Why do our brains release these ‘chemicals’ that make us not afraid in our last moments?

977 views

I’ve heard of people with near death experiences having these calm, soothing experiences. It’s lovely that our brains do this for us.
I know there’s a natural selection, those with the best characteristics continued, and those who didn’t have the qualities to survive would pass away. But everyone dies in the end. What made it so that all brains release those chemicals to ease our last moments?

Doesn’t the brain have a certain amount of DMT (Dimethyltryptamine) it releases? Basically sending you off on a ‘trip’?

*Commonly described features of the DMT experience include a feeling of transcending one’s body and entering into an alternative ‘realm’*
