Fear of hell, advice please

[GrandizerII]

If random youtube videos reinforce your belief in Christianity then that's a very low bar you've set for yourself. Do you believe a cat can play the piano?

But the thing is this guy is so genuine, he is crying, he really believes he met Jesus. I just cannot find that with other faiths.

Here is one consistency your are missing. They are all personal opinions from delusional people in a delusional state of mind. There will always be some consistencies when common religious beliefs fire their delusion.

but why do Christians have such vivid and detailed delusions while others don't? Shouldn't Muslims, Hindus, Buddhists all have NDEs with lengthy and lucid discussions with their deities?

Sincerity doesn't automatically mean truth.

And, again, Christians may have more vivid and detailed delusions partly because a whole lot of them are situated in first-world countries and/or hail from cultures that promote individualism (as opposed to collectivism).

It also seems like Muslims have to stay quiet about whatever visions about Muhammad they may see, lest they be punished/ostracized or something.

So many ways to explain the phenomena you see without ever having to appeal to the supernatural. We're a very interesting bunch of animals, with lots of biases and distorted thinking, and a study in psychology would help to clarify that even more.

Also, do read up on "confirmation bias" and make sure you're not falling victim to that.
