More Mysterious, Eerie Metallic Sounds — Invisible Conflict? Or Warning?

— “The metallic scraping sound was menacing, foreboding, a screeching unrelenting assault on the auditory senses. All I can say is that the sound seemed like some kind of warning.”

– Earwitness, Sault Ste. Marie, Ontario, Canada

— “We heard this horrible metallic, scraping, synthesizer sound over the  music we were listening to. ...Although we could see nothing, we could  hear and feel something massive rising from the canyon below until it was directly above our heads.”
