Rainbow vs Twin or Double

Rainbow

Rainbows appear after storms and universally symbolize hope, promise, and beauty emerging from difficulty. A rainbow in a dream may indicate that a difficult period is ending and beauty is ahead. In Biblical tradition, the rainbow represents God's promise. In many cultures, the rainbow is a bridge between earth and heaven. The full spectrum of colors represents wholeness and the integration of all aspects of self.

Twin or Double

Seeing your double, twin, or doppelganger in a dream represents confrontation with another aspect of yourself — perhaps a side you don't normally acknowledge. This can represent inner conflict between two desires, the gap between who you are and who you present to the world, or the emergence of an undeveloped part of your personality seeking integration.
