I have a mixture of both, I have heard commands outside my head that tell me to do terrible things, until I was put on medication I was doing some of the things they would tell me to do so they would stop harassing me. Then I have the ones inside my head, they are two people who talk back and forth to each other about me. At first I thought I had multiple personality disorder and that when I was psychotic one of them "Came out" to the surface. A homicidal mainaic, unsympathetic, mean and angry etc.... I use to just refer to him as Satan, I am still trying to figure out though how they ever came to be? Did I create them? Do I create all of them? This has been happening since as long as I can remember, I am 31 now. I am medication dependent at this point in my life. They seem to come and go.
