On Valentine's Day, 1993, Caveh Zahedi decided to ingest 5 grams (a very large dose) of hallucinogenic mushrooms. For the first time in his mushroom-taking history, he had an experience of "divine possession," in which he felt that a divine being took possession of his body and spoke through him, in a voice that was not his, and with knowledge that he himself did not possess. He later tried several times to repeat the experience. I WAS POSSESSED BY GOD is the documentary record of one such attempt.
