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.
Nothing "happens" when you dream about crabs. If you mean "crabs" as shellfish, the dream could mean that someone is preparing seafood somewhere nearby while you are sleeping, and the odor is influencing your dream.
