I cannot resist, I've done meditation with never performing the out of body experience and I've read about it in great detail. I would still think the possibility of it all being a hallucination and even if performed with thinking it was definitely real. Hallucinations can be so real that they're impossible to disprove. Consciousness might not even be real in the sense that most people think about it as because reality tends to be deterministic with the impossibility to prove otherwise.
