I had a dream that explained to me, that retarded people don't realize they're retarded but instead they're using all their unused brain power to imagine living out a life very similar to how someone lives life normally and to them, they're completely unaware of the real world and their actual self is just on auto-pilot forced into a dream-like state because of trauma or whatnot. This could also mean the reality we're experiencing right now is a fake and is all being imagined using up all the thought capabilities of your real self and that's why retarded people seem retarded, they're not connected to the real world.
That's also why retarded people mumble random words or gibberish most of time, that's what their fake self is thinking but little do they realize, they're actually saying it out loud in another reality. Meaning, anything you could be thinking, you could be saying it out loud and you wouldn't know. The dream also explained to me sometimes instances of half and half exist where someone develops separate selves, one dedicated to the real world and one dedicated to the one they're imagining being that they're half-retarded in both. This could also work like 70% and 30% and is not always exactly half and half. It also explained that all humans have the same level of thinking capabilities, but most times we don't reach it due to becoming segmented and fragmented like this and others will be smarter due to being less fragmented.
As for the dream itself, I imagined I was in some sort of compound, not exactly a prison but an elaborate building in some similarities and sorts. In there, I met people who I had seen/met in real life, only in real life those people were retarded, but in the dream they could talk and act normally. There were also people who I met who were normal in real life but retarded in the dream and some who were still normal regardless. And each time I would leave the building, I would suddenly get placed back inside into a random room. All the while, I could experience and feel my other self who had already left the building and in some instances, I went back inside in which entering the building would also place me in another room but without being fragmented. It was like being 2 people at once. Basically imagine leaving a building in a video game only to have another screen appear showing you still inside the building in a random room and you can still control both versions of yourself only it feels reduced.
Despite this, the dream felt like reality, it felt like I had been in that building for a while and I didn't question why I was there or how I got there, but at times I felt like I needed to leave. And I even became confused when some people would tell me that the reality I was experiencing is all fake and that I needed to wake up or else I could have the chance to be stuck. More specifically, they told me I had to exit the dream in the "correct" way and not try to leave the building if I could help it. In hindsight, it seems frightening as fuck, but I didn't think much of it inside the dream itself, it wasn't nightmarish at all.
That's the gist of what I can remember, but if you want I could list specifics how some rooms or things looked. One that really sticks out to me or one that I have the easiest time remembering was a sort of multi-layered grated / chainlink fence room. It was made almost entirely out of metal gratings or mesh and very dimly lit. I think it worked as a sort of hallway between rooms. I remember it being the only room where I couldn't find anyone to talk to and it was also the last room before exiting the building or entrance room if you will. There was some structure to how the building was laid out, it didn't feel completely random, but it always felt like 10% of rooms led to that particular one.
And for reference, I have never done any sort of mind-altering or hallucinogenic drugs in my life. But I have always had bizarre sorts of dreams, some that even continue from where other dreams left off like a sort of show. I can describe some of those to if any are interested.
