Question: What is the spiritual difference between dreaming in colour and dreaming in black and white?

Sri Chinmoy: Dreaming in colour signifies different phases in one’s life, different types of consciousness in one’s life, either progressive or destructive. Dreaming in black and white signifies the union of darkness and light, night and day, negative, destructive forces and positive, constructive forces.
