*TW Questions about voices

So, firstly, I don't have any mental health myself, I'm just interested in it as a whole. And secondly, sorry if some of my questions sound naive - I don't mean to offend!

If I could just reel off some questions then maybe some of you would be kind enough to answer! (I appreciate everyone will have different answers and experiences)

Are there particular subjects that the voices will talk about?
Do you get to know and recognise the voices or are they completely random?
Say for instance you were blind folded and unknowingly a stranger came in the room and spoke, could you distinguish between an unfamiliar internal voice (alter?) and a real voice? Does a certain psychical feeling come when you hear the voices too?
Will they ever talk about things that you never knew about?
Do you think of the voices as people/friends?
If/when you talk back to them are you talking out loud or in your head?
Do they have personalities?
If so, do they resemble friends/acquaintances personalities?
If you hear voices talking amongst themselves do they refer to you? And if so, by what?
Do you have an image of what the voices would look like? Do they have a form at all?
And just a little overview of your experience of auditory hallucinations. Thanks!
