A block suggests either a preventative measure or a warning to ensure that we do not make a mistake. Blocks appear in dreams when we need to make a special effort to overcome an obstacle to progress. In dreams, a block may present itself in many forms. We can experience it as a physical block - that is, something that needs to be climbed over or got round, a mental block - for instance, not being able to speak or hear, or a spiritual block such as the figure of an angel or a demon appearing in our dreams. A block as in a cube represents the physical material realm in both mens and womens dreams. You might also like to consult the entry for Obstacle/Obstruct/Obstruction.
