Seeing this, most readers should have understood that the heroine is a split personality patient, and Wen An will share the information about split personality with you briefly.

Split personality, also known as dissociative identity disorder (DID), or multiple personality, is a type of mental illness. It's not psychosis, it's not hysteria, it's not schizophrenia. Psychosis and hysteria all have delusions, visual hallucinations, and auditory hallucinations, which simply means that patients imagine a lot of people or things or things that do not exist in reality; Schizophrenia is a more serious mental illness, commonly known as "neurosis" by ordinary people, which I don't need to talk about, and everyone is familiar with it.

DID, on the other hand, is multiple personalities, a split personality, not schizophrenia. It is like having multiple souls in one body, each with its own set of spiritual systems. It's also like a car, with several drivers, each of whom is a different individual. But there is only one car, so the drivers have to take turns.

For DID patients, when each soul takes up the post, he is normal and independent, but because he may not know when, it will be the turn of another to take up the post, so the previous soul will have temporary amnesia, memory fragmentation and other symptoms.

DID is caused by traumatic stress syndrome caused by mental repression in childhood, resulting in unsound mental development, or traumatic stress syndrome caused by major blows. It is a defensive form of self-preservation, in which the main personality separates itself from a stronger successor personality to protect itself. In the view of the psychoanalytic school, the essence of multiple personalities is the separation of mental processes, part of the behavior and experience are maintained separately, there is no communication between each other, and the successor personality is usually aware of the existence of the subject personality, but the subject personality is often not aware of the successor personality.

However, it is not absolute, and there are also subject personalities and successor personalities who are aware of each other's existence and can communicate. This kind of communication, sometimes manifested as self-talk, sometimes just a conscious exchange in the brain, without speaking, two personalities chatting in one brain. There was a case where a girl could separate 6 personalities, and each personality could communicate with each other, as long as she closed her eyes for a while, she could seamlessly switch personalities. There is also a movie in which the two personalities split up can also fight each other, and the audience seems to be fighting themselves. Therefore, the split personality is not as some readers think, the main personality and the successor personality are absolutely not interconnected.

But having said so much, from the concept of split personality to the present, most of this disease exists in film and television dramas, but real cases are very rare, and the authenticity also needs to be verified. Therefore, there is no absolute conclusion on the phenotype of this disease. Wen An can only make a reasonable deduction after consulting a large amount of information.

But a basic principle is that multiple personalities are not schizophrenia, and when a personality occupies the body, he has independent and normal thinking. But there may be differences in temperament, temperament and even specialties between different personalities, for example, one personality can sing, the other can't at all, one personality can swim, and the other can't at all. Moreover, a foreign doctor named Linders has done research, and the split personality will also affect the endocrine of the main personality, which is an interesting phenomenon in physiology. Therefore, the heroine of this article is a split personality and is not inconsistent, but because she is a psychotherapist by profession, it is easier for her to dissociate two personalities for self-protection.

So readers and friends can now look back at the article, Wen An has left a lot of interesting foreshadowing when he first wrote it, maybe if you look at it again, it will be a completely different interpretation. Thank you.
