I am so glad to see questions like this.
My vote, even after being deeply touched by the molecule, is still overwhelmingly YES: the world is real and not a personal hallucination.
I can see how DMT makes one aware of different worlds and consciousnesses. But it does not yet convince me that realty is fake, or than nothing exists, or any number of parallel universe or matrix theories.
These theories cannot be easily disproven, so....Really it just comes down to this: does believing the world is a hallucination have any benefits or effects for me? To me, the answer is no.
I Currently believe that I am a created being in a universe that someone else controls (God). I also used to believe that psychedelics could only reveal thoughts within ones head, but now I believe DMT can expose you to spiritual entities... 0.o
I will read over the link in your post. Happy travels to you!
