"Well, what you've been calling out of body experience and/or near death experience, tunnel of light, etc. is simply a 17 billion year old consciousness transfer mechanism I created after my first experiments with long range matter transfer of conscious beings. It's an artifact. Also the biggest clue your Universe is simulation, and you are engineered." said Jasher.
"I called it the Rise/Rejoin Routine or Three R's." Jasher looked at the studio audience as they sat there in silence, many with their mouths hanging open. He suddenly felt awkward. "It's um, I mean it has to be there before you die so it has to be built into your hardware."
"Wow, I'm a buzzkill. Let me explain why. That's at least interesting."
Jasher got up and started pacing as he was talking. More for him than them, but it got their eyes moving, and that would wake their brains up.
"We discovered pretty quickly that folks could develop weird phobias about the process because your last memory being you just shut off abruptly started getting people talking about how it felt like dying. So, I wrote a little routine that kicks your perception up multiple orders of magnitude, so time is used more efficiently, and you can put a few hours there in a millisecond, complete with the light and the tunnel ride. And yanno, that's a lot better than just being shut off abruptly and feeling like you died when you are suddenly turned back on. When you walk out the tunnel, it's merged seamlessly with your new body and consciousness start. But even if there's a little lag, the tunnel ride is definitely the way to go. It's neat that weird aspects of things all advanced being eventually experience stay the same. That's one of a few things that remain constant in any Universe with any race of beings that digitize themselves. That tunnel ride routine being written by someone very shortly after they start destroying and recreating themselves for whatever reason."
