This video has no back story-- absolutely none. The description reads, "No description available". Just a dog, a dark figure and some whistling. The title of the video says "Possible bigfoot encounter in slovenija (EUROPE)", and that's about it. One commenter posted this about the video:
There are not Bigfoots in Slovenija. I live in North East Italy, not far from Slovenija, and I never heard about bigfoot sightings in that country or in Italy. Maybe there was Bigfoots some centuries ago in these countries, there are many legends about the "Uomini Silvani", the Sylvanic Men, big and hairy wildmen who lived in the forests on the mountains, especially in Venetia and Sardinia, but now they are extinct.
Carl Olinselot says it's a man. See video below:
