I believe it is possible that two independent, yet seemingly related incidents can coincide without being directly related. I feel as though this happens quite often. It is human nature to connect things and to look for patterns, however we don't always get this connections right. I really don't see this as a theory, it's more just a fact of reality.
Ye, I do believe that two similar incidents can be totally different occurrences. Coincidences happen every day, they do not have to be related just because they are alike. In reality, a many things that happen,such have a child on the same day and at the same hour is very similar, but one has nothing to do with the other.
There is no such thing as merely coincidence. We are saying with this that 2 separate incidents coincide. Just because they do or do not seem related to us does not mean there isn't a reason for them happening the way they did. The universe is a mysterious place that even our advanced brains can not fully understand.
It is possible but it might just be a coincidence. Seriously, it is possible that two independent yet seemingly related incidents are just coincidence as Carl Jung's theory suggests. It is impossible, many times, to tell whether something is really related or just a coincidence. Coincidences happen all the time.
No, it is not possible that two independent yet seemingly related incidents are merely coincidence as described in Carl Jung's theory of synchronicity, because it is Jung's theory that the events have to be more than casually related. The theory of synchronicity is that the events are related, even if it does not seem like they are.
