A Mermaid in your coffee cup can be a sign that you will have an increased awareness of the influences of your subconscious. Perhaps you will have greater access to your imagination and perhaps you feel a strong connection to your emotions right now. Being close to the water and the ocean can also be very beneficial. Mermaid can be a sign that you will be in an environment where you are very suitable unless, of course, you see a mermaid who tries to get on dry land. In that case, the message is to be more adaptable to your situation and your surroundings.
