According to Galnet, "Walking Sam is an ancient being, according to Native American lore, tied in closely with spiritual beings known as the "Stick Indians." Stick Indians are the shadow people or dWark people. Even in childhood, children hear legends of these dark forces, demonic presences that will stalk reservations and try to lure unsuspecting victims to their doom. They have a cloud of death that hangs over them and follows them, no matter who they are stalking.You may know if one is nearby because you will hear it whistling to you. If you follow the whistling, these beings may have the ability to paralyze you, hypnotize you, or simply drive you insane. If you were to disrespect them somehow, they would hold the grudge and seek out vengeance upon you, no matter the cost. Some tribes still regard these beings with such fear and respect that they do not speak of them, and thus their full legend isn't known outside the indigenous communities. We do, however, know that Walking Sam is believed to be one of those beings and that he's one of the most powerful of them." This is a major scary creature for The Lakota Nation in South Dakota. Is this tall whistling nightmare something that's mystery can be cracked?
