I ran into a silent stranger at night

When i was 14 i used to walk down to the local elementary school late at night during the summer to sit on the swings and get some fresh air. id usually be there around 2 or 3 in the morning.

One night i kept hearing a strange noise coming from the middle of the playground field, so i went to investigate. it was pitch black and i had no light source except the lights from the school 150 or so yards behind me.

When i got to the edge of the field i saw what looked like a person sitting in the grass, so i pulled out my shitty flip phone to try to provide some extra light which didn’t help at all. but it appeared the person was sitting on the grass rolling around. so i yelled “is someone there, are you okay?”

They didn’t answer to i turned my phones camera on and used the flash to snap a picture. the light from the flash provided me a second to see a woman sitting in the grass holding her feet and rolling around making almost no noise.

I didn’t know what to say or do, so i turned around and ran all the way home, still have no idea who she was or what the fuck she was doing.
