Someone who hears voices, next time you hear voices see if you can re create the voice to say what you want by focusing in on the sound waves of the voice and let your mind go blank and say try saying what you want. I've noticed it can be done and communicated between parties. I'm not sure but am pondering the notion that all schizophrenia is is a connection between peoples vestibular's in close range to each other where mentally ill keep it going and one who hears voices constantly can deafen them in whoever is creating them in a surrounding area by immitating them and telling that person they aren't funny or to be quiet. It can also be humorous to immitate a voice like saying on the highway "Wally's talking signs".
