When I died, there was no white light at the end of a tunnel, no gathering of the spirits of late friends and family members—it wasn’t even nothingness. Since my death and crossing into the after-realm, I’ve heard from others that it’s different for everyone, but at first we all experienced the same thing.
From what I could gather, there was one general consensus. Death is both painful and painless. Some spirits hypothesize that it’s the disconnection of the soul from the body, like snapping a rubber band so hard that it breaks. There was an immediate flash of crippling pain, and then a complete lack of feeling or body. Following that was some form of nausea, possibly the last physical feeling a soul experiences before arriving in the afterlife. I think it’s some form of spiritual whiplash; the shock from the pain of dying versus the immediate numbness almost creates its own feeling.
Scientists say that a brain can function up to a few minutes after the heart stops. I think that’s where the pain comes from, like some kind of echo. There’s also a hypothesis that says the brain releases every bit of DMT it has stored up in the brain, all at once. That would explain the following experience.
