Peter Boghossian and Andrew Gallimore explore the profound effects of DMT (Dimethyltryptamine) on consciousness. They discuss DMT's production of robustly coherent environments and "non-adaptable perceptions" as a casual explanation of DMT realms. Andrew also shares insights into DMT's entities and intelligences and they devise a test for evaluating the ontological status of DMT realms. Andrew Gallimore is a neurobiologist, chemist, pharmacologist, and writer interested in the relationship between psychedelic drugs, the brain, consciousness, and the structure of reality. He is based in Tokyo, Japan. Watch this episode on YouTube.
