On Evil and Dreaming, No. 43

Overall Paraphrase

Minor textual variations exist among surviving copies; the following is read and understood according to the standard edition of Lingshu · On Evil and Dreaming.

🌙 The General Mechanism of Dreams

The Yellow Emperor asked: I would like to understand what happens when abnormal pathogenic qi spreads and disseminates within the body.

Qi Bo replied: When superficial pathogenic qi invades the body from outside, it initially has no fixed place of residence, then proceeds to disturb the internal organs, wandering without settling; it flows together with the nutritive qi and defensive qi (the qi of blood and qi circulating within the human body), and at the same time causes the hun (ethereal soul) and po (corporeal soul) to float and scatter without being stored, which is why a person sleeps restlessly and is prone to frequent dreaming.

If pathogenic qi disturbs the six fu organs, then the qi of the exterior of the body is relatively in excess and the qi of the interior organs is relatively insufficient; if pathogenic qi disturbs the five zang organs, then the qi of the interior organs is relatively in excess and the qi of the exterior of the body is relatively insufficient.

🔥 The Twelve Excesses

The Yellow Emperor asked: Do these conditions of excess and insufficiency manifest as specific images in dreams?

Qi Bo replied: When yin qi is predominant, one dreams of wading through great waters with fear 🌊; when yang qi is predominant, one dreams of great fires burning and scorching 🔥; when both yin and yang are predominant, one dreams of mutual slaughter and combat. When qi in the upper body is predominant, one dreams of flying; when qi in the lower body is predominant, one dreams of falling; when extremely hungry, one dreams of taking food; when extremely full, one dreams of giving things to others.

When liver qi is excessive, one tends to dream of anger; when lung qi is excessive, one tends to dream of fear, weeping, and flying; when heart qi is excessive, one tends to dream of laughing and joy or fright; when spleen qi is excessive, one tends to dream of singing and merriment, with a heavy body that is difficult to lift; when kidney qi is excessive, one tends to dream of the lower back and spine feeling as if they are about to break, with the upper and lower body feeling disconnected.

For the dreams caused by the above twelve "excesses," the ancient therapeutic principle was primarily based on the draining method, draining the excess so that the dreams can cease. (This is explained purely as an exposition of principle and does not constitute medication guidance.)

🩺 The Fifteen Insufficiencies

When reversed qi (chaotic, counterflow qi) lodges in the heart, one dreams of hills and mounds with smoke and fire; lodging in the lungs, one dreams of flying aloft and seeing strange metal objects; lodging in the liver, one dreams of mountain forests and trees; lodging in the spleen, one dreams of hills, great marshes, collapsing houses, and violent wind and rain; lodging in the kidneys, one dreams of being near a deep abyss or submerged in water; lodging in the bladder, one dreams of roaming about; lodging in the stomach, one dreams of eating and drinking; lodging in the large intestine, one dreams of open fields; lodging in the small intestine, one dreams of gathering in city streets and alleys; lodging in the gallbladder, one dreams of contentious disputes, fighting, and self-injury; lodging in the genitals, one dreams of sexual intercourse; lodging in the nape of the neck, one dreams of being beheaded; lodging in the lower legs, one dreams of wanting to walk but being unable to move, or of being in deep underground cellars or enclosed gardens; lodging in the thighs and arms, one dreams of performing rituals, kneeling, bowing, and rising; lodging in the baodan (the region related to the lower burner and bladder), one dreams of urination and defecation.

For the dreams caused by the above fifteen "insufficiencies," the ancient therapeutic principle was primarily based on the supplementing method, supplementing what is insufficient so that the dreams can cease. (This, too, is explained purely as an exposition of principle.)

🧠 In-Depth Understanding

Core Theoretical Principles 💡

• This chapter holds that dreams do not arise without cause; rather, they are a "projection" 💨 of the state of qi movement and zang-fu organ function within the body during sleep.
• The "twelve excesses" pertain to a predominance of zang-fu qi or pathogenic qi in excess; the "fifteen insufficiencies" pertain to relative insufficiency caused by the lodging of reversed qi and local disturbance of qi movement.
• The diagnostic approach is to infer, from the content of dreams, the state of excess or deficiency in the body's yin and yang, upper and lower regions, zang-fu organs, and physical body parts.
• The therapeutic principles carry through the Neijing maxim: "Drain what is in excess; supplement what is deficient." However, the original text addresses only therapeutic principles, not specific formulas or drugs.

Modern Perspectives 🌟

• Modern sleep medicine has found that dreams most commonly occur during REM sleep and are influenced by daytime emotions, memory consolidation, visceral sensations, postural discomfort, and other factors.
• Hunger, overeating, a full bladder, pain, and breathing difficulties can indeed alter dream content, which roughly echoes the ancients' observations such as "extreme hunger leads to dreaming of taking food," "extreme fullness leads to dreaming of giving," and "when pathogens lodge in the baodan, one dreams of urination and defecation."
• However, mechanically mapping specific dream content to the five zang organs one by one belongs to the ancient mode of analogical thinking and empirical summarization. It lacks rigorous scientific evidence and should not be used for self-diagnosis or as a substitute for medical examination.
• Dreams are strongly influenced by culture and personal experience; the same imagery can carry different meanings for different people, and such content should be viewed rationally.

Health Insights ⚡

• Maintain emotional stability before sleep; avoid intense anger, deep grief, excessive excitement, or fear.
• Avoid extreme hunger or overfullness at dinner; reduce vigorous activity and mental stimulation before bed.
• Keep regular sleep schedules and maintain a quiet, comfortable sleep environment to help reduce frequent dreaming and nightmares.
• If troubled by long-term nightmares, insomnia, or excessive dreaming, seek proper medical help rather than self-prescribing "supplementation or drainage" based solely on dreams.
