The Zhou Gong lines
齿自落者父母凶 — "Teeth that fall out by themselves: misfortune touching the parents." 齿落更生子孙兴 — "Teeth fall and grow again: the sons and grandsons thrive."
What the Chinese book does NOT have
The contrast is what makes this worth a page. In the Zhou Gong chapter on teeth there is no counting rule, no hand/lap/ground landing rule, no burial switch, no jaw-to-relative map. Teeth dreams carry exactly two verdicts: fallen-and-gone targets the parents; fallen-and-regrown targets the descendants. Meanwhile the whole elaborate per-tooth machinery — the father is the right front tooth, one tooth paid is one creditor, thirty are thirty dinars — exists only in the Arabic books (Ibn Sirin compilation "Teeth," pp. 349–352; Al-Nabulsi's "سن" entry at shamela.ws/book/1217/177, printed p. 180).
Where all three traditions agree
The teeth-falling dream is a family dream in every classical system that wrote about it, not a money dream and not (originally) an anxiety dream:
- Zhou Gong: parents or descendants, depending on whether the teeth return.
- Ibn Sirin compilation: "Teeth in a dream represent the elderly members in one's family" ("Molar Tooth," p. 281) — and the entry's most famous frame is a political one: a Caliph dreams his teeth fall out, the first interpreter says "your whole family will perish," and a second reader (Sa'id bin al-Musayyib) re-frames the same dream as "he will live longer than his peers and outlive all his relatives" (front matter, pp. 12–14). Same dream, same family frame, opposite sign — the oldest recorded interpreter's trick in this literature.
- Al-Nabulsi: "The teeth are the people of the dreamer's house" — the full tooth-by-tooth relative map.
That three literatures with no contact all landed on "teeth = the people in your family" is the one genuinely cross-cultural fact about this dream before psychology got to it in the 20th century.
The age reading: one Arabic book hedges, the other counts years
Al-Nabulsi's first line vs. Ibn Sirin's first line
Al-Nabulsi opens his "سن" entry with the hardest claim the literature contains:
"the tooth (سن, sin) in a dream points to the end of the appointed term (أجل) and the years (السن) written for the dreamer" — a wordplay: sin means both "tooth" and "year of age." The same page then prints the hedge: age-death readings are for the sick or the elderly; the healthy get a different clause. The Ibn Sirin compilation's opening is the mirror image: "Falling teeth in a dream means longevity" — the dream doesn't take years, it means you keep them.هي في المنام دالة على منتهى الأجل والسن الذي كتب له
Thirty, by any unit
The Arabic books share one bizarre detail: the number thirty. Ibn Sirin's teeth entry maps fallen teeth one-to-one onto creditors and debts; Al-Nabulsi's سن page (shamela.ws/book/1217/177) prints a "some say" (وقيل) chain where loose teeth mean either nine-and-twenty or thirty years remaining, or death within thirty days, or a fine of thirty dinars — the same digit doing the work of time, life, and money, because the dream is read as an arithmetical transfer. You will not find this on any Western dream site; it lives on one Arabic page.
Classical textWho actually gets the teeth: pregnant women, elders, the recurrent dreamer
Neither classical book is psychology, and neither mentions stress — but their per-person readings differ in ways that matter if you belong to one of these groups:
If you're pregnant
The Chinese system is the one that reads teeth as offspring directly: 齿落更生子孙兴 makes regrowth a fertility sign, and the chapter's hair/teeth block is part of a body-symbol set the tradition uses for pregnancy and children. The Arabic books have no pregnancy clause for teeth at all — the child reading comes only through the lap-landing line (a tooth falling into the lap = a male child, Ibn Sirin compilation "Teeth"; Al-Nabulsi prints the same trio, with his caught-teeth reversal). Neither system was written for the modern "pregnancy = losing something" reading you'll find on today's blogs; that idea is 20th-century, not classical.
If you're elderly
Al-Nabulsi's age-hedge matters most here: his entry explicitly routes the death-term reading toward the sick and old, while the longevity reading in Ibn Sirin's compilation is aimed at exactly the same demographic — living past your contemporaries. Read together, the two Arabic pages tell an older dreamer the same dream is either his lifespan or his survivability of others. The Chinese block's "parents" line has no age condition at all — it speaks to anyone whose parents are alive.
If you keep having it
Calvin Kai-Ching Yu's Dream Motif Scale survey (Dreaming 22:1, 2012, DOI 10.1037/a0026171) found 39.0% of respondents had a teeth dream at least once, 16.2% recurrently, 8.2% regularly — making it one of the most common body dreams in the sample. Rozen & Soffer-Dudek (Frontiers in Psychology 9:1812, 2018, PubMed 30319507, n=210) then measured the recurrent dreamers: teeth dreams tracked with waking jaw/tooth/gum tension (r = 0.21) but not with psychological distress (r = 0.02). The recurrence literature is the one place where all three classical traditions are silent — none of them treat repetition as changing the reading; the modern data treats the body as the repeating cause.
What a modern reader can actually do with three systems
Nothing here is one dream's true meaning. What the comparison gives you is three different questions the same dream can be asking: the Zhou Gong book asks whether anything grew back (parents vs. descendants). The Arabic books ask you to count and locate — how many, which jaw, did you catch it. The research layer asks one question none of the books asked: how is your jaw feeling this month. They don't conflict; they were answering different people in different centuries. The one claim all three agree on, after a thousand years and three languages, is that this dream is about the people around you, not about you.
