To dream of emptiness, suggests that there is something missing or lacking in your life. It symbolizes fruitless labor, an emotional void, or loneliness. There is nothing to show for all the effort that you have dedicated to a project or relationship. In particular, to dream that a container is empty, then it represents optimism.
Afeeling of emptiness in a dream signifies for you in the near future, a humiliating position, or any humiliating duties.
