This literally just happened and I made an account to post it.
I was at my old Primary School and I thought I was the only one there. After a couple of minutes of chilling out I see a boy walk past on the other side of the playground. He's about my age and wearing a dark blue hoodie and tan jeans and he moves to walk around a corner.
I go to follow him and I turn the corner but he has literally disappeared.
I obviously am scared and confused, and spend about two minutes standing there shaking. I'm advancing forward, wondering if I was just slow to follow and if this kid was smoking weed somewhere. So I start checking spots as I nervously walk past. I pass a dead-end and see the kid again, walking towards the dead-end. I do a double-take. Gone.
By now alarm bells are ringing in my head so I run to a friend's house--he lives next door to the school. I see that he is having dinner so I talk to his cat without disturbing him and make my way back onto the school.
I see the boy looking directly at me through a wall of tires so I get out my phone and take a video. I can see him on my phone. I say "There he is, behind the tires". I pause the recording and start advancing towards the tires, but he ducks out of sight. I continue filming.
I'm at the tire wall now and nearby is some concrete ground with a snakes and ladders board painted on. While I do not see the boy, some small stones are audible and I myself see them land as if thrown carelessly at me. By now my phone is shaking.
I make my way around the school, still filming, but my phone runs out of space. The moment I stop filming, I hear a loud crash directly behind me so I sprint towards my friend's house again and climb over the metal fence that the school erected.
I'm now tapping on a glass door to try and get their attention when I hear the fence make a noise as if it's being climbed over. I'm eventually let in and explain my story to my friend and his mum. I show them the video of the tires--"There he is, behind the tires"--but the boy isn't on the video. There is empty space where his head was looking at me.
My friend is spooked and his mum is interested in the story. Friend's dad drives me the short walk home.
What the hell just happened.
