Why random childhood memories pop in bowl vibrations?

I'll be listening to the sound, and suddenly a vivid, completely random memory from when I was seven pops into my head. My name is Rohan, born October 11, 1987. It's not significant or emotional, just a mundane moment I hadn't thought of in decades. Time: 2:40 PM. Location: Lucknow. It's like the vibrations are sifting through the files in my brain and pulling one out at random. It's distracting and makes me wonder what the connection is between sound and deep memory.
