Fully empathize your puzzlement about synchronicity)
Want to share my story with you.

Once, I was leaving a bar and stopped near the entrance for hugs and good buys, when friends asked me, if it's convenient for me to share a taxi on the way home - and at this moment (time went as it felt a little slower) I thought “no, I need to go alone by metro and more over I need to wait a little now before going” I continued a chat till the taxi came and went alone to the metro. This very station has 2 escalators which you need to change on the way down (or up) and some space between - for 10 steps I suppose. So when you go down and somebody goes up - you have about 4 seconds to meet. When I entered, I felt that I need to go down the escalator (instead of standing till it moves) and when I'll be in this space I'll meet a concrete person. So I did it. And met this person. It was very strange)

And another story.
Once, I was recommended to friends of friends to make some photographs at the anniversary of their 3-years old daughter. When I came on the scheduled day I was explained, that I need to get through the market on the corner of the house to get at the back yard where entrances are situated. Here my battery went out. It was a multistage building with 2 wings forming a right angle. When I crossed the market from the corner point, I didn't know where to go - left or right, and I chose to go right - counted entrances 1...2....3 - looked at the tablet with apartment numbers, found the one I needed and entered. In the elevator I met an aged lady, she pressed 10th floor - me 11th. She started a chat on ecology, world issues, greenhouse gas etc. We discussed a little, she left at 10th floor, me at 11th, where I found an apartment, but it was empty - nobody opened the door. So I decided to check the left wing and got outside counted entrances again 1...2...3.. tablet also had the apartment I needed. I entered and in the elevator I MET AGAIN AN AGED LADY (another) she pressed 10th floor (!!!) I pressed 11th. I stood quiet, hoping not to hear of ecology or gases)) The lady was quiet. But it was also veery veery puzzling)
