Solid choice lol. He would do the hand gestures and the dances and everything.
I'd rather experience the afterlife for a moment, because then I would know that there is, in fact, an afterlife to experience - that the afterlife is real, which has always been a big concern of mine. I would also have to know for a fact that what I was experiencing was indeed the afterlife, and not some kind of hallucination.
Not that I wouldn't want to encounter a magical being though. That would be hard to pass up.
But it would be so comforting to know the afterlife is real. I wouldn't start being reckless or mean and feeling like nothing mattered because I was guaranteed another life after death - I would still want to live my life out fully. I would just have peace of mind that those I love aren't gone forever, that I will see them all again, and that when this life ends, it isn't just oblivion, it isn't just over and that's it, but instead there's something more to look forward to.
Good, thought-provoking question
In a similar vein -
would you rather know for sure that there were aliens?
Or know for sure that myths and legends on Earth were based on real events - that stuff like wizards and dragons really existed on Earth before the modern age?
