Sorry, I'm not sure if I'm rambling or answering your question. But I'd say on the point of soul was not to get into airy fairy theories on our consciousness. I'm just saying, I see the body, the ego (which may even disguise itself as 'you'), and 'me' (whatever that is, spark, soul, life force) as different.
They say when you die DMT is dumped in your brain which is why a lot of people with near death experiences see things. When you breakthrough, you are having an out of body experience in a way. My theory, admittedly with 0 proof, is that once your body dies and there is no sensory interruption; you will ascend to the next plane.
Right now if you do it you feel like you're ascending, almost dying and going to heaven or something...but you never do. I think when the body no longer is connected, there is nothing to hold you back.
I know, this sounds all nuts LOL
