Like I said, I really don't expect to find the "true" answer to all this. My point was basically that our current scientific knowledge may not be able to explain everything. We can observe the brain and see what's happening, but the brain and the mind is still a big mystery in science (as far as I know, it's been so many years when I read about this stuff). And I believe you immediately, without checking first, when you say that electricity can provoke such experience. In my youth I was also interested in brain wave states and how to "manipulate" them with binaural beats, for example. So it seems plausible to me that electricity can provoke a change in the current brain wave state, and thus induce OOBE like experiences. I think there was even a Kickstarter campaign or something for a device which was supposed to aid in experiencing lucid dreams. It also worked by inducing some electricity, as far as I remember.
