This happened to me back when I was very little and lived in a big house with my immediate family. I was probably around 4-5 at the time. My family and I were having a big celebration, so we had relatives come over. Later that night, only a few of my relatives were left, most of them had gone home. I don't think it was that late at night, maybe around 7-8PM? My mom and the women were in the kitchen preparing more food while my dad and the guys were in the living room drinking, talking and watching T.V.
I remember playing by myself in the living room where my dad and the guys were. I don't remember where my siblings or the other kids were at this time. Anyways, I remember playing with a bouncy red ball, (sounds like a scary movie already. Haha.) and I threw it towards the wall or something and the ball rolled over to our front door. I ran to go get the ball, and once I got there, I heard a voice that called my name through a small decorative window that was in between our closet and the front door. The voice wasn't female or male, it was more like in-between? It was just really weird. The voice said my name spookily like you would in the ghost movies with pranksters. Nobody else was around besides my dad and the other guys in the living room. I thought my siblings were pranking me, so I checked the closet where it was across from the front door and saw nobody in there besides shoes and coats. This freaked me out and I ran back really fast towards my dad and plopped onto his lap. I remember looking back up at the small window, and getting goose bumps. Nothing else ever happened after that, and I don't remember if I told anyone in my family about my encounter either.
Not sure what or who it could have been. I always thought that it was just probably my late Grandma or Grandpa saying hi, but who knows. (That's a real creepy way to say hi to me if it was.;P)
Hope you enjoyed it! Thanks for reading!
