Pubic hair in a dream: what does it mean?
This appears in dreams the way other body detail does, and reports usually attach to a change in it rather than to its presence.
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 tied body hair to his developmental account and to shame in ways that reflect the period, and the durable part of it is his general observation that shame is taught rather than innate.

A Jungian reading would attend to a body changing rather than to the detail, and would take a dream about the body at a particular age as being about that age.

Bodily dreams frequently follow bodily events, and adolescence, illness, treatment and ageing all produce them. Dreams about body hair specifically often track a recent real change, and the neurocognitive account would look for the ordinary explanation before any other.

Removal practices and their meanings vary enormously across traditions and periods, and the confident modern claims about what is natural or normal have very little historical support.
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 body in fiction is described selectively and the selection reveals the writer's assumptions faster than any statement of them would. The wider point is that bodies in fiction are nearly always described in the register of desire or of disgust, and the enormous middle ground, a body simply being lived in, is very thinly written.
Rosmerta Publishing editorial synthesis. Our own words; no quoted text.What it does in a story
It marks the point at which a body stopped being a child's, which is why it appears in so much writing about adolescence.
Genre conventions
Literary fiction goes plain. Commercial fiction goes silent, which is its own decision.
How to subvert it
Write it in a medical register, without embarrassment, in a scene about something else.
Try this
Write two hundred words of a body noticed by its owner in a mirror.
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.
