Oo Lullabies(2014)

Oo Lullabies is an Indonesian horror film rooted in the traditional lullaby "Oo Nina Bobo." Years after his entire family is murdered in their home, a traumatized boy descends into mental instability. Haunted by fragmented memories, he becomes convinced that their deaths were no accident—that a demon orchestrated the massacre and now returns to complete its dark work. As the boy's grip on reality fractures further, the line between psychological breakdown and supernatural terror blurs. The film weaves folklore and psychological horror into a chilling exploration of grief, trauma, and the supernatural forces that may lurk within both the mind and the shadows of home.
