I'm a guy who started hearing voices after a mental episode. Schizophrenia is in the family but difference is that I only hear voices on important moments.

One month I started getting interested in using some found abilities of my voices on books, (you can find them on my previous post) where my lack of time to start getting deep into a book, allowed them to start using different speaking styles. My point is that the voices re-enact what you mind absorbed and/or craves for. I concluded that those with the illness have still not found patterns of mentalities that triggers their respective illusions and normal people live the unexplored easy patterns with no consequence. That's why I decided to poke them since it's not as bad as the main ones with the unfortunate complications. Somewhere in between I think I can find what they are.

In many conversations with them, I started putting away possibilities and my conclusion was that the voices belonged(and/or still belong) to a sort of mental parasite that exists inside triggered brain games and today became an entity that rests in some resulting untouched curiosity of the first games thanks to the respect people have to sensitive situations in the Bible, where some took a bullet for us, inside what we don't really understand yet (for example).

In case it's all a big misunderstanding, the voices, affecting normal people, have a lot of: 

1-Gaps in their way of minding/speaking- When the voices go silent they can't be mentally reached at that moment, but those who heard it previously have believed it was a moment where it's either too rude to answer or too pleasant for a reply 

2-Impossibility to truly find them today- It takes mastering knowing the effects of some states of mind to find what they are. Thinking about thinking something. While my questions about them are sometimes challenging the right place of my mind (like thinking about something else, in this case, a felling that you have said something disrespectful)) the entity takes an unknown effort to prepare to do/say something suiting that change. If successfully managed the voices are probably a mirror towards you own mind, since they adapt to what you are gaining or lacking (still considering the book point). But today it's still a long road to walk, if possible.

3-Hunger for either oxytocin, dopamine, or serotonin-These are our "happy hormones".They cause you to feel a surge of positive emotions. The voices don't answer whenever I have a new idea (I think that's dopamine). I'm trying to find a connection between presumed Higher entities and these 3 chemicals. So far I found only Enki the God of creation, intelligence, crafts, water, seawater, lakewater, fertility, semen (oxytocin), magic, mischief in sumerian mythology.
