What does it mean to dream about weasel?
A weasel often points to cunning, quickness, or a wariness about someone slippery, in your dealings with others or within yourself.
Four ways to 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.
Freud
Freud might read the weasel's darting, narrow body as a figure for a desire that slips past the censor and refuses to be pinned down. Its reputation for sly raids could picture an impulse the dreamer half disowns. He would ask what slipperiness brings to mind for you.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
For Jung the weasel can image the trickster instinct, quick and resourceful but not always to be trusted. Meeting it in a dream may invite you to notice where you are being cunning, or where you sense cunning aimed at you.
Jungian concept (our summary).Modern
In continuity terms a weasel may echo a recent sense that someone has been evasive or that a deal felt slippery. Many dreamers find the unease points back to a waking situation where trust felt thin.
Continuity hypothesis (our summary).Mythological
Classical and European folklore often cast the weasel and stoat as sly, swift, and sometimes uncanny, and phrase and fable preserve the word as a byword for evasive talk. Some old tales also granted the creature healing or protective power against snakes.
