In oneiric terms, the shore is the point where the unconscious (sea) and conscious (beach) meet. The dream could also be representing the possibility of a journey. This could be physical (by boat), or symbolic (within yourself).
If you find yourself scanning the horizon looking for a boat, you may be worried about not reaching some aspiration or desire. To be on the shore looking for shells or other objects hidden in the sand could reflect your desire to increase your inner resources. (See Also: WATER, SEA)
An empty beach symbolizes an opportunity. A beach with a lot of people predicts that you will feel protected and safe.
