Because I've never heard of someone encountering such a thing while in a near death state, to this day I've just assumed it was something my brain made up in order to bring me back via shock.
It's definitely traumatized me though. I felt this odd feeling of rejection for the next few days, I was super depressed but after using some rationalization I allowed myself to recover.
Though to this day I wonder why my brain would make such an image. Most people see God, Heaven, Hell, or perhaps demons when in near death, so why would mine create such an odd scenario?
It makes me wonder what my fate will be when I die; which is why I've pursued eternal life. I hope that technology will advance for me to live forever.
