Blue in Dreams: Meaning in Depth Psychology

The color of depth and distance. Blue reaches up (sky, spirit, truth) and down (deep water, feeling, melancholy) at once. A blue dream often carries longing: for something higher, something deeper, or something just out of reach.

THE CORE MEANING

Spirit, depth, truth, melancholy, the sky (transcendence) and the deep ocean (the unconscious). The color of both distance and depth: what's above and what's below.

VARIATIONS: CONTEXT CHANGES THE MEANING

sky blue: Spiritual openness, mental clarity, the thinking function at its clearest, transcendence
deep blue: The deep unconscious, emotional depth, the ocean floor of the psyche
blue mood: Melancholy as a psychological state: the soul's sadness that serves depth. Depression as descent.
blue figure: A spiritual or transcendent figure, the Wise Old Man/Woman in their cosmic aspect
