Multi-sensory group hallucinations are commonly disparaged as a potential naturalistic explanation for the New Testament's accounts of Jesus' post-mortem appearances. However, group hypnotism is a widespread and well documented practice capable of making otherwise sober individuals sincerely behave and profess to believe that they are experiencing virtually anything imaginable. Have any scholars considered whether the "appearences", especially as recorded in 1 Cor 15, could be due to someone like Peter guiding himself and others through such ecstatic experiences?

1 Corinthians also relates the practice of glossolalia, speaking in tongues. The modern practice appears strikingly similar to hypnotism, with features like being spurred by on by a leader, and I find especially striking the frequent use of touch as a trigger to spread the behavior between individuals. If ancient Christians practiced hypnotism to generate their experiences, did it survive into this modern ritual?
