These subtle realm interactions may seem like a simple dream relatively considered on the surface. The different implications and activities of Rishi’s all along are extremely advanced. It is not so much about the history of the dream but the details of the psychic mechanisms involved.

Namely, there is a folding of reality within reality, and there could be a realization of that in quantum physics ***. For example:

"I sat down as Tobe, Oliver and the tailor spoke about Oliver as an employee. I figured that I should record and publish this astral episode. My astral body became reclined on an ancient couch. I transported in another parallel astral body to my physical body and jampacked this story into the memory of it."

This is an instance where Rishi evidently “daydreamed” for a split moment*, into a parallel dimension where there exists a super short time concept, even more, condensed than our time effect when compared to the typical parallel subtle realm where events unfold in a few minutes of a dream phase. That doesn’t necessarily mean a shorter time, since the time concept of a given dimension should be considered within its own paradigm and not compared to ours in absolute terms.

In the last sentence of that paragraph, we can note the same entity witnessing his life in co-existing realities, and able to correlate them in one event, and that IMO is remarkable. Indeed, being able to relate to other dimensions even from this real and during ordinary activities are advanced psychic behaviors of Rishi.

Just because it is taking place in a different dimension doesn't alter the intrinsic nature of the ability.

Also, all along he is telepathically relaying information. So it may appear ordinary but to answer the question, this dream is certainly is no ordinary dimensional hop.

Excerpt from the original post:

"Oliver telepathically informed me that he wanted an artist job and that he should already be well known, a famous big shot in that world. I allowed Tobe to be in on this information without letting Oliver know that I told Tobe. Oliver had this idea that it was back in the 1200s in Europe and he would be known in every village as the artist of the royal families. Tobe telepathically informed me that he would have none of it because he had some other employment which would suit Oliver just fine."

In addition, there is awareness of generational relational registry, as to what the relationships were in previous lifetimes, unbeknown to others.

Ultimately, not so much the history of one's whereabouts and relational illustrations, but one's painstakingly developed abilities as the experiences enfold.

Excerpt:

Werner Heisenberg, among others, interpreted the mathematics to mean that reality doesn’t exist until observed. “The idea of an objective real world whose smallest parts exist objectively in the same sense as stones or trees exist, independently of whether or not we observe them ... is impossible,” he wrote. John Wheeler, too, used a variant of the double-slit experiment to argue that “no elementary quantum phenomenon is a phenomenon until it is a registered (‘observed,’ ‘indelibly recorded’) phenomenon.”
