Aerosol in a dream: what does it mean?
A can that turns liquid into a cloud is a small industrial magic, and dreams tend to notice the hiss and the loss of control over where it goes.
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.
How did Freud read this symbol?
Freud would attend to the dispersal, since a dream about something released that cannot be recalled has arranged an irreversible small act.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.How did Jung read this symbol?
For Jung the spray can image something the dreamer has put into the air rather than said, which spreads and settles on everything. What was sprayed matters less than that it cannot be gathered.
Our summary of a Jungian reading, in our own words, not Jung's. See Jung, ed., Man and His Symbols (1964).What does modern dream research say?
Under the continuity view aerosols come from real household objects and from work. The neurocognitive account would read the vivid sensory detail people report, the hiss and cold, as ordinary sense memory.
Our summary of the continuity hypothesis, named by Calvin Hall and Vernon Nordby, The Individual and His Dreams (1972). Its correct scope is disputed; see Domhoff (2017) and the replies to him.What do myth and folklore say?
There is no folklore for the aerosol, and the absence is worth stating: it is a mid-twentieth-century object. What traditions do have is a great deal about smoke and incense, which is the older way to put something in the air.
Rosmerta Publishing editorial synthesis (after Brewer).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.
Where does this appear in literature?
Graffiti writing has produced the best literature of the spray can, because it treats it as a tool with a technique rather than as vandalism with a prop.
Rosmerta Publishing editorial synthesis. Our own words; no quoted text.What does it do in a story?
It lets a character alter a surface quickly and irreversibly, which is useful. Structurally it is an act of marking: territory, protest, or damage, and the reader reads the intent from context.
What are the genre conventions?
Urban fiction uses the tag. Crime uses the covered plate. Domestic fiction uses the cleaning products under the sink, which is the version everyone actually owns.
How to subvert it
Write somebody using an aerosol entirely correctly and legally, and make the scene tense anyway.
Try this
Write two hundred words of someone painting over graffiti, from the painter's point of view.
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.
