Thanks for the article and describing how you experience “voices” in the head. I don’t agree with everything written, but I find it always interesting to read how different people experience these, I call them “phenomena”. I think there is a difference between possible “negative-self talk” and possible deceptive external voices talking to oneself. I also don’t believe in Darwins’ evolution theory nor that the pre-frontal cortex is necessarily the source of the voices and that it is therefore a parasite, if I understood you correctly. Not saying that this is what is happening to you, but then there also exists technology to put voices into ones head via “voice-to-skull” technology and other ways.
