The Interview:

'DMT, the potent psychedelic found in ayahuasca dubbed ?The Spirit Molecule? is undeniably a bridge to a different reality. But the question remains, is that reality in our mind, or is that reality ontologically REAL. In other words, are the entities that you encounter in the DMT space ?other? or are they ?self?. And does that make a difference?

Dr. Andrew Gallimore and Carl Smith have been studying this phenomenon through revolutionary extended state DMT and we share both the stories and the research from what they have encountered. And for Dr. Gallimore, he believes that ?Interdimensional Citizenship Is Close At Hand?.
