sound heard in scotland

Locals in Scotland reported last night that they were awoken by a mysterious sound. This isn’t the first time Scotland had experienced such a sound, as reported can be dated all the way back to 1970 when the first cases began to appear. Surprisingly though, the sound is now making it’s way around the world from places in Europe, to Canada and areas in the United States.  No explanations have been given as to what is producing this sound. Some say it’s earth and others say it’s a warning from god. There is one possible reason though and it’s been caught on tape.
