Is there a legend similar to Manbearpig from South Park? Something that's super duper serial you guys??

When I was younger i had a strange experience in upstate NY. I was camping during a Civil War reenactment and I had to use the bathroom in the middle of the night. I was around 7 or 8 years old at the time. the outhouses were a bit of a walk so I tried to wake my friend who was sleeping in the same tent to take me. He was out cold snoring. So I decided to peek my head out to see if it was safe. Being little I didn't ant to get eaten by a bear or some random monster. i looked towards the trail and the coast was clear, but when I looked the other direction that's when I saw them. I saw around 10-15 or so figures through the trees. They seemed to be around 5 feet tall and humanoid in form. They faintly glowing a bluish green. They had one arm outstretched carrying what seemed to be some sort of basket or container, with their other arm they would bend over at the waist and pick something up from the ground and place it in the container, then they would take a few steps and repeat the process. All of them were doing this very slowly. I understandably freaked out slightly and tried waking my friend again. He moaned and grumbled something about needing to sleep and rolled over. I poked my head out again, hoping they would be gone, but they were still there, bending over and putting things in their containers, I sat there staring for a while when my dad's friend came out of his tent. As soon as he did their glowing quickly faded and they were gone. My dad's friend had come out to go to the bathroom. I asked him to take me and didn't mention what I had seen until the next morning. Just wondering if anyone has experience anything similar to this. I always try to rationalize it saying it had to have been a dream or something, but I'm just not sure. My friend remembers me trying to wake him up in a panic, and my dad's friend remembers coming out of his tent to see me standing there with my head poking out of my tent, so I'm not sure. Any info pointing towards similar experiences would be greatly appreciated.

I’m new :>
