 that classical physics cannot explain. I mean, there's no electromagnetic theory that explains why we can have an NDE, right? People say, well, the brain is just hallucinating. Well, no, that's not true. For an NDE, the brain is actually usually shut completely down. There's plenty of examples of that. And so how can the brain that's completely shut down have this hallucinary phenomena? Because there's no brain there. So just realize that the mind is separate from the brain, and that's why we have this phenomenon.
