Why does bowl shut off thoughts into eerie empty silence?

When the bowl rings, my internal chatter doesn't just quiet down—it shuts off entirely. My name is Meera, born September 8, 1995. There's no thinking, just a vast, empty silence that's both peaceful and a little eerie. Time: 10:50 PM. Location: Kolkata. I'm not focusing on my breath or a mantra; I'm just absorbed in the sound until it fades. I don't know if this "nothingness" is a deep meditative state or if I'm just zoning out in a new way.
