We can find the info on the Dome of Naguals in The Second Ring of Power:
"In that particular vision, I had found myself looking at an outlandish world. There was an enormous rock right in front of my eyes, a rock which had been split in two. Through a wide gap in it I could see a boundless phosphorescent plain, a valley of some sort, which was bathed in a greenish-yellow light. On one side of the valley, to the right, and partially covered from my view by the enormous rock, there was an unbelievable domelike structure. It was dark, almost a charcoal gray. If my size was what it is in the world of everyday life, the dome must have been fifty thousand feet high and miles and miles across. Such an enormity dazzled me. I had a sensation of vertigo and plummeted into a state of disintegration.
Once more I rebounded from it and found myself on a very uneven and yet flat surface. It was a shiny, interminable surface just like the plain I had seen before. It went as far as I could see. I soon realized that I could turn my head in any direction I wanted on a horizontal plane, but I could not look at myself. I was able, however, to examine the surroundings by rotating my head from left to right and vice versa. Nevertheless, when I wanted to turn around to look behind me, I could not move my bulk.
The plain extended itself monotonously, equally to my left and to my right. There was nothing else in sight but an endless, whitish glare. I wanted to look at the ground underneath my feet but my eyes could not move down. I lifted my head up to look at the sky; all I saw was another limitless, whitish surface that seemed to be connected to the one I was standing on. I then had a moment of apprehension and felt that something was just about to be revealed to me. But the sudden and devastating jolt of disintegration stopped my revelation. Some force pulled me downward. It was as if the whitish surface had swallowed me.
Nestor said that my vision of a dome was of tremendous importance because that particular shape had been isolated by the Nagual and Genaro as the vision of the place where all of us were supposed to meet them someday.
Benigno spoke to me at that point and said that he had heard Eligio being instructed to find that particular dome. He said that the Nagual and Genaro insisted that Eligio understand their point correctly. They always had believed Eligio to be the best; therefore, they directed him to find that dome and to enter its whitish vaults over and over again.
Pablito said that all three of them were instructed to find that dome if they could, but that none of them had. I said then, in a complaining tone, that neither don Juan nor don Genaro had ever mentioned anything like that to me. I had had no instruction of any sort regarding a dome.
Benigno, who was sitting across the table from me, suddenly stood up and came to my side. He sat to my left and whispered very softly in my ear that perhaps the two old men had instructed me but I did not remember, or that they had not said anything about it so I would not fix my attention on it once I had found it.
„Why was the dome so important?” I asked Nestor.
„Because that’s where the Nagual and Genaro are now,” he replied.
„And where’s that dome?” I asked.
„Somewhere on this earth,” he said.
I had to explain to them at great length that it was impossible that a structure of that magnitude could exist on our planet. I said that my vision was more like a dream and domes of that height could exist only in fantasies. They laughed and patted me gently as if they were humoring a child.
„You want to know where Eligio is,” Nestor said all of a sudden. „Well, he is in the white vaults of that dome with the Nagual and Genaro.”
„But that dome was a vision,” I protested.
„Then Eligio is in a vision,” Nestor said.
„Remember what Benigno just said to you. The Nagual and Genaro didn’t tell you to find that dome and go back to it over and over. If they had, you wouldn’t be here. You’d be like Eligio, in the dome of that vision. So you see, Eligio did not die like a man in the street dies. He simply did not return from his jump.”
-- Carlos Castaneda: The Second Ring of Power
I have always had the highest regard for the writing genius that Carlos Castaneda actually was. His literary devices were superb. For example, he knew that he was introducing fresh and new information into the existing framework of anthropology and shamanism back in the 60s. Hence the invented character (himself) in all of his books was slow, generally emotionally unstable, and overly rational academic (in our real world, in his seminars he was a completely different person, I hear).
In his true state, he must have known perfectly well that the Dome mentioned above really existed, not on this Earth but in the specific position of the assemblage point.
The Dome is real, and anyone with enough energy and awareness can indeed visit that place in dreaming.
Not only do Naguals frequent that realm; I have seen there many other dreamers of whom surely not everyone was naguals. In dreaming, I have met Taisha Abelar there and conversed with some other members of Don Juan's party as well.
Perfectly serene and devoid of any dark inorganic energy, the Dome is there for all dreamers to visit and learn the inner secrets of the art of dreaming and stalking.
At the very least, I see it as a meeting place for dreamers who are intending their freedom.

In our Maya Lineage, there is a complete world, the realm of Mayan Naguals, the Jade realm, where all Maya dreamers (and other permanent dwellers) congregate in their Light (nagual) bodies and further their skills towards complete freedom.
