My experience with the phenomena has led me to much different current assumptions.
I have experienced (and documented) synchronicity experiences where the significance is easily identifiable to 3rd parties as long as they are reasonably intelligent and have a general sense of history. In many cases, these 3rd parties did not have to have any personal connection to seeing the "a-ha" about it. It was simply obvious that it was an "a-ha" due to the factors involved and the timing of the arising of the factors.
For example (and which ties directly into the very story I alluded to in my recent return which played a big role in my exit from all forums) was an experiment with the synchronicity phenomena at the heart of it and the Kennedy assassination as the "tie in" or nexus point of all the surrounding synchronicities. My goal in the experiment was to see what would be the conclusions of the individual who participated where I would then reveal to him my conclusions which I had already arrived at prior to beginning the experiment (and which were held in repository by a 3rd party I believed my participant would believe that indeed I had these conclusions, provided them to this 3rd party in writing in advance of the beginning of the experiment).
My hope was that this participant would state that though the probability of these events were incalculably extraordinary, that these synchronicities occurred does not mean that "something" was trying to tell "me" something as to the truth of the theory I developed over the years which, during that time I actually DID believe it very much could be (in fact HAS to be true)... and so as to your comment, Aragorn about it being "belief" - yes indeed that was definitely there... but also, why was I so keen to believe it? Because I wanted it to be true.
The idea of the experimenter was because I saw the whole story (facts and synchronicities) as quite fantastic where I could imagine the more susceptible human being (vulnerable, gullible, etc.) would absolutely believe it was all true, in fact... it is also my theory that this very dynamic is like sunlight and water being applied to a sprouting religion where the seed may have been a single unusual (perhaps anomalous) experience. But I digress.
And so guess how the whole experiment ended up? The whole thing was destroyed by factors that were. themselves, uncanny "coincidences" whereby the participant had long prior to the experiment's ending made a decision I was some fledgling "next Corey Goode!" How ironic. As if I even had time to be such even if my megalomania, narcissism and savior complex where anywhere great enough to try and pull something like that off. After a year and a half away, I finally am able to laugh at it all. And fortunately by so being able to, the threats made back then no longer have any teeth.
