Nine causes are historical dream theory, not a modern model
The Gǎnbiàn chapter in Volume Two of Menglin Xuanjie sets out nine causes: qi excess, qi deficiency, pathogenic influence, physical constraint, emotional overflow, direct correspondence, symbolic analogy, reversal, and supernatural attribution. It brings together possible conditions of dreaming with ways of narrating and interpreting dreams. It is not a modern psychology, medical, or paranormal classification.
The first five: how the text imagines dreams arising
Qi excess, qi deficiency, and pathogenic influence belong to historical body and illness theories and are presented here only as cultural material. Physical constraint attends to pressure, posture, and sensation during sleep. Emotional overflow attends to intense joy, anger, fear, worry, grief, longing, and shock. These categories invite readers to notice bodily comfort, sleep conditions, and recent emotion rather than looking up one object alone.
The last four: how the text reads dreams
Direct correspondence presents some dreams as directly matching later accounts. Symbolic analogy reads through comparison and imagery. Reversal cautions that surface fortune may be turned around. Supernatural attribution is a historical way the text sometimes accounts for dreams. These are traditional narrative frameworks, not confirmation about the future, spirits, or real-world outcomes.
Physical constraint: sleep conditions can matter
The chapter gives examples of a mouth holding something, a foot being obstructed, a head slipping from a pillow, or pressure at the waist. It connects these sensations with dream scenes such as difficulty speaking, difficulty walking, falling from height, or seeing a snake. Such details are useful sleep context to notice, not fixed answers for a dream symbol.
Emotional overflow: strong feeling can enter a dream
The text lists heightened joy, anger, fear, worry, grief, longing, and shock as dream backgrounds. Noting recent emotion may help someone reflect on a dream’s movement, but it does not replace professional mental-health or medical support.
A note from Yuanji: relevant context beats a pile of symbols
The Yuanji chapter favors focused reflection over broad analogy and shorter explanation over accumulated commentary. More symbols do not automatically produce a better interpretation; the context, change, and feelings that truly belong to the dream usually matter more.
Historical theory note
This page discusses historical Chinese ideas about qi, bodily condition, and supernatural attribution for cultural and intellectual history. It is not medical diagnosis, treatment advice, or a factual claim about supernatural events.
