How can I say yes if I'm still here?
I've read cases of young people dying in their sleep, but they had no connection with astral travel. It's safe to say that no matter what happens to your astral body, it doesn't actually harm you physically.
Why don't you start practicing and see what you can find out?
Now, I don't usually share my experiences anymore, but, since you're asking, I've tried to request my early liberation from the flesh when I was out there a few times, and when I got really loud about it someone came running to stop me, telling me not to do that because I was irritating the invisible powers. So, I got their attention but they would not comply with my demands.
We will all die one day, for sure, so it's best to use our time here for self improvement. Let them decide when that day is.
