A "God Helmet"? Thanks for the link - very interesting will have to find out more about this man's work!
After a quick glance it reminds me of a time when we were out in the country near a lake and one night we could literally feel a wall of energy on the balcony of the cottage we were staying in. Apparently this was merely something to do with the magnetic field surrounding the water.
Will look into Persinger's work in more detail. Thanks for letting me know about him.
best wishes
Ingrid
