They’ve shut off the electricity. There are no factories or busy intersections. And still the English village of Woodland remains at a loss regarding the mysterious “hum” that has plagued the small town from midnight to 4am each night for nearly two months. Residents describe this hum as a vibration similar to the whir of a car engine, reports the Telegraph; one says it's so strong at times that it shakes bed frames. "It's not tinnitus, that's a high pitched sound and this is very low,” one resident explains. “If I put my fingers in my ears it stops, so I know it's not in my head.”
"In certain areas of the house you can hear it more loudly," she continues. "It is definitely from outside, it's in the air, all around, very faint." The 300-person town isn’t the first to experience “the hum.” In the ‘70s, thousands in Bristol suffered nosebleeds, sleeplessness, and headaches from what they described as a similar rumble. Eventually Bristol's hum subsided, but it has never been explained—though it was featured on the X-Files. (More mystery stories.)
