What does it mean to dream about indigo?
Indigo often suggests depth, intuition, and the inward or spiritual, a deep blue tied to night and quiet reflection.
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 treat a deep colour like indigo as part of the dream's feeling-tone, asking what it covered and what mood it brought. Its darkness might veil as much as it shows. The hue borrows its meaning from what it shades.
After Freud, The Interpretation of Dreams (Brill trans., 1913), public domain.Jung
Jung tied deep blue to thought, spirit, and the depths of the inner life, and indigo is blue at its most inward, near the dark of night. It can read as intuition, contemplation, and a reaching toward the unseen, or as a withdrawn and brooding mood. Whether it steadied or weighed on you is part of the meaning.
Jungian concept (our summary).Modern
Under the continuity view, indigo often follows from a reflective, inward, or low waking mood, or thoughts of evening and the night sky. It may also carry over a deep-blue thing from your day. What the colour suggests to you points the way.
Continuity hypothesis (our summary).Mythological
Indigo dye was prized and traded across the old world, a deep and lasting blue that clothed both the sacred and the costly. As the colour of the night sky it gathered associations with the heavens, the far, and the contemplative. It has long sat close to depth and the eternal.
