Term for: Simultaneous rare experience/occurrence

I'm talking about a situation where I hear a word, phrase, or telling of an actual experience from one source (e.g., a friend's mouth), and almost immediately hear the exact same word or phrase from a different source such as the radio or TV.

For example, while driving and listening to the radio I might drive around a round-about and at the same time the word round-about comes on the radio in a song. But the word round-about is extremely rare in either fashion.

Is there a term for this experience?

synchronicity:

the simultaneous occurrence of events that appear significantly related but have no discernible causal connection.

(Oxford Dictionaries)

I think the term is coincidence:

• an ​occasion when two or more ​similar things ​happen at the same ​time, ​especially in a way that is ​unlikely and ​surprising:

  • Is it just a coincidence that the ​wife of the man who ​ran the ​competition ​won first ​prize?

  • It was a coincidence that she was wearing a jersey like Laura’s

(Cambridge Dictionary)

This may not be the answer you're looking for, but oftentimes it FEELS like a coincidence or serendipity when in fact you are experiencing a form of confirmation bias known as the frequency illusion:

The illusion in which a word, a name, or other thing that has recently come to one's attention suddenly seems to appear with improbable frequency shortly afterwards (not to be confused with the recency illusion or selection bias).[40] Colloquially, this illusion is known as the Baader-Meinhof Phenomenon.

If it is pleasant, and gives a good feeling, then I suggest serendipity:

the occurrence and development of events by chance in a happy or beneficial way

(Oxford Dictionaries)
