levels during trauma. The locus coeruleus is highly connected with brain regions that mediate emotion and memory, such as the amygdala and hypothalamus.
In addition, research now shows that a number of medicinal and recreational drugs can mirror the euphoria often felt in near-death experiences, such as the anesthetic ketamine, which can also trigger out-of-body experiences and hallucinations. Ketamine affects the brain's opioid system, which can naturally become active even without drugs when animals are under attack, suggesting trauma might set off this aspect of near-death experiences, Mobbs explains.
Finally, one of the most famous aspects of near-death hallucinations is moving through a tunnel toward a bright light. Although the specific causes of this part of near-death experiences remain unclear, tunnel vision can occur when blood and oxygen flow is depleted to the eye, as can happen with the extreme fear and oxygen loss that are both common to dying.
Altogether, scientific evidence suggests that all features of the near-death experience have some basis in normal brain function gone awry.
