This happened to me and a group of friends back in 2010. I live in a rural neighborhood five minutes outside of my hometown which is basically two steps above the middle of nowhere. Some friends had come over for a late night bonfire. We had been out in the back of my house for a few hours, swapping stories and doing dumb things. Suddenly, we heard a strange noise. It sounded like it was coming from an animal, but there was definitely something off about it. It just wasn't quite right. We all stood up and faced the general direction of where it was coming from. My house sits on ~6 acres with a sizable forest directly behind it. A small canal runs between my yard and a pasture for grazing cows. The sound seemed to be coming from the corner of the yard a few feet from where the tree line began. We were all frozen, not saying a word, when the sound stopped suddenly. That's when I noticed how quiet it was. The usual chirping of the crickets, which is nearly constant at night, had ceased. The cows in the pasture had stopped mooing. The quiet was downright eerie. Then, as if someone had flipped a switch, the usual noises began again. My friends and I looked at each other hoping one of us could explain it but came up empty. My brother and cousin came outside not long after and we told them what happened. They didn't believe us and just laughed it off. To this day, I still can't explain it.
