For a long time, many of us realized there were largely two types of people in the world.
The first of these are the NPC sheep caste - niggercattle for lack of a better word. These people have no ambition. They might make a lot of money, even have a couple small hobbies on the side, but they don't really care much about the world. They just exist in it, and the money they earn is so often frittered away on frivolous crap like sneakers or streaming services, yet they then bitch about billionaires. They have little to no compassion for their fellow man, and will easily commit heinous acts if they feel them to be beneficial on their part. They don't care about the evil committed in the world and will often endorse it if you try to force their hand on the issue - "a troon kid never hurt me!" and so on. 99.9% of niggers and sandniggers are in this category.
The second of these are the wolf caste - the "player" characters. We work tirelessly in our day to day lives, saving every penny we can while giving out every so often to the people we truly care about, not to some NGO laundering money for sandniglets. We know the world is fucked and we try to do something about it. We oppose all that is morally disgusting in the world, from eating insects to trooning out children. In past centuries and Millennia, people like us would have been kings and leaders.
And the idea of the world being heavily populated by "NPCs" made the pseudointellectuals cry a LOT. First they came up with that stupid XKCD comic (the mecca of many shitlib opinions about the world) before years of ceaseless gaslighting came, especially in regards to Mandela Effects for instance "hurrrr you remembered it wrong, it was always X".
Then eventually, we discover the inner monologue. Something that was always thought to be in the majority of the population. Nope. Turns out most people can't even picture a red, realistically-textured apple in the heads and rotate it.
They tried to rationalize it at first, believing the idea was just poorly-worded and they somehow confused it for physically seeing an image on their eyelids.
Then, when that turned out not to be the case, they coped. Hard. Because it dawned on them we were right from the beginning; the world is filled with useless eater NPCs and niggercattle, and they're part of it. Rid the world of niggercattle, and our problems come to an end.
I can't really visualize colors well... it's better when it's dark, but I can visualize the wire-frame of a city, a building or any other object. I can visualize flying through a city at high speed. Sometimes I have dreams of places, which however do have color, sound and atmospheres. And I can literally think/imagine to a degree where I ignore what I see.
I am not sure about the inner monologue, because it's common when writing and reading, and when it comes to complex things I often write down my thoughts, even discuss with myself. I also refer to myself as "us" like a schizo, it's like a discussion between 2-3 personalities. Sometimes I also say words audibly when thinking, as that can be helpful... but only in private of course. I know that that part is ehm... "super-normal", but I can't imagine having NO inner voice at all. However not every thought can be reduced to language... and some things are better thought about in a non-linguistic way, whereas the challenge is to bring it into language in the first place.
