On episode 268 of Howard Hughes’ “The Unexplained he interviewed Dr. Caroline Watt of Edinburgh University. At about minute 13:30 (and again at 24:35) on my itunes version of the show.
she refers briefly to the ganzfeld effect. It seems to have some different wrinkles in her hands. You might care to try to book her?
It isn’t a particular interest of mine, but I mention it in another wild stab at trying to be helpful.
