Quick question - do the voices sound like anyone you know or have known, or even possibly like your rapist? Or are they unique and set apart from anyone else?

I have dealt both with auditory hallucinations and PTSD in my life. I do not have schizophrenia, but I used to determine some parts of my PTSD were PTSD or auditory hallucinations by determining what type of voices I was hearing. Perhaps that can help you.
