The trip was reliving the person's life from top to bottom, and at various points hearing huge applause or boos or an emotional rection of some kind, and turning round and seeing that they were on the set of "This Was Your Life" with a huge studio audience. The presenter would give a prize, joke or something and ask some questions which led back to reliving their life and soon forget about the "show" until the next time the crowd went wild. It is said it felt like a lifetime, I don't know how long the trip lasted in measured time.
That's nuts. I wonder if that's your subconscious acknowledging the conscious. Or your meat hardware looking inward at the ghost software or something.
