To dream of eating oysters symbolizes the placing of sensual pleasures above wisdom.

In your attraction to someone, or your desire for material goods, you may lose your senses and morality in your attempt to indulge your desires.

If you saw oysters but did not eat them, you are confident without being conceited, but you may tend to be a bit distant from others.

A dream of oyster shells foretells that you will be frustrated when your attempt to get something that belongs to someone else, does not work out.
