Are Psychedelic Aliens Real?

High dose N,N-dimethyltryptamine (DMT) experiences often include encounters with autonomous non-human beings. Some researchers propose these entities may possess an objective reality. They rely on an interface theory of perception to argue that such psychedelic states simply expand access to other parts of a wide network of conscious agents that are normally not perceptible. This hypothesis uses a mathematical framework based on Markov kernels to model transitions between states of experience during a trip. Critique remains strong, as these notions link perception and consciousness to mathematical abstractions that lack empirical support and do not clarify if these entities are actually independent.
