What it says. If you feel like discussing/interpreting, go for it.
There was a huge complex of caves in the middle of a desert. There was some school nearby where there were creepy little girls, maybe 8-10 years old, in grey dresses with long blonde/brown hair, they all looked almost identical. Four of them were in some weird agreement with each other and they would run out into the desert at night, running beside each other, trying to leave the prints of a horse as camouflage
Another girl was the bullies' victim and she was hiding in the caves. Only she was trapped there too - tall women were using her energy to power the cave complex, I do not know how or what for. The little girls wanted to burn her alive. She would talk to me when she was in hiding sometimes, I don't know who or what I was, and the tall women would send for her to come back by sending memories to chase her. I remember one where a little girl with sharp sharp teeth would crawl up a tunnel, flicker, then crawl up again, over and over, until the girl left to go back.
Then there was some crazy showdown with more people from the school. A fight inside the desert cave, taking cover behind boulders. A little boy with dark hair was shot and died first but there was a lot of death afterwards. No one had any blood. It was a scene of shadows and dust.
After I was somewhere green, a cottage maybe, in the woods, probably I escaped. The little girl was there, but not for long - she caught on fire suddenly out of nowhere and shrivelled to a crisp.
