Recently I had a dream when crabs were covering my yard eating a three foot long crab, and then someone told me I was made out of crabs. Do crabs have any meaning at all in dreams? Or was that just a really weird dream?
Crabs are representative of tenacity and perseverance, often to a fault. They are also representative of irritability - being 'crabby.' Crabs are creatures of water, and water is associated with emotion and intuition.
To me, this dream suggests that you are holding on to negative emotions. I believe the large crab was you, and the smaller crabs represent how this negativity slowly 'devours' you. Your subconscious is warning you to let go.
