Empty vase
A vase with no flowers in it — a holder waiting for what it was designed to receive.
An empty vase in a dream is the dream's image of a holder waiting for what it was designed to receive. The vase is fine; the flowers it was made to display are not in it. The dream brings the empty vase when something in your life — a household role, a public function, a ready space for hospitality — is in place and is currently not being given the content it was made for. An empty vase noticed and filled is the dream affirming the return of the use. An empty vase kept on display, with the absence becoming the decoration, is the dream noting that the holder has become the message, and the missing content is no longer being expected.
