Well I have a couple of examples that look like synchronicity but probably arent and one that is.
25 years ago I used to work in a particular company and there was a guy in my team called Raj.
Some 15 years later, out of the blue and for no reason, I started thinking about him. A few weeks later, I was walking in the neighbourhood of my office one lunch time and I saw him in the street. We said hi, caught up, and he told me he had been working there locally for a few weeks and would be around for another few, and true enough I saw him around most lunchtimes thereafter until he left the area.
Initially, I thought it was 'spooky' how I'd suddenly thought of some guy who hadn't crossed my mind for 15 years and there he was, when I put my logic hat on.
I think the most logical explanation is that I had started seeing him around when he moved to the locality, but not recognized him immediately, my sub-conscious had got to work on it and had finally identified him, and saying 'hello conscious brain, do you remember that guy Raj you used to work with' and so next time I saw him I recognized him.
Now here's another example. A few weeks ago, I learnt the word 'nzil' in arabic which basically means 'get down' (like get down from the bus or whatever) and now virtually every bus I go on, I hear people saying 'nzil' whereas I didn't before. I'm sure the whole of Cairo didn't just suddenly discover that word at the same time but it was there all the time, waiting for me to become aware of it.
Now an example that probably is synchronicity (or even just a major coincidence
)
Again a couple of months ago, I was contacted by someone off another forum I belong to about coaching. She is a fellow coach. We have been working together now each week on some areas, and it turns out we are on very similar paths right now. There are similarities in our background that could NEVER have been uncovered from reading the forum.
It's as if the universe or whoever brought us together to support each other on a 'journey' we are both undertaking right now. Coincidence? Synchronicity? You decide.
