Still confused after 20 years about my only ghost encounter

So before the encounter happened I was very superstitious of ghosts didn’t believe in them but there was a sequence of events that happend that night that made it all too real. I was around 7 or 8 years old and I had a friend who was around my age and she was the daughter of my moms friend so we would hang out while my mom and her mom went to the club. I’ve visited this new house they moved into a couple times before, but this day was so insane because we were playing as usual , and then my mom says we’re going to the club, ight so now we’re alone. So in typical fashion I start to play but she says to me “look everytime you guys leave I hear your mom’s name”. I’m like “what do you mean ? “ she like “ it’s a whisper of Brianna Briana Briana and it’s freaking me out “ so I’m like “nahhhh“ lowkey scared but thinking she’s just trying to freak me out. So we play for like an hour, my little sister was with us as well she was like 3 or so, so we started getting sleepy and I was holding my little sister in my arm rocking her and i close my eyes and sure enough I hear “Elijah” in my ear no less than an inch away clear as day I jumped up not like screaming just a subtle jump and I must’ve looked like spooked because I didn’t say anything and then my friend said “ I told you “ she knew exactly what happened like I didn’t even have to say anything , funny enough I wasn’t like scared or had the need to cry I was just like whoa and I stayed up. My mom came and picked us up I told her like I had too bc wtf and she was like oh ok … but I never forget that I NEVER forget that. I’m studying the measurement of sound now and the story revisited me and I’m just like how was a ghost able to say my name so clearly.
