A biology teacher has reportedly noticed thousands of earthworms on the snow while he was skiing outside Bergen, southern Norway on Sunday, 12 April.
"I saw thousands of earthworms on the surface of the snow. When I found them on the snow they seemed to be dead, but when I put them in my hand I found that they were alive," Karstein Erstad told The Local.
Latest reports suggest that the worms might have been thrown up from a ground miles away, possibly by a tornado.
After the worm rain news was aired on national channels in the country, many others reported witnessing such incidents in Lindås and Suldal, near Bergen.
Erstad claimed that the incident is not new, as there were similar reports of worm rains dating back to the 1920s in the country.
However, with many conspiracy theories doing the rounds, the new phenomenon remains a mystery.
Similarly, many other creatures falling from the sky have been reported earlier.
While more than 20 small fish fell down from the sky at Hatfield in Hertfordshire on 17 May, 1996, thousands of frogs fell on Gibraltar on 21 May, 1921, according to the Independent.
