Joining the community!! Let me talk right away🙇‍♀️🙇‍♀️

This is a story from when I was little, before we moved... I woke up in the middle of the night. My mother was sleeping in the bed next to me. The moment I got up to go to the bathroom... I heard the sound of plates breaking...!? I tried to approach my mother to wake her up, but she wouldn't stir at all. Figuring I had no choice but to go check alone, right after that I heard a child's laughter (estimated to be a little girl around three years old), and I got too scared to go to the bathroom, so I just went back to sleep. After waking up, I checked the plates and none of them were broken... I thought maybe it was the next apartment? (The house at the time was a pretty nice apartment, though) But when I asked my mother, "Did anyone live next door?"... no one lived next door. ...So what was that voice? What was the sound of the plates breaking? It's still a mystery to this day.
