I think - and I could be mistaken, of course - that the problem is the degree of "knowing" that we need. Some people believe they have enough evidence; they do not call it believing, but knowing. Then there are people who doubt others' experiences and also doubt their own experiences! For example, when I saw people who were no longer on this plane, there was no doubt whatsoever that what I experienced was real. My mind was occupied with other stuff (sorting through some lecture notes - not related to death, the afterlife, and the like) when I saw him. The second time I saw another person who had died several years prior, and it was at the grocery store!! As I said, there was no doubt in my mind; but as the days went by I began to wonder....You're welcome, mac.
Good point about the doctor who had never previously met the patient, raven -- I'd forgotten about that one.
The "little voice" you mention is inside me too, at least sometimes. I occasionally have a sneaking suspicion that when I die I will end up in a loving afterlife where my husband and maybe "god" will jokingly give me a verbal slap upside my head, saying "See? You knew it!". And I'm ok with that, lol.
If you're right that there is something greater, I really don't understand why it should remain a mystery, or at least so much of one. It would make a massive difference to me, to know for sure that an afterlife exists, and I'm sure I'm not the only person who would be affected that way. I can understand that while living our regular human lives we may not be ready or able to know or understand all the details, but just knowing for sure that an afterlife exists, that it's a good place, and that we will be reunited with our loved ones there is really all I would need.
I also think that for some people, no amount of evidence/proof will be enough because the need to make contact with the deceased is enormous. In fact, I'd go as far as to suggest that even if we saw a loved one and interacted with him/her, after the experience the doubt would creep in again, and we might end up dismissing the entire experience. For me, the beginning of my search for answers began when I saw "something" leave the body of a hospitalized 53 year old woman. At that point in my life I was still a staunch atheist, but that was about to change. Perhaps that was the first pop on the head I received from the Universe. (Some people call it God, some may call it The Greater Reality, I choose to call it The Universe!).
I'm inclined to think there is an afterlife. I continue to be particularly interested in veridical perception accounts; still, my search for answers continues
