Strange sounds are being heard around the world, and no one seems to know where they're coming from. In Sweden, the odd noise sounded like a trumpet. A similar sound was heard in Michigan. In British Columbia, Canada, Dr. Glen MacPherson says he heard a strange humming sound in his home. At first, he thought it was an appliance. “I cut power to entire house and the sound got louder,” he told Inside Edition. He later discovered he was not alone. “This is a worldwide phenomenon," he said.
