In the creation of novels, the performance of the characters' hidden depressive emotions and the design of extreme behaviors need to take into account authenticity and dramatic tension. The following hierarchical presentation of specific techniques and deep logic： 1. The hidden coding of hidden symptoms 1. Manifestation of Energy paradox -Morning somatization: Design the character to have persistent stomach pain, migraine and other physiological details in the early morning (such as the morning vomiting of Kafka Nakatamura in "Kafka by the Sea") -Conservation of social energy: Arrange for the characters to leave the scene frequently to make up makeup/smoke during the party, and create an emotional buffer through the time difference (refer to Naoko's disappearance in the middle of the banquet in "The Norwegian Forest") 2. Deformation of language topology -Confusion of tenses: Deliberately confuse the time dimension in the dialogue ("It rained last week and it's still raining") -Quantifier alienation: Use unconventional quantifiers such as "three pieces of silence" and "five grams of sadness" to suggest cognitive distortion 2. The symbolic system of compensatory behavior 1. Order forced ceremony -Topological cleanliness: use a ruler to measure the spacing of furniture every day to create the illusion of control -Numerological dependence of numbers: Only page numbers and clock numbers are allowed to appear in a prime state 2. Sensory compensation experiment -Pain calibration: Regularly use different materials (ice, sandpaper, steel wire) to test the pain threshold of the arm -Taste reset: Bring a perfume bottle full of concentrated lemon juice and spray the tongue during mood swings 3. The metaphorical structure of extreme behavior 1. Space deconstruction ceremony -Topology self-destruct: Arrange the room into a Klein bottle model, dismantle and rebuild daily -Map incineration: Systematically burn maps of a specific scale to create cognitive territory collapse 2. Time dimension operation -Clock alchemy: collect second hands to make metal sculptures, each corresponding to an important memory date -Parallel calendar: Use three different calendars to record daily life at the same time to create a time maze Fourth, the narrative strategy of the text layer 1. Weather correspondence system It is designed that rainy weather coincides with the character's efficient working hours, but on sunny days, it is arranged to be trapped indoors "accidentally". 2. Mechanism of food discoloration Let the character experience a specific color fear when cooking (such as sudden inability to handle green ingredients), suggesting an emotional trigger point 3. Book annotation Establish a secret language system at the margin of the character's collection, and use the library classification code to mark the psychological state (such as BF575. D7 represents the depression level of the day) Deep logic construction： 1. Establish a topological mapping of symptoms and metaphors so that every external behavior can be deconstructed into a psychological equation 2. Design reversible details, such as the possibility of preserving reconstruction during self-destructing behavior (shredder documents retain edge integrity) 3. Implanting quantum narrative elements: the character observes the parallel self at extreme moments, leaving room for redemption Precautions： • Avoid linear correspondence between symptoms and behaviors, and build a mesh trigger system • Set up a triple foreshadowing before extreme behavior: materiality (collecting specific items), spatiotemporal (periodic behavior), linguistics (metaphorical system change) • Use negative space narrative: indirectly reflect the abnormality of the character through the confusion in the dialogue of others, such as "You have always spoken with brackets recently" This creative method transforms psychological facts into a literary symbolic system, expands narrative possibilities while maintaining the basis of reality, and makes the character's psychological predicament not only clinically authentic, but also carries symbolic aesthetic value. The key is to establish a unique metaphorical rule system, so that every detail becomes a decodable psychological equation.
