The meaning of the colour blue in dreams point to thoughts, ideas, dreams and the ability to convey them.
In general it’s a representation of the dreamer’s moods. Perhaps you are expressing a desire to get away, or your optimism towards the future.
Depending on the shade, blue can mean different things in dreams. Dark blues may be foreboding, or an indication of worry, fear or even a feeling of nostalgia or lack of romance. Lighter blues may symbolize hope, healing and a high level of spiritual awareness.
It also can represent truth, wisdom, heaven, eternity, devotion, tranquility, loyalty and openness.
