Because of their association with UFOs and high technology, hairy dwarfs are generally kept separate from another miniature Bigfoot-type creature, the proto-pygmy, a creature that has behaviors more typical of a mystery primate or primitive human. Sometimes hairy dwarfs are linked with reports of larger hairy humanoids that are either reported as occupying UFOs or are seen in the same areas as UFOs and only when a current UFO scare is underway. Some of these larger hairy humanoids are quite bizarre, including even such things as werewolves.
The Incident[]
Witness sketch of the entities involved in the Caracas Incident
On December 22, 1954 - two men in Caracas, Venezuela were attacked by four hairy dwarves wearing loincloths while travelling on the road to nearby Petare. These creatures emerged from a spherical UFO hovering 6ft above the road - and when one of the men tried to confront one of them, it pushed him back and sent him flying 15ft through the air. The creature leapt at him and started clawing at him, while his terrified friend fled the scene to go get help. Before this help could arrive, however, one of the dwarves shone a beam of light at their victim - stunning him so that they could swiftly pile into their bizarre aircraft and quickly vanish from the scene. There would be at least two other reports of hairy dwarves attacking random hunters and truckers all across Venezuela that same year.
I think that the entities shown in the Slitting Mill case might've been of the same variety as the ones seen in Caracas. They are diminutive hairy humanoids, and are associated with the UFO phenomenon. The reason that I claim that the Slitting Hill creatures are connected with UFOs is because of the presence of missing time in the witnesses' memories - which is something that is often associated with alien abduction reports. It is also interesting to note that folkloric monsters such as Boggarts and Bogles from that area match the descriptions of hunch-backed hairy dwarves. Perhaps these hirsute aliens have been visiting the English countryside for longer than we may like to acknowledge?
