Thank you tom,
happy to meet another psychonaut!
the science around it would be to admit we live in a simulation (DMT gives this insight). And the 5meo/god feeling would be a link (through the matrix) to the main AI that organize our reality.
That's the model I would use first. Unfortunately very few brain scientists work on the subject. check Dr Carhart Harris. I believe he just started his research.
you can download this game I wrote on the influence of 5meo after years of practice:

the key is to mix it with harmaline (don't do it before reading)
