To dream of a magpie represents dishonest opportunism. You or someone else is carefully observing a situation and waiting for a moment of weakness to make a move.
A magpie is a sign of dissatisfaction and disagreements. You may feel insecure about what you say or do. You may also feel shortchanged in a relationship. Alternatively, a magpie may represent your own attempt to steal or embarrasses someone as soon as the opportunity arises.
