On the other hand it may also imply happiness, euphoria, and that you are as happy as a clam. Alternatively, it could be that something in your life feels sticky or uncomfortably close, as in clammy. Should a clam or clams appear in your dream are you closing up, withdrawing, withholding, avoiding, being reticent or clamming up in some way in waking life? Perhaps you are keeping a secret.
Another interpretation is that you are worried about your state of dependence, having attached yourself to someone or something because you believe that you cannot make it on your own. Oysters are also traditionally thought to be aphrodisiacs, so is it time to reinvigorate your love life? If the oyster shell was empty, could your unconscious have been indicating events that have passed you by, or do you think the world is no longer your oyster? If a mussel features in your dream, this may suggest that you are afraid to reveal your soft, pulpy and vulnerable interior and are in a state of hiding.
If you came across an oyster in your dream, was the shell open or closed? If the oyster shell was shut, it may be hinting that your unconscious contains a pearl of wisdom. Dream shellfish-in the same manner as the crustaceans-represent the defensive shell you may use in waking life to avoid hurt or emotional involvement. If a shelled mollusk, such as a scallop or cowry, caught your eye in your dream, this may suggest female sexuality.
