> The final section explores whether NDE and DMT experiences have a sufficient degree of phenomenological similarity to justify a causal role for DMT in the production of NDEs and concludes that such similarity is lacking.
From me reading the abstract, doesn't seem like it. But I haven't read the paper, and don't know what "phenomenological similarity" is either.
It would be cool to think that we could trick our brains to do that on demand, without having to experience a near death situation!
I can already imagine the headlines, "Shamans hate him! Learn this one trick how you can too..."
Probably just in case the thing that would have made us die doesn't actually make us die so we don't fully process the horrifically traumatic thing that caused us to almost die
When your brain dies, depending on what the issue is, your brain no longer works under normal circumstances.
If your heart stops, oxygen is going down, it could just mean that your brain regularitory features stop working as designed and it's firering more random.
More random / lsd / drugs can give you weird effects. Optical, sensorical etc. illusions.
