Duke of Zhou's Interpretation of Dreams

I. Origin and Historical Evolution of Versions
"Duke of Zhou's Interpretation of Dreams" (Zhou Gong Jie Meng) is not a single work written at one time or place; it has undergone a long process of evolution, loss, and reorganization throughout history:

The Three-Volume Song Dynasty Edition (Lost)
This book was first recorded in official documents in the "History of Song: Treatise on Literature," where it was listed as consisting of three volumes. Unfortunately, this officially recorded version has been completely lost since the Yuan Dynasty.

Surviving Dunhuang Manuscripts (Three Kingdoms to Tang Dynasty)
Modern archaeologists discovered precious fragments of the "Duke of Zhou's Dream Interpretation Book" among the Dunhuang manuscripts. These fragments include a preface, the main text of the first sixteen chapters, and the table of contents for the seventeenth chapter.

Dating: The preface of the fragment begins with the story of the ancient sage-king "Yao" but ends with the death of "Sun Jian," the ancestor of the Wu Kingdom during the late Han and Three Kingdoms period. Therefore, academia presumes this version was compiled around the Three Kingdoms era. The actual physical writing of the Dunhuang manuscript is dated to the reign of Emperor Yizong of Tang.

Complete Dunhuang Version: Another complete scroll titled "Newly Collected Duke of Zhou's Dream Interpretation Book" exists among the Dunhuang documents. The preface mentions "now compiled into over twenty chapters," indicating it was compiled later than the aforementioned Three Kingdoms fragment.

Modern Popular Editions
The editions of "Duke of Zhou's Interpretation of Dreams" commonly seen today in markets, fortune-telling stalls, or online differ significantly in chapter titles and content from the Dunhuang fragments. However, modern popular editions still retain some ancient charms and interpretive logic, showing a degree of lineage connecting them to the ancient texts of the Tang and Three Kingdoms periods.

Integration of Modern Elements
To keep pace with the times, some modern editions have boldly integrated modern objects into the traditional framework, such as airplanes, spacecraft, overpasses, cinemas, mobile phones, and computers. The analysis of these modern items is not fabricated at random but is derived from traditional dream interpretation theories like "analogical reasoning" and "categorical symbolism," making the system more progressive for the current era.

II. The Fifteen Categories of Dreams
Folk dream culture categorizes human dreams into fifteen detailed types based on their causes, states, and prophetic nature:

1. Direct Dreams (Zhí Mèng): What you dream actually happens in reality; a direct correspondence.
2. Symbolic Dreams (Xiàng Mèng): Dreams filled with symbols and metaphors (e.g., dreaming of fish symbolizing wealth) requiring translation.
3. Causal Dreams (Yīn Mèng): Dreams triggered by a strong inner obsession, cause, or unfulfilled wish.
4. Thought Dreams (Xiǎng Mèng): Products of intense focus or "what one thinks by day, one dreams by night."
5. Refined Dreams (Jīng Mèng): Stable dreams occurring when one's spirit is clear and vital energy (Qi) is balanced.
6. Character Dreams (Xìng Mèng): Dreams reflecting a person's innate disposition, character, or temperament.
7. Interpersonal Dreams (Rén Mèng): Content centered on social relationships or interactions with relatives and friends.
8. Sensory Dreams (Gǎn Mèng): Dreams triggered by external climate changes, environmental sounds, or physical stimuli.
9. Seasonal Dreams (Shí Mèng): Reflections of seasonal changes and time transitions on human physiology and psychology.
10. Inverse Dreams (Fǎn Mèng): Dreams that are the opposite of reality (e.g., dreaming of an ill omen leads to good luck).
11. Borrowed Dreams (Jiè Mèng): Using unrelated things to hint at or entrust a future omen.
12. Entrusted Dreams (Jì Mèng): The fortune or misfortune of others is entrusted to one's own dream (e.g., parents dreaming of an event happening to their child).
13. Transformed Dreams (Zhuǎn Mèng): Dreams that undergo massive reversals, distortions, or illogical changes during the process.
14. Illness Dreams (Bìng Mèng): Physiological dreams caused by disease, organ imbalance, or Yin-Yang disharmony.
15. Ghostly Dreams (Guǐ Mèng): Nightmares involving ghosts, spirits, deceased relatives, or extreme fear.
    (Some texts also categorize pleasant dreams that leave one refreshed upon waking as "Beautiful Dreams.")

III. Why Attributed to the "Duke of Zhou"?
To understand why this book is named after him, one must understand the origin of the Duke of Zhou (Zhou Gong Dan) as the "God of Dreams":

The Allusion of "Dreaming of the Duke of Zhou"
The Western Zhou statesman, Duke of Zhou, was the political and moral idol Confucius admired most. Confucius spent his life trying to restore the Rites and Music system established by the Duke of Zhou.
In his later years, seeing the world in chaos and the decline of the ritual system, and feeling himself aging, Confucius lamented in the "Analects":

"Extreme is my decay! For a long time, I have not dreamed as I used to of the Duke of Zhou."

Deification as the "God of Dreams"
Confucius's statement was originally a metaphor for his failed political ideals. However, as this phrase spread among the common people, the public directly linked the "Duke of Zhou" with "dreams."
In folklore, the Duke of Zhou was gradually deified. It was believed that before a major event or a change in fate occurred, the Duke of Zhou would enter a person's dream at night to provide guidance. Thus, he was revered as the "God of Dreams," and "dreaming of the Duke of Zhou" became a Chinese euphemism for sleeping.

Subsequently, when various folk books on dream divination and future prediction were compiled, authors attributed them to the well-known "God of Dreams" to increase authority and mystery. This is the true origin of the title "Duke of Zhou's Interpretation of Dreams."
