The OP is mired in Cartesian duality and ego-identification.

I could barely keep my eyes open.
Look at the assumptions in the premise:
So the deal is, the first thing that happens when you arrive is you get dumped into a yellowish or brownish meat-bag filled with red and white.
"When you arrive?" Who is "you?" Where is "you" arriving from? For that matter, where is "you" arriving
to?
"You" must be separate from the body, because "you" is
dumped into a "meat-bag." Meat-bag is clearly idiomatic Jerkass for the body.
Does "the first thing that happens when you arrive" mean that the sequence of events is
- "You" Arrives From (???) to (???)
- "You" is abruptly dropped or falls into A Body
That would seem to imply that wherever "you" arrive to is above the body you will be dropped or fall into.
I don't really care. You started off with the Cartesian flaw, you can't get anywhere once you allow that. Once you embrace Cartesianism, you're talking about religion. I can consult my own pineal gland, thank you very much.
Though I really enjoy the use of the word dumped. That opening line evokes images of angels swooping down from Heaven and crapping souls into little babies.
