WTW for when you come across an object/idea, then start to notice the same thing in other situations that you may not have noticed otherwise?

For example, I had a friend who bought a new car, then I started noticing other cars of the same model driving around town. I know that that model of car has always been common but I never paid any thought to them until I knew someone who had one.

Another example is that I recently heard a song that I enjoyed, and a few days later noticed a post on social media referencing the same song.

Even since I've noticed that this is something that happens, I've been noticing more examples of it occurring.
