It is technically supposed to be near-death, but I have no other words to describe it so I use that term. "Timeline jumping" is a fad on reddit, so is "reality shifting" and "glitch in the matrix," but the closest I've come to finding something that describes what I did is the concept of time being simultaneous and there's actually just "possibility/probability vortexes" and I just directed my consciousness to a different vortex. That comes from the Law of One channelings (free at www.lawofone.info/s/1.) They also describe densities that we go through during our consciousness's evolution, which I described as "layers" when I was going up then back down them in my NDE. But yeah, my old body wasn't viable anymore, there was no going back to that timeline or vortex or whatever
