Was watching it alone. Second episode is shivering.
Their dead father's spirit came into younger son's body. He was speaking like him. This must be severe case of somebody with psychological disorder. Because of being from conservative background.

Haven't watched but followed this case through media and felt really sad for those kids who became victim of that procedures which they believe that it will bring them back.
