Mysterious Humming Sound in the Sky recorded in Sweden
According to the witness, he noticed the odd sound while in northern Sweden at what looks to be a snow-covered mountaintop. He says that the humming noise was constant and seemed to almost vibrate the air.
Although he expressed certainty that the hum was coming from the sky, the witness conceded that he couldn’t quite determine from which direction it was emanating as it appeared to be coming from every direction.
He also noted that he has visited the location before and that it is „usually a very quiet place,” what made the odd hum all the more mystifying. Eventually, after nearly an hour, he says, the noise dissipated as if it had „moved somewhere else.”
The sound heard by the witness in Sweden may be connected to the larger mystery hum phenomenon which has been reported in various parts of the world in recent years.
According to coasttocoastam, theories for what may be causing these sounds range from the conspiratorial, such as clandestine military weaponry, air displacement caused by slow-moving huge UFOs to prosaic possibilities involving natural events surrounding the magnetic field of the Earth.
