Someday I will write this whole story down, it is like some bizarre ghost story.
I was a chaperone for a Girl Scout camping trip when I was 16 (the kids were about 5-9 years old). I had a cabin with six kids I was in charge of at night, and helped out during the day.
Night one, one of my kids had a bit of a developmental issue. I wake up to her leaving the cabin. I chase after her thinking she is going to the latrine, but she's sleepwalking. I'm out in the dark barefoot trying to coax this creepy kid back inside when I hear something big out in the woods. I grab the kid and she starts screaming like an infant and goes stiff. I carry her back inside, everyone in my cabin is awake, I don't sleep the rest of the night.
Day two: Sleepwalker is moved to another cabin. That afternoon, when I'm walking the kids back from the latrine, sleepwalker and another kid sneak away from the group. I realize they are gone, get help, find kids fifteen minutes later. Back at camp, they start telling scary stories about their sneaking away, saying it was the "KittyCow" who lives in the woods.
Night two: Wake up and its gotten cold. Get up to close the windows and shutters and see a light in the woods, like someone has a lantern. It "walks" to a point in the woods, then stops. I stay still in the dark and watch it for a long while, about to shrug it off when the light moves again, coming around and going down the side of the cabin, closer, but not close enough to see who is carrying it. I realize its heading to the window by the kids bunk beds, sneak over and close the window and shutters. The light stays close on the other side of the shutters for a long time before moving on and disappearing.
Day three: Tell adults about light. They dismiss it as probably a ranger checking the campsite.
Kids by this time are totally freaking each other out over KittyCow. Literally starting to be afraid to leave the craft area in broad daylight because KittyCow might be there. There's all sorts of weird KittyCow stories. That afternoon, we find out a bear broke into another camp and ate food, so in addition to a real threat, we think that may be the origin of KittyCow.
Night Three: I stay up listening to music to see if the lights will come back. About 1 am, I see it coming by again, again walking to a point in the woods and waiting. Around 1:30, it starts closer to the cabin. As its walking around the side, I hear one of the other chaperones start to yell "hey, who is that? Who's out there?" The light cuts off. I yell back to the chaperone that I saw it too, what should we do? I'm terrified at this point.
The chaperone tells me to bring my kids over to her, holding hands. We all cram in one cabin, and a bit later a thunderstorm starts. For another night I basically don't sleep.
The next day everyone sort of laughs it off again, sort of saying we weren't seeing anything, that maybe it was heat lightning or the kids were playing with flashlights and we saw them reflected. I'm so sleep deprived it hurts and I'm hearing popping noises.
I end up being paired with another chaperone and we go for a hike with the kids. It's all foggy in the woods, and the kids are really strung out between the excitement the night before, which they blame on KittyCow. Out in the woods the kids start claiming they are seeing KittyCow everywhere, sneaking up on us.
I can't tell you now how weird and terrifying things got then. You had this Silent Hill fog, the kids are freaking out over every tree, screaming KittyCow is coming to get them, and I'm barely held together on no sleep, convinced myself that some weirdo has been creeping around our camp.
Things literally devolve into mass hysteria, the kids are literally falling to the ground screaming and sobbing, and the other chaperone LEAVES. She just books it out of the forest back to camp while I am coaxing, pulling, and CARRYING screaming children out of the mist.
I have never and will never experience anything as creepy and terrifying as that afternoon in the woods. While nothing happened, its haunted my dreams since then.
