Did you know Canada.. there is a Canadian folklore about the Windigo. The Windigo is a spirit believed by the Algonquian to take possession of vulnerable persons - often while they are dreaming.
The Windigo has been described in many forms including a hairy giant (similar to the Sasquatch), a shapeshifter and a gaunt, icy, gray skin and bones creature.
Windigos are full of gluttony, greed, and excess - never satisfied after killing and consuming one person, and constantly searching for new victims. And apparently an actual Windigo murder trial took place in Canada around the beginning of the 20th century.
There's actually something called Wendigo(alternate spelling) psychosis - which refers to a condition where sufferers developed an insatiable desire to eat human flesh even when other food sources were readily available.
Windigo has also made an appearance in many tv shows, movies, novels and video games including Stephen King's Pet Semetary, the tv show Supernatural, and the video game Final Fantasy.
