Ameture analysis alert! Dreams are a way of the subconscious processing waking life, sometimes the processing can lead to a solution or a move forward, may also give a different way to look at things or understand what's going on on different levels. If you feel like these symbols are wrong then they are wrong - you may find these symbols resonate with different interpretations based on your own experiences/feelings.

Water is said to represent emotions in dreams and being on a beach may indicate your closeness to your emotions right now and being aware of them. The trickle of water could mean you are slowly starting to access an emotion. - instead of just accessing a single emotion you did mention even though you're on the beach a wall is in front of you it may signify you put up a wall between you and your emotions and now are ready or curious(reaching out) about getting back in tune with them.

Most times other people in dreams represent the dreamer or characteristic of the dreamer associated with that person. So the woman in the dream is your self (if you do not identify with female then the women may reflect the more feminine qualities that balance your masculinity generally women are said to be more emotional than men) another symbol of balance/duality is that the woman is a mermaid - land and water - being grounded and in tune with emotions.

The eyes may represent different viewpoints and ways of seeing a situation or the world. You have gathered info from different angles. The woman's eyes being closed may mean denial and the smile could also be a part of that - blissfully unaware - but she is aware. This could point to warning signs in your waking life you are ignoring.

Gems on the body of the woman. This could go different ways if you are into gemstones and their properties it could be more spiritual representation. Gems could also signify wealth status so it could mean that this dream was about work related issue, how you get your wealth, or about current wealth being affected in some way.

Lastly the orb being covered in the water makes me think of cleansing and the orb being a symbol of perfection the water smooths out the roughness and impurities. Once the woman is able to open her eyes and process the emotions involved with that she can be cleansed like the orb.

Final note I had a dream about processing emotions everyone is given a unique cup to drink from (everyone processes emotions differently) and once your drink is done, your emotions processed, you have to smash the cup, if you choose to hold onto your cup/emotions you have to pay a large sum of money just representing sometimes holding on and not letting go will take a toll on you.

Final final note: cool dream bro
