Red car effect.
This happens quite often. This phenomenon is the Baader-Meinhof phenomenon. If you are interested, then you can google it more specifically, but in general, as already mentioned here, a person simply begins to pay attention to the information (name, word, etc.) that he has learned. That is, earlier he would have simply ignored it, but now he notices.
I have this not only with names, but with everything in general. From the latter, I added the song Carla's Dreams - Sub Pielea Mea (Eroina). I listened to her all evening. The next day I had to use a taxi. As soon as she got into the car, she started playing on the radio. A day later, the same thing, only in a friend's car.
Or, for example, I read here about the word "assertiveness". For half an hour I understood Google with its meaning, I remembered it. And people around suddenly began to say this word, which I had never heard from any of them before, and who would even think of talking about assertiveness in everyday conversation? But no.
I think we just don't pay attention to many things, and when we concentrate our attention on this something, we begin to notice it around, although it was there before. We just weren't interested in it)
I've had this twice. Once it was really my friend who hyped that he was even shown on federal TV, and the other that I began to worry very much about a person with one name, that I listened attentively to everything where this name sounds. Maybe this name worries you too? Or rather, its carrier from which it all began.
