Synchronicity or meaningful coincidence is the most conscious aspect of the underlying web of reality that connects everyone and everything.
As humanity's consciousness expands and new paradigms and worldviews are born, synchronicity is more evident in mass events like, 9-11, the shootings at Sandy Hook and Aurora, the explosions at the Boston Marathon, in extreme weather phenomena. It occurs in alien encounters, often is intertwined with paranormal experiences, and may act as an interface between life and death. It happens frequently when our lives are in transition.
Once you're aware that coincidences are meaningful, you're on the synchronicity highway, traveling through a kind of quantum weirdness that features astounding odds, tricksters, messengers from the unknown, the unseen, the seemingly miraculous. When you're on the synchronicity highway, you're exactly where you should be.
