I've been listening to a book: Opening Heaven's Door.

The authors sister was dying of cancer. One morning her sister said she had a strange dream about her father. They later realized that their father had unexpectedly died around the time of the dream. Her sister then went on to have some interesting experiences around her own death from cancer.

The author began talking to people, as part of her grieving, and realized many families have experiences like this, but nobody talks about it.

Eventually she realized why few talk about it:

She was at a social gathering of some kind and was talking about her recent enthusiasm for this sort of spiritual near-death stuff, and she shared her experience with a man, who she mentioned was a tech worker (judge for yourself whether that deserves special mention). The tech worker listened to her experience and then felt it was his place to tell the author that it was all coincidence or hallucinations created by a dying brain. She then points out that the guy had no special training that makes his opinion any more respectable than hers. The tech guy knew how to use computers, he wasn't a neuroscientists or a doctor or a psychologist, he just felt he knew, probably because he picked up some ideas from Reddit comments or something, and he had to share his opinion.

Anyway, I hold out some hope that there might still be some mysteries in this world.

A lot of people, especially the tech crowd, have been taught in undergrad the importance of critical thinking and evidence supported conclusions. Also, I think the science/mathematical mind is drawn to this line of thinking as well, which is understandable. I know extremely well how they feel, as I've always operated the same way.

That is why faith in some kind of God or afterlife goes against everything we in the tech crowd are trained to do. The hardest thing about being a Christian or believing in an afterlife IMO is the faith aspect itself.

The guy was obviously non-empathic and impolite, and probably clueless that he was causing distress. The only thing in his favor is that he was correct.
