On a rainy night, 11 guests of various identities were forced to gather in a suburban motel. An unknown commonality connects them and leads to an irreversibly tragic ending… This is the opening scene of the famous film “Identity” directed by James Mangold.

At the beginning of the movie, there is also a scene that seems to be unrelated to the main line: a murderer with a tragic childhood experience who killed six people in a row on his birthday on May 10, was discovered by a psychiatrist on the eve of his execution and wrote a book Strange diary, a hearing was held urgently… The sight returned to the previous hotel. Among the 11 guests on the rainy night, female stars, young men, prisoners, middle-aged couples, young women and children died one after another in a strange manner. At the same time, they also found countdown-like number plates (No. 10, No. 9… …). Then, the driver Edward was woken up in the hotel and saw his psychiatrist, and the biggest mystery of the whole play was also revealed. Through the conversation with the doctor, Edward learned that he was not the real Edward, but a murderer inside the body. One of the eleven split personalities, and the remaining personalities hide the murderous personality who once committed murder. Edward, who represented justice, was ordered to return to the personality hotel in danger, eliminated the fake police personality representing violence, and finally saved the woman who represented kindness, and left the terrifying personality hotel…

Let’s talk about a core concept in the film – split personality. Schizophrenia, scientifically known as Dissociative Identity Disorder (DID), in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V) in the United States, the diagnostic criteria for split personality are as follows: presence The disintegration of two or more identities characterized by distinct personality states may be described as an experience of possession in some cultures. Disruption of identity involves a marked disruption of self-formation and sense of self-control, accompanied by changes associated with affective, behavioral, consciousness, memory, perception, cognition, and/or sensorimotor function. These signs and symptoms can be observed by others or reported by the individual. There are recurring gaps in recalling everyday events, important personal information, and/or traumatic events that are inconsistent with ordinary forgetting. These symptoms cause clinically significant distress or result in impairment of social, occupational, or other important functioning. The barrier is not part of a widely accepted cultural or religious practice. NOTE In children, these symptoms are not better explained by imaginary playmates or other fantasy games. These symptoms cannot be caused by the direct-loading physiological effects of a substance. (For example, amaurosis or disorganized behavior during alcoholism or partial onset of other body disorders.) In layman’s terms, split personality is the feeling that several different souls are inhabiting one’s body; At different times or scenarios (or after being stimulated), certain personalities will wake up and “control” the body’s initiative, and “they” also have their own identities, character traits, and behavior habits. Moreover, the subsequently derived personality may inherit some of the memory of the former personality, but the former has no impression of the latter.

The characteristics of clinical symptoms and the course of the disease in general DID patients are considered to be closely related to the early trauma experience, and acute stress response and post-traumatic stress disorder can be seen clinically. For example, the murderer in the movie “Deadly ID” is due to his tragic childhood past (the mother was unable to raise him and often beat and scolded him, and the father was absent from his life for a long time), which caused his tragic situation of split personality. The eleven personalities split in the film also reflect his various pasts or expectations from the side: Edward the driver represents his inner sense of justice (superego), middle-aged couples are the expectations of his ideal family, The woman who planted the orange tree is his projection of the ideal mother… It is true that split personality is a very rare disease in our lives, but we can still learn from the movie: the family education that everyone receives from childhood is It is very important that if the parent’s care is lacking for a long time in the process of a child’s growth, even if it does not lead to serious consequences such as the formation of a split personality in the child, their minds are certainly not very sound, which is not conducive to their health and peace of mind. growing up.
