In locus deii - bad Latin for "in the place (person) of God." Sorry. But in the spirit of Rabbelais, "non catchibus, non castigus" -
Old Dood-
I do PLRs as a standard office routine, and there seems to be nothing but a sequential organization of the type in which "A comes before B". It is possible to slide backwards up the time line to return to prior events, or to slide forward to view the future in some form, although there are a great many alternative futures to be viewed. There is also an excellent argument, based on PLR experience, that we do not always live in calendrical order - but occasionally we jump from today to a time in the past, or the future, and occasionally in a limited form, while a more advanced future form remains "on hold". For example, one person reported becoming a rabbit briefly, as an educational experience dealing with a life as a miner in which she had lost a child. Then she went on with another life in the caves and mines.
I've been told that the universe started as a single "event" by one person who went there to look, and whether for good or ill, Los Angeles has been seen to be happy and well in about the year 2200.
My personal suspicion is that we're getting more involved with the "meaning" of time than what it actually is. But maybe that's what time essentially is, a meaning imposed arbitrarily upon suchness.
Anyhow, here's a practical suggestion - if you do a regression, get a recording, preferably video (less boring to review). Between normal memory and the recording you'll retain everything.
