The article aims to present the problems of conflicted memories about mass murders of communists and suspected communist sympathisers in Indonesia in 1965 in the context of unsettled traumatical past and social denial. The author outlines some questions of difficulties in settling the past crimes of the Suharto regime, such as the tangled practices of remembering and forgetting, nationalism and history gaps in history school books, and the inability to shame and to take a responsibility for past crimes. In Indonesia, still the grand national narration is visible, in which the army headed by General Suharto protected the state from the communist treachery. This narration persistently obscures the approximately one million deaths, torture and imprisonment of thousands of people. The tangled memory, social denial and actively generated silence which are maintained by both state and society do not let the Indonesian nation to move forward.
