OK, I watched the video. And I understand why to any individual experiencing such a apparently highly mystical event, such as Pam experienced, may see that as a NDE and view it as she has.
Still, the point that struck me was around the 8 minute mark and the "unexplained" conclusion. Science does not know everything as I'm sure you know. Not knowing too much about any supposed NDE, I googled and came across this excellent article in "Scientific American". Please take the time to read all of it...it discusses NDE's from different well known people........

an extract from the article:
"Modern death requires irreversible loss of brain function. When the brain is starved of blood flow (ischemia) and oxygen (anoxia), the patient faints in a fraction of a minute and his or her electroencephalogram, or EEG, becomes isoelectric—in other words, flat. This implies that large-scale, spatially distributed electrical activity within the cortex, the outermost layer of the brain, has broken down. Like a town that loses power one neighborhood at a time, local regions of the brain go offline one after another. The mind, whose substrate is whichever neurons remain capable of generating electrical activity, does what it always does: it tells a story shaped by the person’s experience, memory and cultural expectations.
Given these power outages, this experience may produce the rather strange and idiosyncratic stories that make up the corpus of NDE reports. To the person undergoing it, the NDE is as real as anything the mind produces during normal waking. When the entire brain has shut down because of complete power loss, the mind is extinguished, along with consciousness. If and when oxygen and blood flow are restored, the brain boots up, and the narrative flow of experience resumes".
