When I was in Yuma AZ for a live fire exercise I'm pretty sure we woke up some old native American spirits. Basically we had finished up with night live fire, the range is cold and most of the company has gone to sleep for the night. I was still up, having a cigarette and just chilling out and enjoying the quiet, and exactly at 12AM/midnight out of nowhere a cacophony of drums and chanting filled the air. A few minutes later, just as suddenly as the music had started, it all ended without a trace, and it was completely silent for the rest of the night, no bugs, wind, birds. Super cool, nobody talked about it the next day, but mostly everyone was fast asleep at that point.
