You're in a rocket on top of thousands of tons of explosives, everything runs automatically, there's terrifying noise all around and you don't control anything.
Blacking out in dissociative euphoria still sounds like a feature, not a bug to me.
I had a similar experience recently. Massive turbulence on a commercial flight low over the continental divide flying into Denver.
I personally witnessed 3 people vomiting, but I was all smiles the whole time. I am in small planes a lot, so kind of enjoy the bumps when it’s someone else’s job to fly now.
I suppose that if we ever develop some sort of hypersleep/suspended animation or whatever we want to call it then being dissociated by a noble gas before the system kicks in might be a good idea.
