Am Fear Liath Mòr (1900, Ben MacDhui, Scotland)

Two men were chipping for crystals on the slope of a mountain, when they suddenly became aware of a giant gray-colored ten-foot tall figure walking towards them. The figure was momentarily lost from sight in a dip on the slope, and then the witnesses became extremely terrified and ran away from the area. There is a rich history of sightings of phantasmal giants on this Scottish mountain, so much that a name has been given to the creature - Am Fear Liath Mòr or the Grey Man.

Ufonaut (1900, Kuhmo, Lentiira, Finland)

Four children had gone into the swamp and wooded area in order to collect cloudberry. The older children were supposed to keep an eye on the younger ones. An adult had also stayed close by, at the foot of a large pine tree keeping a close eye on the children. Suddenly she became aware that the children were nowhere to be seen; terrified, she ran to the village and immediately a search party was organized and a thorough search was conducted for days, however no trace of the children was found. However weeks after their strange disappearance, the children suddenly appeared again, standing under the large pine tree. After being interrogated by village elders, all the children could remember was that they were approached by some “friendly people” and invited to fly onboard a “device in the air.” According to some of the children, they were able to look down and see the Earth below them. The children were in good health and the adults could not explain how they had gone without food or shelter in the woods for several weeks.

Dwarves (1900, New South Wales, Australia)

A girl was taken at night from between her sisters as they slept beside a billabong, by little humanoid creatures with leathery skin. They took her underground and covered her in animal fat. She couldn’t see them because her eyes were covered with the fat but she could hear them. She said they just made guttural noises. She was there for a couple of hours, when she started to hear people calling out her name. She began clawing at the tree roots she could feel above her and broke through; she could just make out light and stuck her arm up out of the ground. A man calling out for her ran away as he thought the arm was “from something evil.” He came back with her family and they had a tug of war to get her out. Once they did, they built a big bonfire above the spot.
