A place of transition between spiritual and material: emotions and mental tranquility.
To see yourself working on a beach shows that you will soon be involved with a job, or project, that will be demanding of you in both time and effort. If you are just relaxing on a beach this shows that you value the calm feelings that family get togethers lend to you, and if you see yourself sitting on a beach and letting the sand run through your fingers that shows that you are running out of time on something important due to idling your time away.
The beach in your dream symbolizes the meeting between your two states of mind. The sand represents your rational brain, while the water symbolizes your irrational and emotional aspects. To dream that you are on the beach and looking out toward the ocean indicates unknown and major changes that are occurring in your life. To dream that you are looking toward the beach suggests that you are returning to what is familiar to you. To dream of relaxing on a beach means that the coming weeks will be calm and peaceful for you. To dream that you are working on the beach represents a project that will take up most of your time.
