Well, my view on NDE's is that you are
a) in shock - distorting what you deem plausible
b) the chemicals in your blood are ceasing to be regulated - certain highs come about as a result
c) you aren't actually dead until cells for the most part systemically turn necrotic - so NDEs are just EXTREME experiences given credibility cuz its "the closest you can get" but that is an assumption, not accurate Your skin is constantly dying, it form the upper layer you touch, then it flakes off. In a way the body becomes like that skin, and flakes away, to get digested by lil bugs and stuff just like dustmites live on our skin right now and eat dust. Its shocking that an entire body, that was once so solid,.essentially becomes transient... Especially since that spark of life is so precious and not entirely understood. I can't say what is true about death
I can only surmise that the familiarities of biological existence become an impossibility
All those lovely chemical reactions arent churning anymore
I'd imagine that everything gets "heavy" and then settles...
Before it does so, I imagine it gets highly imbalanced, and reactive, creating some NDE type stuff. That said, I'm not totally morose about death.
There is a very very narrow possibility that the universe itself is constructed in such a perculiar way that just like it supports initial life that it may also support the incredibly unlikely, such as some form of continued utilitty of your original spark.
I can only wildly speculate on that though...
Like, say... instead of the big bang, there was a "big injection", and outside of the physics we know exists a cucoon of physics that isn't the same as our physical universe and is inaccessible. Say, in that cucoon chemical processes don't require physical matter, but exist as echoes, or shifting forms. Maybe you'd slip into some other sphere of existance, just like an echo. And by some crazy fluke, it holds form.
I sort of believe in a "big injection" kind of thing, since imo the world is unlikely to begin entirely uniform, and so therefore, I feel its plausible there is a double image or weirdness with the big bang we haven't seen yet.
If you ever watched the movie source code, the main character proceeds to live in an alternate dimension.
In my view, you would not enter anything so elaborate, but maybe just sort of float like a jelly fish, in some chemical after image in an alternate version of physics.
I wouldn't confuse that with any substantial idea of afterlife though.
Lifes a bit of a miracle, if death was too, it'd be neat, but yeah...
