What does it mean to hold crab in your dream?

If the question is about holding a "crab" - a crustacean (shellfish) with large claws - the dream could reflect the dreamer's feelings about someone who is "crabby" or grouchy and unpleasant. Another possible connection could be with "cancer" as the crab is called in Astrology. In that case, the dreamer is holding cancer in the sense that the dreamer might have received or fears that diagnosis, or is caring for someone with that disease. Alternatively, it could be nothing more than a dream triggered by an appetite for tasty shellfish.
