I'm very introverted as well.
Here's what I think of the human mind.
I consider Memories, Ideas, Considerations/Ideas, Objects, and Emotions to be inside one's mind. Each of these categories affect each other.
Memories defines what you remember, heavily laced with imperfections created by Emotion, which is in turn created by Memories.
Considerations and Ideas defines what you think of various things and what your decisions are. These are affected by Objects, and they also play into your Emotions and by proxy your Memories, as you may analyze what others say and do with you altered perspective and what you find to be reasonable. These could also be called reasoning and logic, but I think that that is combined with Objects for practicality and brevity.
Objects defines what you know or think you know on a purely platonic level. These are altered by Emotions to create ideology but pure Object can be defined as something like a math equation. It's something quantifiable and scientific. Ideology is merely your logic and Emotions mixed with your Object. What is morally right to you.
I won't get into more detail about what may be mixed to create different aspects of your mind. And I am not a professional. And I'm learning and growing. This is me putting what I have subconsciously picked up into communications. It is similar to attempting to explain high level computer language with low knowledge of what it actually is. But it is all I have. And it is what I can give. This is very technical by nature; the human mind is a complex working. I hope this provides insight on how my mind works.
