The phrase "how to save a dead friend" primarily refers to the title of a 2022 documentary film directed by Maroesja Syrojetsjkovskaja. This film is a personal, intimate coming-of-age story about the director and her lover Kimi, set against the backdrop of post-Soviet Russia and its societal challenges. It explores themes of youth, drug addiction, repression, and the struggle for hope amid despair. The film is composed of home video footage and portrays the tragic love story of two young people coping with a harsh environment and personal demons

. If your question is literal—how to save a friend who has died—there is no known method to revive someone who is truly dead. In emergency situations, immediate medical intervention such as CPR or advanced life support may save someone who is clinically dead or in cardiac arrest, but once biological death is confirmed, revival is not possible. If you are referring to emotional or metaphorical "saving"—helping a friend who feels lost, depressed, or "dead inside"—the best approach involves offering support, encouraging professional help, and being present for them. In summary:

• "How to Save a Dead Friend" is a documentary film title about youth and tragedy in Russia

• There is no way to physically save a friend who is biologically dead.
• In emergencies, immediate medical help is critical.
• Emotional support and professional care are key to helping friends struggling with mental health.
