What does it mean to dream about iris?
An iris often pictures a message or a bridge between worlds, a tall striking flower long tied to the rainbow and to news carried from afar.
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 would ask what the iris meant to you, perhaps a garden, a colour, or a name. As a bold, elegant bloom it can dress a wish for beauty or for word from someone the waking mind keeps quiet. Its many colours might also reflect mixed feelings about a message awaited.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung might read the iris as an image of communication within the self, a link between the conscious and what lies beyond it. Its tie to the rainbow can suggest a bridge between inner worlds. To meet one may mirror a message the psyche is trying to deliver.
Jungian concept (our summary).Modern
Under continuity, an iris tends to follow waking thoughts about news, beauty, or someone at a distance. A vivid bloom may track hope, while a closed bud can mirror waiting. Notice whether you have been expecting word from anyone.
Continuity hypothesis (our summary).Mythological
In Greek tradition Iris was the messenger goddess of the rainbow, carrying word between heaven and earth. The flower took her name and her sense of the rainbow's bridge. So the iris has long stood for messages and the link between worlds.
