スレンダーマン
During an early 2015 epidemic of suicide attempts by young people ages 12 to 24 on the Pine Ridge Indian Reservation, Slender Man was cited as an influence; the Oglala Sioux tribe president noted that many Native Americans traditionally believe in a "suicide spirit" similar to the Slender Man. Other Sioux describe the "Big Man" as a messenger or sign, warning that society is developing in a dangerous direction.
