With near-death experiences, shared-death experiences, past life regression, evidence for reincarnation, and the kind of visitations discussed in this article, there is just too much smoke indicating life after physical death for there to be no fire. Even if it cannot be proven in a stricly scientific sense, something is going on in a dimension beyond our physical existence. Should it be called "supernatural"? Maybe it's just as "natural" as our physical universe. The only difference is that we don't fully understand it, so we put sort of a spooky label on it. It is surely worthy of scientific inquiry, and some research has been done, but most scientists ridicule the idea of that other dimension and call it woo. Hopefully at some point that will change.
