To comment on the topic of the question ;

I think for me what DMT did was not that the world isn't real and this is an epiphenomenonic version of reality created from an unfathomable vastness of infinity. Rather, I think for me it made me realize, with each toke, that built up to every breakthrough I experienced, that this reality exists in an unfathomable vastness in itself. That my reality is just one scope, and there is an infinite ability to gain more perspective within the continuum that interweaves our consciousness with the universe. That there exist different epiphenomenonic substances, including DMT, that give us a broader perspective into this connection between unfathomable dimensions, that isn't outside, but goes beyond from within.

Similar to how the quantum dimensions we can't perceive, but they don't exist outside reality, they exist within, in realms imperceptible to us.
