How do you tell, &quot;your brain didn&#x27;t produce it&quot;?<p>I don&#x27;t really understand by what your voices are different from what I simply call my thoughts. I mean I also hear random thoughts. Just the same kind of thoughts that you wrote down. Often it&#x27;s a dialog or chatter from multiple different voices. They are different in what they say. 
Isn&#x27;t that normal? Do other people have a mute inner voice?<p>How are your voices different from your thoughts?
