Depth Psychology: You have made a final decision in a certain matter— given it your stamp of approval. See Seal. Does the stamp have your Name on it?
(See Seal; Cauterize)
To dream of seeing or buying or using stamps represents a need for communication.
Dreams of a stamp signify your opinions and judgments. Consider the scene in your dream and whether or not you are approving or rejecting, giving your thumbs up or thumbs down.
