there are stories of people hearing radio broadcasts "in

I can confirm that effect ! I have a porcelain/stainless steel gum
implanted prosthetic tooth. I can occasionally hear radio broadcasts
in my head. Most often when I am in bed at night when its quiet. I
found that clenching my jaw will instantly stop the effect, but I
haven't discovered how to make it happen on demand.
