The strongest formulation I can come up with is: "NDE studies also suggest that after physical death, mind and consciousness may continue in a transcendent level of reality that normally is not accessible to our senses and awareness."
However, nowhere in the article does the article's author offer a single/summary explanation of NDEs/OBEs, from what I saw.
I'm not really swayed either way, as I don't have sufficient data to make a good conclusion (and I need to do further research into it). I'm actually enjoying some of the comments here as they're providing good insight.
If someone insists on speaking with no tangible data, presenting conclusions that clash with occam's razor, then I will be less likely to listen to them going forward.
Once an author has weighed in with their personal interpretation, the only refutations available will be ad hominem. "I'm not calling you a liar, but I can't think of a way to end this sentence."
