Most men I know put dreams in the same mental drawer as astrology. Not hostile about it, just uninterested, the sort of thing other people find meaningful.
Which is why I want to show you a chapter of the Huangdi Neijing, the foundational text of Chinese medicine, that is entirely about dreams.
Not as omens. Not as messages from the dead. As clinical information. The chapter is Ling Shu 43, 淫邪发梦 (Yín Xié Fā Mèng), roughly “Pathogenic Excess Generating Dreams,” and it reads like a diagnostic table. This state of the body produces this kind of dream. That state produces that kind.
It was written down about two thousand years ago by physicians who could measure nothing we can measure. No EEG, no sleep lab, no way to see REM. What they had was an enormous number of patients and centuries of accumulated notes.
I grew up in a family rooted in both Chinese and Indonesian traditions, where dreams were treated as information about the body and not only about the psyche. It took me a long time to go back and read what the texts actually say rather than what the wellness internet says they say. The real thing is stranger and more specific.
The Model
The chapter states its theory before the list, which I like. Something enters the body, finds no fixed place to lodge, spills into the organs, travels with the circulation, and the memorable phrase, 与魂魄飞扬, causes the Hun and Po to fly and scatter. The person lies down unsettled and dreams a great deal.
That’s the whole model in a sentence. Dreams proliferate when something in the system has nowhere to settle.
The Twelve Excesses
The chapter comes in two halves, which almost nobody quoting it mentions. Twelve states of excess (盛), treated by draining. Then fifteen states of insufficiency (不足), treated by tonifying.
The excesses:
Yin qi in excess, you dream of wading through great water in fear. Yang qi in excess, a great fire, burning. Both, mutual killing. Excess above (上盛), flying. Excess below (下盛), falling. Extreme hunger, dreams of taking. Extreme fullness, dreams of giving. Liver qi in excess, anger. Lung qi in excess, fear and weeping and soaring. Heart qi in excess, much laughing, and dread. Spleen qi in excess, singing and music, and the body heavy and impossible to lift. Kidney qi in excess, the lumbar spine splitting in two.
Sit with a few of those.
Flying and falling are treated as a question of direction, not psychology. Excess above, you fly. Excess below, you fall. Two of the most universal dream experiences in the species, and the Neijing reads them as where in the body things have piled up.
Hunger and fullness are named explicitly. Very hungry, you dream of taking. Very full, you dream of giving. The text is plainly asserting that the state of your digestive system on a given night shapes the plot.
“The body heavy and impossible to lift.” Every man who has had the dream where he can’t run, where his legs won’t answer, recognizes that instantly. It’s filed under the Spleen, the system governing transformation and the sense of physical substance.
The Fifteen Insufficiencies
The second list works by location. A counterflow qi lodges somewhere, and each place produces its own imagery.
Heart: hills, smoke and fire. Lung: soaring, and strange objects of gold and iron. Liver: mountain forests and trees. Spleen: great marshes, ruined houses, wind and rain. Kidney: standing at the edge of an abyss, submerged in water. Bladder: wandering and travelling. Stomach: eating and drinking. Large Intestine: open fields. Small Intestine: crowded towns and busy thoroughfares. Gallbladder: fighting and litigation. Neck: beheading. Lower legs: walking but unable to go forward. And the bladder region: urinating and defecating.
That last one should stop you, because it’s checkable against your own life. Every man reading this has had the dream where he finally finds a bathroom and something is wrong with it, and has woken up needing to go.
The classical mechanism isn’t ours. But the observation underneath it, that the bladder writes itself into the plot, is one anybody can verify, and somebody wrote it down two thousand years ago.
A third list, in Su Wen 80, covers organ deficiency with seasonal variants. Kidney deficiency: boats and drowning people, and in winter, lying submerged. Lung deficiency: white objects and bloodshed; in autumn, battles. Spleen deficiency: not having enough to eat, and in late summer, building walls and roofing a house.
I find that last one oddly moving. A depleted digestive system dreams of construction, of building the shelter it can’t currently provide.
Now the Hard Part
Here I have to be very clear, because this material gets abused, and men who are skeptical of it are skeptical for good reasons.
A dream is not a diagnosis. If you dream about water, you do not have a kidney problem. There is no study validating these mappings, no trial, nothing resembling a controlled test. Any practitioner telling you what your organs are doing based on last night’s dream is making a claim the evidence does not support, and I’d be careful with anyone selling on that basis.
The system itself is less tidy than it looks. When researchers reviewed how Chinese medicine actually classifies insomnia across 103 studies, they found 69 distinct patterns in use with overlapping symptoms. Even the dream lists don’t fully agree across chapters.
So what’s it good for?
The underlying claim is the valuable one, and it’s correct. The real assertion isn’t “water means kidneys.” It’s that the body’s physical state on a given night participates in what you dream. Hunger, fullness, a full bladder, heat, cold, pain, position. Modern sleep research supports that comfortably, bodily sensations get woven into dream narratives, and the bathroom example is something almost every man has personally verified.
That’s a genuinely useful idea, and it runs opposite to how most of us think. We treat dreams as purely psychological. The Neijing insists they’re also physiological. Both are true and only one is currently fashionable.
And it changes what the question is. Most dream interpretation asks what a dream means. The Neijing’s question is better and considerably more male-compatible: what was my body doing last night?
Recurring dreams of being unable to move, in a man who’s exhausted by day. Recurring anger dreams, in a man waking at two in the morning grinding his teeth about work. Those aren’t diagnoses. They’re patterns worth noticing, and they connect the night to the day in a way that usually turns out to be informative.
How I’d Actually Use It
One line each morning about the dream, one line about the body: what you ate and when, how the day went, whether you woke in the night. Look for repeats over weeks and ignore one-offs. Check the boring physical explanations first: late meal, alcohol, hot room, full bladder, new medication. The Neijing would have looked there first, too.
Your dreams are not a report card. But they’re one of the few places the body describes itself without editing, and the men who wrote that chapter were paying closer attention than most of us manage.
