This is an interesting article on a potentially interesting (but paywalled (anyone have a link?) study.<p>> 20 patients with schizophrenia in San Mateo, California,<p>One of the criteria for treatment (at least in the UK) would be "Does this interfere with your day to day life?" Friendly voices would tend to not meet that criteria. Modern treatment should include developing ways to live with the voices, rather than just medicating them out.<p>I'd be interested to see what happens if you include people who hear voices but who are not patients. I know a few people who hear voices, but who describe them as usually okay and only occasionally distressing. They describe similar "providing useful advice" experiences.<p>Here's someone who describes what hearing voices is like (he hears mostly external voices - a voice which sounds exactly like someone is standing behind you, talking to you, except there isn't anyone there) and an internal voice. He describes some of these as distressing and frustrating, but he talks about the first experiences as being friendly. And that, from the little bit I've heard, is a reasonably common experience even in the west.<p>(He talks about some distressing events from his childhood, so go careful)<p><a href="https://youtu.be/LNAuckNrC34?t=15m20s" rel="nofollow">https://youtu.be/LNAuckNrC34?t=15m20s</a>
