Last weekend, Karstein Erstad, a biology teacher, was skiing in the mountains outside of Bergen when he spotted thousands of earthworms on the surface of the snow. Erstad said he thought the worms were dead, but he put some of them in his hands and discovered they were alive.
Erstad’s finding made the national news, and after that many other reports of people witnessing similar incidents started to come in. Some of those reports came out of Lindas and Suldal, also near Bergen.
According to BBC, no one is really sure how it rains worms or why, but it is thought that the worms started to emerge from the ground towards the end of winter, and then they were swept by the wind. From there it is thought the worms caught thermals in the mountainous coastline, and were carried up to the sky. Eventually the worms fall back to Earth.
This is not the first time an incident like this has happened. Back in 2011, a PE lesson at a school in Galashiels, which is located in the south of Edinburgh, had to be canceled after it started to rain worms.
Erstad said that similar reports of worms raining down date back to the 1920s in Norway.
