I really want to have a near-death experience.
Why would you wish to have a near-death experience?
I've always thought it would be enlightening.
Although your reasons of wanting to feel enlightened are a noble reason to want to have a near-death experience, it's not worth the risk and danger. You will very likely actually die if you seek out a near-death experience. You should consider mental health treatment if you are thinking about death on a regular basis.
It's a pity to think about death because you won't be buried when you die.
I really think what you are purposing here is dangerous, and I hope you're listening to me when I say you should seek out some mental health treatment.
