To see a crab in your dream signifies you perseverance and tenacity. On an extreme note, you maybe be too clingy and dependent and hanging on to a hopeless endeavor. Crabs are also symbolic of your irritable personality, as in the pun, being “crabby”
Dreaming of a crab indicates that you are being stingy or needy and holding on to someone or something too tightly. It suggests that you are being irritable or emotionally insensitive as well. Or it may represent someone in your waking life who is acting in these ways. The dream crab may be a symbol of self-protection.
In some cultures, the crab is a symbol of poor health or an indication that you are not facing your problems effectively. Because the crab in Nature moves backwards and sideways, its appearance in a dream may symbolize your inability to look at difficulties “head on” to overcome them.
The appearance of a crab in a dream is telling you something about how tenacious and persevering you are: are you being “clingy” and dependent on someone? Or perhaps there is someone around you who is overly dependent on you.
Seeing a crab in a dream almost always represents something about your character. It is telling you that you are determined and constant in your emotions, but you may also be overly “crabby” and annoying.
The shell of the dream crab is an important part of its symbolism. It suggests that you are protecting yourself, hiding your weaknesses, and fear finding too much risk in a situation. The dream crab may be telling you that you are overly concerned with security and safety. In terms of romance, the crab is associated with long and difficult love affairs and warns about avoiding rivals to a relationship.
While the dream crab may appear to be a negative symbol, it also has positive connotations. For example, in some metaphysical areas, it represents the sea and sky, the physical nourishment obtained from the oceans, and intellectual nourishment as well. Because the crab lives in water, it also represents those areas of life associated with emotions and the Unconscious.
