Hmm. "Participants confirmed they had experienced sitting behind their physical body and looking at it." Sounds exactly like an out of body experience to me (and I've had them).
The point is that if the human brain can be fooled into projecting its awareness to another location, we simply cannot trust that the naturally occurring variant of this experience is mystical or spiritual in origin.
Because it's an optical illusion. They are seeing it so it seems real. Of course when people have out of body experiences, they arent wearing virtual reality goggles, and they often report having their eyes shut and "hovering" around their body when watching themselves, and the ability to control their ectoplasm movements and etc. To say it's reproducing an out of body experience is silly. A more correct way is to say the visual field overwhelmed participants understanding of bodily position. It's not like we have GPS receivers in our heads. Our brain believes what the eyes see. Of course you are experiencing sitting behind your body and looking at it, because you actually are! Your field of vision has been altered. Of course you are going to feel like you are in the place where your eyes are directed, because the human brain is designed to rely on visual perception and for most of us it's the predominant means of placing ourselves in the environment.
We also don't experience things like this often. Part of it is probably the novelty of the experience. After repeated exposure people would not notice the same effect. The physiological reactions they commented on are not surprising either.
People also react similarly if they are watching a horror movie. The brain reacts to visual stimuli. It's a mechanism to save us from potentially dangerous things. That is what is expected to happen. If you are in virtual reality goggles and you see what looks like someone stabbing you, you'll react. If people DIDN'T react, that would actually be something interesting.
Our visual system can also create the perception of moving, for example when people are at an IMAX film and become "sea sick". But people don't run out and say "we've discovered a revolutionary understanding of sea sickness!"
There are many other optical illusions that trick the senses. It's certainly a neat trick, but not something that deserves the attention people are giving it. All it proves is that the brain is easily tricked by optical illusion. Which we already know.
And it still doesn't explain ANYTHING about reported out of body experiences, because this setup is not something people encounter. You have to fool around with peoples brains to do that.
Actually, there is another study that I remember where people mildly electrically stimulated the frontal lobe, and participants
reported feelings of being out of their body. That one was far more "groundbreaking", and yet it wasn't all over the news.
It tells us a little bit about what possibly could be happening with the brain when people experience it naturally. However, I doubt that any amount of scientific study on this subject will convince people that there is no mystical origin.
