Hello A Deep Meditation,
Welcome to the Nexus. I'm so glad you signed up for membership and submitted an Introduction Essay. I love learning about new members here.
I hope you have had an opportunity to take a good look around - there are sub-forum headings for almost all those things you said had your interest.

I wasn't quite clear from your essay if you had actually tried DMT freebase or ayahuasca yet.
Also, what other entheogens have you tried?
Anything else you'd be willing to share such as focus of career or education or hobbies, etc. would help us to get to know you a bit better. I do hope you choose to actively participate.
Again, welcome to the Nexus.
"But even if nothing lasts and everything is lost, there is still the intrinsic value of the moment. The present moment, ultimately, is more than enough, a gift of grace and unfathomable value, which our friend and lover death paints in stark relief."-Rick Doblin, Ph.D. MAPS President, MAPS Bulletin Vol. XX, No. 1, pg. 2Hyperspace LOVES YOU
