Coincidences happen, yes? “Do they have meaning?” is a more difficult question. Synchronicity, and by association the fractal nature of reality that is such a common vision for psychonauts, and is such a recurring motif for New Agers, intuitively holds the key. For this post, the question will be reworded as Is reality fractal? with the collarary being “Are coincidences meaningful in that they refer to a higher system of meaning?”
A constituent element of a fractal is the ability for the part to mimic or represent the whole. Any arm in a spiral fractal can be found to contain spiral arms of itself which in turn contain their own identical spiral arms, and so on.
Is reality much the same?
For example: I see the like/dislike spectrum of human experience to be very associated with negative and positive charges inherent in atoms themselves. Even on the smallest level, matter divides itself into “attract/repel”, two opposites with no consciousness of their own, but which perceive, and act on perception.
Also, I sensed it while tripping. So did Jeff.
Similarly, you see this in studies by which humans instantaneously are attracted to or repelled by an object or concept, only after which are they able to find reasons for the attraction of repellence - a type of reverse causality in consciousness. Perception is the true king, with rational thought following nude and silly as the Emperor.
Matter knows matter. On what level? According to astronomy, gravity entails every particle affecting every other as space-time bends. According to quantum mechanics, particles become entangled and never part perception, despite distance or time - it is possible that the entire universe is one entangled mess on the sub-sub-sub-atomic level. We’re all connected by the forces that govern the universe. What forces and laws do we not yet know? And what implications may they have?
This, incidentally, makes prophecy theoretically possible, if you accept that reality is fractal, and that the fractals can be perceived (usually in altered states of consciousness). By being able to sense the greater pattern’s rhythm and form (which has to be done on an intuitive level, considering the greatness and complexity of existence on our one planet, much less the universe), it may be possible to see how the lowliest and most mundane phenomena can be related to the future and past events on a grander scale. Reading such signs... is most likely impossibly difficult without using a different form of consciousness. Dreams? That's where a lot seem to come from, and it's where all my deja vu has its genesis.
Other people’s beliefs in these phenomenon give me hope. I‘d rather not divide the world into “rationals” and “others”, considering how the definition of rational has changed throughout history. It is a short-sighted person indeed who believes that not only can all be known, but that reality can be extrapolated by the things we’ve figured out in the last couple hundred years.
I think I’ll put my faith in what has been figured out in the last couple thousands of years.
And finally, do coincidences have meaning? THE ANSWER!!!!: maybe.
