An abalone is a creature that lives in a shell, so if you dream about an abalone it can mean that you are feeling vulnerable or threatened.
Alternatively, an abalone in a dream can signify a need to break out of your shell. You may feel that you have been unable to express yourself.
Because abalone is a considered delicacy, if you dream about abalone, it can mean that you need extra emotional nourishment, and that you require special attention. This could be the result of your being in a vulnerable state.
