Crabs mainly inhabit the sea and therefore have traditionally been associated with aspects of your unconscious. They may symbolize the ability to cultivate homely energy in various circumstances, as crab power is the energy of making a home, however far away from home you may be. Crabs also represent the energy of the psyche that rejects change and finds it hard to let go; the side of us that hangs back instead of taking a chance.
If you are bitten or pinched by a crab in your dream, it is possible that some part of your current situation is resistant to change; this might be because of yourself, or because of another. The armored body of the crab suggests the need to protect yourself against something or someone, and the pincer-like claws show a willingness to attack or tackle whatever obstacles lie in their path.
If a crab appears in your dream, could it be a reflection of a crabby or bad-tempered aspect of your personality; an aspect that resists the attempts of others to penetrate the rough outer shell you have developed in waking life to protect your soft emotional center?
If your dreaming mind saw a crab or lobster without its shell, this is a symbol of your feelings of emotional vulnerability.
If the crab scuttled sideways in your dream, this may mirror a tendency to be evasive when others try to get too close to you or it may also reflect your inability to think logically or in a straight line. Additionally, with their habit of burrowing under the sand, the crab may represent anything that is sapping your energy. Bear in mind, too, that the crab is the symbol for someone born under the astrological sign of Cancer, so your dream crab may be referring to them.
If a shrimp appears in your dream, this may represent rivalry or resentment towards someone, as ’shrimp’ is often a disparaging nickname. But when coupled with the mother image of the sea, the shrimp may represent the reawakening of dormant sibling or childhood rivalries.... The Element Encyclopedia
Because the body often represents the self, loss of body parts or injuries to your body in dreamland can symbolize the emotional pain of losing parts of yourself. A dream that some part of your body is amputated can leave you with a feeling of irreplaceable loss. Such images may refer to the loss of a loved one but they can also appear when what you have lost is less tangible—for example, the love or respect of someone or your own self-respect. Psychologists give the name‘fragmentation’ to the process when you give up parts of yourself in order to fit in with or please others. This is something we all do, but if your own true nature is overly censored, the unconscious may send out warning signals about what you stand to lose by the denial of aspects of yourself.
Dreams in which you lose a hand or a foot,are missing an internal organ or have a body part disappear or fall off are therefore often signs that some part of your potential is being lost due to the path you have chosen. The common dream of losing teeth may reflect waking problems but can also symbolize loss, the break up of relationships, moving house, moving away or any other change which involves the ending of one phase in life and the beginning of another.
If the teeth become loose but stay in your mouth choking you, this could mean that you are holding something back or keeping your thoughts and feelings to yourself; the price is some form of damage to yourself. A dream in which you lose your virginity is a reflection of the loss of childhood innocence. What have you lost recently in waking life that has damaged your previous system of beliefs?
