Unusual sound like a large invisible object rising from the ground into the sky; disturbed all dogs in neighborhood.I was walking my dog down my street and heard a loud noise, hard to describe, sort of like an engine or a huge compressor of some kind, starting at ground level about 1/8 mile in front of me, then as it grew louder, it also rose toward the sky, very weird. The air felt charged again, hard to describe. The sound grew louder until it seemed like it was very high above me, then faded quickly into the distance. Immediately after it stopped, all the neighborhood dogs went crazy, even from inside houses I could hear them barking. My own dog acted confused when he heard it, then also started barking when it stopped. I got the sense that there was something in front of me making the noise even though I couldn't see it, and that it simply rose up and flew away. When I returned from my walk, my mom asked me what the sound was, she thought maybe air brakes on a large semi truck. Though the sound had that kind of quality to it, it was much louder and went straight up and no vehicles were on the street that could have made that sound. It's something I have never heard before.
