I've found that that any of the main synchronicities I've experienced, the ones that are most meaningful to me on my path that I can almost sense them before and as they happen.
It's more of a feeling like after it happens I think to myself "I knew it was coming" almost to the point I could've wrote it on a page that I'll experience something of significance today.
This leads me to believe that it is both a process of manifesting it on your own alongside the universe giving you a sign you are on the right path.
