What is the weirdest coincidence you have ever experienced?

I think everyone has experienced situations where you are thinking about abut a particular thing, it often happens to be a song, and soon after that something happens related to what you were thinking, like for example, the song starts playing randomly on a device you don't control? Do you know what I mean? It can also happen with numbers I believe...

In my case, the weirdest coincidence happened more than a decade ago with a younger cousin. He was a small kid and I remember I was in my room and there was something I wanted to tell him but I guess I was too lazy to yell his name so he could come, but a few seconds later he appeared in my room asking me what was it as if I had yell to him. I was very puzzled because I was completely sure I didn't yell for him but he still came to my room.

I have the feeling there were other similar experiences but right now I cannot remember them. This is the only one that I can clearly remember.

What about you, what is the weirdest coincidence you have ever experienced?
