Inner Monologue

Inner Monologue is an amazing experience where normal human beings can discuss or describe things to themselves. These "discussions" can be as simple as a monotone voice but can also be as intricate as vast adventures within a three dimensional world that the human creates with just the power of their own mind.

People who do not have an inner monologue are in a sort of poverty where they lack even the concept of what an inner monologue is. Much like a deaf man trying to imagine what a symphony sounds like.

Silencing

Going to the next level, humans who can silence their inner monologue at will are just that much more special. Whether they use prayer, breathing exercises, or can do it on their own with just the power of their mind, finding that "quiet place" allows these people to be able to experience the calm world of an NPC while also enjoying the power of the inner monologue.

NPCs

There is no such thing as a medication or medical technique to give a soul to a soulless being. You are an NPC; a side-character. A form of biological AI.

Aphantasia

I have aphantasia. I don't care. I didn't even know I had this "condition" until I saw this meme on the internet last year. Not everyone's brain works the same way. I have a STEM PhD so it's not like I'm retarded. - AI based text response
