I was living off-grid. had no lights. it was a dark night. i heard a steady, rapid chirping in my driveway. sounded just like a loose fan belt. was hovering about 2-3 feet off the ground. no lights, no visual. i went out on the porch, about 50-60 feet away. when i yelled out “who is that?” the object ascended vertically, slowly, to about 25-35 feet. then it slowly departed horizontally at the same altitude and went into the forest. i never encountered again and nobody here has ever experienced this. it shook me up and i couldn’t sleep that night, but i’m pretty sure it did not adversely affect me.
