Eli5: Chemically, what happens inside the brain as we begin to die?


I’m taking like, the last few moment’s. Is there a massive release of chemicals? If so, what are they and what do they do? If not, what do we know about what happens in the last few moments?

It has been said that the brain releases DMT when it’s dying which accounts for many of the hallucinations and past-life and religious experiences people report.

This is rumoured to be a sort of defence mechanism so that the mind could possible flash up a way to save yourself from death as a last resort.
