How do you explain synchronicities in life?

Is there an explanation or is this plain coincidence? I think there is some kind of “out there” explanation with Carl Jung’s theory but I would like a different perspective.

For example:
I had been thinking about a new car and contemplating which car go buy, doing research, etc. while I’m thinking about buying a new car, an episode from“King of the Hill” comes on about buying new cars.

I shared that little story with my coworker and she found it funny because as she was testing out her new smoker, an episode from Simpsons came on when Homer got a smoker too.

Another little moment… My bf and I never go out on weekdays but we just happened to be out at night down town. We decide to turn on radio and the song “Downtown” came on and that was the only time we have heard it play since then.

Or when you have a dream and someone else has the same storyline dream….

I would love to hear your experiences or theories,
