>>6151556Dextromethorphan is a dissociative hallucinogen, an NMDA receptor antagonist and serotonin agonist like ketamine or PCP. It partially cuts your brain off from your nervous system via the NDMA antagonism while the serotonin release causes hallucinations and the result is a complete loss of sense of self and identity. The experience I got from it was a sense that I had seen ultimate reality and that waking life is just a kind of Matrix or illusion, and that there is only one consciousness in this whole universe.
