Vagina in a dream: what does it mean?
The body part appears in dreams the way other body parts do, and the worry people bring to this page is usually about what it means rather than about the dream.
How do the four traditions read it?
Each reading below comes from a named tradition and a cited source, so you can see where it came from and decide what fits your dream. The four often disagree, and that is the point: a symbol rarely means one fixed thing, and the distance between Freud, Jung, modern research and myth tells you more than any single verdict could.
Freud
Freud read an enormous range of dream objects as standing in for this one, and that reading is not testable, was contested in his lifetime, and reflects his period's assumptions about women more than his own observation.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
A Jungian reading would be more interested in what the dream did with the body than in the anatomy, and would treat a dream about a body part as being about the dreamer's relation to their own body first.
Our summary of a Jungian reading, in our own words, not Jung's. See Jung, ed., Man and His Symbols (1964).Modern
Bodily dreams frequently have bodily causes, and genital arousal occurs in REM sleep as a matter of physiology in people of all sexes and all ages, entirely independently of dream content. That fact alone accounts for a good deal of what people arrive at this page worried about.

Protective and fertility images of the female body survive in quantity from societies that were entirely unembarrassed by them, and the modern reticence is local and recent rather than universal.
Rosmerta Publishing editorial synthesis (after Frazer).How can writers use this symbol?
The same symbol, read as craft material rather than as a dream. What it does on the page, how genres use it differently, and what happens when you turn it inside out. Written for novelists, screenwriters and poets who need the symbol to actually work, and it ends with something to try.
In literature
The subject is where a great deal of otherwise careful prose becomes either coy or clinical, and the vocabulary problem is real, since English offers almost nothing between the medical and the crude.
Rosmerta Publishing editorial synthesis. Our own words; no quoted text.What it does in a story
It is a place where a writer's assumptions about whose body is default become visible immediately.
Genre conventions
Medical writing is plain. Literary fiction is improving and was for a long time extraordinarily evasive.
How to subvert it
Write it in a register that is neither medical nor charged, in a scene about something else.
Try this
Write two hundred words of a routine appointment described by the patient.
Only the first of these names a source. What a symbol does in a story, how genres treat it, how to invert it and what to try are our editorial judgement as writers and editors, not findings from a body of research. They are offered as craft opinion and should be argued with.
