Vernon Lenk Posted 7 months ago do you hear voices? This was 30 years ago. I remember reading a book titled "The origin of consciousness of the bicamerical mind.. Something to do with consciousness evolving from words. It claimed that 3% of the population can with sufficient stress hear voices in there head. The formation of words crated thoughts and ideas that for many (Greeks, 2000 years ago), were as if from the gods. I thought at the time it laughable. I tried to simulate the conditions, in my apartment at night, alone, totally quiet. I really fhought this was silly. Nonetheless, I did hear a voice, so freightening. I can't remember what, yet I believe I would do anything the voice asked. I have never tried to frighten my self like that since.
