To dream of an aquarium ornament represents something uncertain about yourself that you feel is important to be noticed all the time. A possibility that you want others seeing in you. It may also reflect a negative aspect of yourself that you like others being aware of in you.
Negatively, you may feel that people need to believe something about you at all times or that you can’t move forward in a situation if something isn’t being noticed in you by others.
Example: A man dreamed of looking into an aquarium and seeing an ornament turn scary looking. In waking life he was beginning to fear that a promise his father made to him about giving him a big some of money wasn’t going to happen. He had told a lot of people about the gift of money happening and felt his eccentric father might embarrass him in front of the people he discussed the money with.
