Me, too. I couldn't watch Stargate for years because the deep, modulated Goauld voice reminded me so much of the voice I heard, which was always a man's voice. I always knew that it wasn't real and struggled to make it go away. Eventually, I told the voice that it was my friend and couldn't scare me, and it finally went away. I had terrible hallucinations, too, mostly when I was feverish but occasionally at school (though those ones I had to figure out in retrospect, because they seemed real at the time!)

When I was a teenager I finally told my dad, and he told me that I may have staved off schizophrenia.
