…unless there’s reliable, verifiable, objective data
Sometimes I dream weird, surreal, even alarming stuff. When I wake up, I wonder how in the world my brain mixed/garbled so many different elements from my memories. I have to be fully awake before I realize I’m back in reality. My bedtime routine always includes a glass of wine, so maybe that provides some of the fuel! My brain had been busy for the hours I was asleep. But what it if wasn’t just my brain? Is it possible that I was getting input from the spiritual realm? Belief in an afterlife probably arose because people saw deceased friends and relatives in their dreams—so, wow, they weren’t dead after all.
There have been a lot of foolish, even dangerous ideas passed along by people who claim to have heard from the spiritual realm, via dreams, visions, hallucinations. These are the currencies of religions. Commonly, a religious seer just has to describe his vision to an audience of his/her choosing, and voilĂ , people follow in awe of this “person of god.” Christians claim that a third of their god is indeed a holy spirit. (Holy ghost has gone out of fashion!) They insist that their spirit is the truly holy one, and that it is at the top of the hierarchy.
