Dissolving in dreams can have different meanings: completely lose something, the idea of arrival, no specific time frame, or the disappearance and rebirth due to inner struggles with real life.
The idea of maintaining balance implies that dissolution might occur when one desires everything to simply disappear.
Dissolving images can symbolize positive moments coming and going in our lives that remind us that we need to appreciate each moment for what it is rather than focusing too much on its trajectory towards more endpoints.
Also, after a breakup or ending of some sort of relationship, people may dream about dissolving everything from their minds to get over it. Perhaps someone has made them angry and just destroying things experimentally might contribute to feeling better about oneself; maybe that person feels so guilty about some of their past deeds that acknowledging flaws would make them feel physically sick. In such instances, people logically fear change and feel that simply erasing those things would be more desirable for them than addressing them again head-on.
