A buckle can have a double meaning in spiritual terms. It can represent a protective element against the forces of evil; it can also help us to take the strain and not 'buckle' under pressure. To be fastening a buckle in a dream shows that we accept responsibility for what we do. It can also suggest 'locking in' a specific type of energy. Dreaming of an ornate buckle has the same symbolism as that of a belt, in that it can represent the holding of high office or status. It can also indicate honour and can be a symbol of loyalty or membership of a particular group of people. You might like to consult the entries for Belt and Girdle.
