This dream may symbolize feelings of instability and failure in your waking life. The house represents your sense of self and the bridge represents a connection or pathway in your life. The collapse of the bridge suggests a breakdown or disruption in this connection, possibly leading to a sense of chaos or loss. Shooting a duck may represent a desire to take control and solve the problem, but being unable to remove the shell may indicate a struggle or inability to overcome the issue. This dream may reflect a fear of failure or a sense of powerlessness in a situation. It could also suggest a need to find alternative solutions or seek help from others. Consider the emotions and events in your waking life that may be causing these feelings of collapse and failure, and try to address them in a proactive and positive manner.
