Why is it that whenever i think about someone, something, I see that in a few moments?

I have libra sun, cancer moon, cancer ascendant. Today, I was thinking about one of my friends and how I haven't talked to them in a while, then I see them! Or even think about a song in the radio, then that's the song that plays next. <--i was listening to everything the dj was saying and he didn't mention anything about the song I was thinking about
