Synchronicity is the experience of two or more events that are causally unrelated occurring together in a meaningful manner. To count as synchronicity, the events should be unlikely to occur together by chance.

The idea of synchronicity is that the conceptual relationship of minds, defined as the relationship between ideas, is intricately structured in its own logical way and gives rise to relationships that are not causal in nature. These relationships can manifest themselves as simultaneous occurrences that are meaningfully related.
