IMO, most of the time, you're just generating your own synchronicities. As a matter of fact, I'm getting rather good at this. See my dragon-related synchronicities here
These aren't signs from some higher power. These are just blips in the universe caused by your thoughts via LOA.
If I start thinking "Rockchick, rockchick, rockchick" a couple of times per day, within the next week, lots of rockchick-related synchronicity will occur in my life. I may come across stone statues of chickens; or meet a real live female rock musician; or see poultry perched on big rocks, something like that .....
