Synchronicity is cool.
Synchronicity, or finding meaning in otherwise unrelated events, is a symptom of delusional psychosis.
According to research, every new thought, every new bit of information, is initially accepted prior to evaluation by way of refuting the data in order to filter it out, discard it, or dismiss it. Psychological/Neurological dysfunction may be affected by a failure or bypassing of the refutation process.
So the initial stage of processing accepts all information as equally valid with the next stage being the part that filters out the erroneous. When the refutation stage does not work properly, synchronicity is the result, in that you connect events together as having some kind of association when they actually do not.
Example: You glance at a clock and it's 11:11, the next day a clock/watch that is also showing the time to be 11:11 catches your attention. This seems to happen quite frequently so you start to believe it is some sort of sign and then you begin a process of trying to figure out what that sign might be, with the internet frequently playing it's part in the collective insanity by way of groups of equally unstable individuals gathering to share their 'real' delusions.
Explanation: You subconsciously take in the surrounding data of your environment simply by going about your usual activities. This includes the frequent information sources regarding the time, clocks, watches, computers, smartphones etc. You don't retain the memories of all the times during the day your eyes scanned across an area that included something showing the time, but it is when the time actually is 11:11 that the casual scan suddenly causes an emotional response of shock or surprise because the previously unimportant visual data where the time was not 11:11, now contains visual data where it is 11:11, thereby making you feel that you are only looking at the time when it is 11:11, which must, therefore, have some sort of meaning. It does, the one I just explained. It doesn't 'mean' anything else.
It is fallacious reasoning that leads you down the rabbit hole of psychosis. You discard all the data that doesn't fit your narrative and focus only on that which does, or at least can be crowbarred in to your ongoing delusional narrative.
