So I've noticed when sitting in the silence listening for a ringing in my ear, that I can cause changes in the ringing by moving my eyes around. Could the whistling heard in the ear by many sometimes after you wake up just be Rapid Eye Movement causing this type of whistling? I hear that it occurs in deep sleep and while dreaming, this might explain why when I heard the whistling after waking up I was especially groggy. What I'm really interested in is has anybody ever looked for patterns in REM that might suggest dream symbology or telepathy? From what I read no one has.
