Really fascinating thread and experiences! I live in Japan, where there are many places deep in mountains called "power spots". People go there and are often fully, or at least, temporarily healed physically (or is it mental healing which has a physical affect?) There are magnetic rocks that have therapeutic effects on the different ailments that especially the elderly have in their later years.
I hear the Japanese talk about these places all the time with wonder and reverence. If that many people swear by their good experiences there, then perhaps there is something to the power and healing effects of these places. I am, admittedly skeptical, though.
