Let's not forget that if one can say that “belief is in the mind” that a good argument can be made for feelings and everything else to also be in our mind. In fact, unless one is dualist, all that we are is in our brain/body, including spirituality. I know of someone back in the 70's in New York who believed she could fly out of a 3-story window while under the influence of LSD. That was not a universal experience linked to LSD. But, the “G” spot appears to be universal even if we can't yet determine all that it does and what purpose it serves other than cause or channel those feelings that we associate with “otherness” and a sense of awe at the grandness of the universe. On a more personal level, one of my JW room mates ended up committing two suicide attempts because he was seeing monsters and hearing voices. Aside from his mind being compromised, I know the JW really screw up his head to the point that he could no longer stand the guilt and tried to off himself. It's that very pathology of the brain that has led to discoveries like the so-called “G” Spot and how alternate pathways in the brain can be created to replace lost functions.
The helmet I referred to in my previous post has been used to duplicate the same or similar sensations in many an individual. Really, it's a poor man's version of what has been done in the lab many times with more sophisticated equipment. So, I believe we all have the same thing in common to one degree or another. Personally, I don't wonder if there are invisible beings. That definition, by its very nature makes it impossible for one to know if the proof is a sighting. But for me, the existence of receptors and generators in the brain like the “G” spot explain why some people insist that there are aliens out there experimenting on cattle and taking people to their ships in order to create some sort of hybrid babies. That also explains out-of-body experiences, etc, etc. This suggests to me that not only there may be a specific “seat” for “spirituality” in the brain but also for the source of mysticism and a general tendency to want to explain the unexplainable in terms of something extraterrestrial or even heavenly. I'm basing my comments on the work of Vilayanur S. Ramachandran, a behavioral neurologist that made several important discoveries while at U.C. San Diego.
