I want camping for Halloween how many people got creeped out

I want camping for Halloween in a state park in Illinois. It was very nice but a little bit creepy that carries at night were singing a lot. They were pretty close to the camp. I say maybe 30 to 40 feet away from my camp but really quite creeped me out. It was a hap moon. It was not quite full but is brighter out to see everything I was looking at this tree it look like someone was standing there. I took a picture of it the next day, the funny part it was a root of a tree. It actually does look like a body.
