Yet I believe this article. Because even I had a spiritual experience too real for me to discredit or brush aside, and I meant it not just mentally but physically too. It didn't completely change my views about religions, but it did soften my stance regarding beliefs since I realized how much it can help someone to believe in something. Even if in the end, it actually isn't real or has any deeper meaning, all that matters is the believer receives some solace. And that is enough good reason for it to exist.
The article mentioned that none of these dreams involved religious figures like Jesus but overwhelmingly had family members and people with close ties. Perhaps that says something about the "real" spiritual world that each of us instinctively understand. Or maybe it is nothing. I don't know.
