It really helps to picture being stuck upside down in the thing. I thought, “surely you could gradually rotate yourself the right way up” before I saw the photo.
I'd ship myself in a nice big coffin with lots of soft upholstery and leg room to stretch out. That way if the worst happened and I died en route, nobody'd suspect foul play.
When I was a kid we were playing around and I got zipped into a suitcase. I had to really "get small".
I was completely fine for a while, until a little while in it was like a switch was flipped and I was "let me out omg let me out". I freaked out. then I was out and was fine. But I remember that extreme claustrophobia moment.
