@hermes Why do I get the sense there's a reason you are passing on this information onto me in a form I am willing to accept? Yes I realize there is a vast ocean of information we can tap into and that as an Empath, that is what I do. I also have a sense, albeit a vague one, there are networks of interaction in other realms that are analogues of this forum and so forth.
I've experienced what I refer to as other realms and as seems "typical", they were more real than so called real (3D physical reality). I interacted with one being (female). I also interacted with a vast 'thing' like a landscape with green and white regions that were not in perfect geometric shapes. It was neither, by analogy, wholly machine or wholly organic; it had characteristics of both. However, perhaps the most vivid experience was that of being in front of an intricate blue and white geometric pattern whose vibrations I interacted with. The vibrations were of a very fine nature and permeated "me" (or what I perceive as me). I have the feeling the point of these experiences, given my background, was to bring me into full awareness there is more to things.
I think I get the gist of how you're using "dimension". It's clear to me that for whatever reason, one thing I intended on doing here on Earth during this lifetime is to become expert in multiple so-called "disciplines" of science, including what is called physics. I have baggage here and use dimension in the sense in which it's used in physics. I seem to struggle to tune into the sense in which others, like you, employ the term; but I have the sense that it is important for me to do so.
There are not 4 physical dimensions because time is not a dimension. Time is used by analogy with physical distance to refer to states in the physical world that are "apart" due to changes in the nature of the physical world.
The reason I say all this is that words lack the precision needed so it's a matter of trying to get a handle on the meaning via context.
I feel compelled to ask, based on what you say above, whether you think the so-called Mandela effect is people noticing changes actually manifesting in their 'dimensions'. I take it you mean something along the lines of a particular path through (manifested) "3D reality" that may or may not overlap with others' paths? Is this a reasonable take on what you say?

I'm fascinated about the Mandela effect. Having a background in Psychology, it's easy to "dismiss" based on experiments on memory, such as related to Court proceedings. However, Psychologists don't like to talk about Parapsychology which has demonstrated way beyond doubt that various things like ESP and remote viewing are real unless you contend a sizable conspiracy.
