The oldest city lost in the void of confined reality

Leaving the body behind I went with a guide to see something I believe to be very old, he the strong silent type stoically guiding me through something that makes another kind of sense than supposedly logical reality...
Through veils of darkness and deeper metaphor (such as a swimming pool with a blurry grey light through which could be sensed abandoned high-rise constructions with a mountain background) we eventually were overlooking some sort of place... a city.

It felt alive. The city itself, like it was organic, a living beast lying there with inhabitants within... There was nothing but the city to be seen, as if it was all that existed in this dimension. It was large, I was seeing it from above seeing details and larger structures almost all some sort of sand stone... the hues were soft pink, red pastel, with darker shades and sometimes green, I felt was the colors of the innards of a beast. There was a population in these narrow streets going on and about in some strange madness. I felt it was an old disease, they were doing their own time most just walking, some selling and haggling, some on street corners screaming... some whoring... killing, feeding, bleeding, sweltering underneath the heat of old crazy... among the stones, some rubble, fights and accusations, in a general cadence of antagonism. Everyone was on their own. They were all staring at each other, or overly conscious they belonged to a group throng knowing how fast it could turn on them if they weren't vicious enough... hard to describe.
It was one of the oldest mentalities I can think of. The kind of city with bearded balding old aggressors half crazy half evil, unconscious in their actions, hurting and sinning without thinking. Stone, sand, clay, dirt. There was no serious technology. I quickly thought of the Babylonians or the ancient hebrews. It was utter, organized chaos... a very high degree of competition... no joy except that to have swindled a fool. Greed. People did not sleep. In the depths of the city more obscure things, primal discomforts, more silent, way less crowded. Almost subaquatic. A very old, very deep bizarre, from a time maybe even since dinosaurs. Perhaps older, I don't know. There was no good virtue in this place.
I was watching such frenzy and understood that every single soul in it was likely to know completely well that it was their trap. That what kept them trapped there was to be found in some aspect of their own selves. In the way they think. The way their logic goes. And some of them were fine with that. Some of them despaired. But most of them, upon somehow entering it, eventually lost themselves in this city, and became like all the others. Even just to survive. And many would eventually never come to leave.
My guide told me that all dark thoughts feed this city. All curses and hatreds and despairs end up in there. These persons were trapped down a hole they threw themselves into and could rely on no other strength than their own to climb out again. The city felt familiar to me.
I came to the conclusion that the only way to escape this deeply cursed place is to be a selfless, genuinely good person... of course these damned would be allergic to that, and if something was to happen inside on such person down there, I'd be tempted to believe every single citizen would turn on that person and become completely hostile... with nothing else could calm them down but the person surrendering their retrieved inner light. There is some sense of deep disruption, and they are causing this to each other, in a way that perpetuates and guarantees nothing but restless misery.

At some point earlier I was being guided by a something that was telling me about how I have multiple facettes of myself that are all akin to version good and bad, and that they are all trying to get somewhere. I almost feel that I am being warned. I was warned back then with dreams about the Communist church realms and the hundred floors Lubianka. I might be exploring lower astral levels.
Good news however, although maybe only for other than me... I think that if the red-dark city is the result of the way thoughts influence reality, in that case negative ones, then personally I conclude that there must also be such a city that is its opposite. A place which shines lighter as it imbues itself with all of the lighter thoughts. What a place that must be. But, maybe I won't ever see it. Since, if my guide is showing me the dark version, it is either easier for me to understand the underlying concept that way, or I am at risk of ending up in there.
This is the kind of place where there is no way to escape from it but to be made anew. And to forget everything.
Well, play Agony.
