Have you ever had a paranormal encounter?

I wanna post mine. its my sisters' story but I was there. - my sister and I are the oldest of the cousins. We have a 6 year age gap, so I remember one time when she begged my mum to go spend a weekend at our uncles' house. So my mum let us so she can have time to herself. Now, this is an uncle that we dont talk to, my husband has never met him, but i follow his kids on social media and we touch base here and there. His wife at the time was an absolute nutcase. At the time, our cousins and I and we were getting ready to put our toys away and go to bed. My sister was walking around turning off the lights and she stopped and stared outside at the backyard. this was at like 10pm and my 7 year old self was tired and not having it. so I walked up to grab her hand and I swear to God, I saw a little girl in white sitting on the yellow slide staring at us. Deadass looking at us. I dont know WHY or anything, but I remember this little girl standing off the slide, and disappearing as she was walking over to us. I didnt give a fuck about my sister, my cousin, nobody. I booked it up those stairs and yeeted into my bed. I woke up the next day and my sister didnt remember it. I wrote it in my journal so I could show my mum when I got back. I dont know WHAT happened after I told my mum and dad, but my uncle divorced his wife soon after. Im still terrified to look outside at playgrounds to this day.
