Dreams of being injured or in a weakened state often reflect feelings of vulnerability or helplessness in waking life. Your struggle to move and the severe injury to your arm may symbolize a sense of loss of control or difficulty in navigating a situation that is important to you, much like the journey to the hospital suggests a need for healing or support.

The fact that you were in a school setting could suggest that these feelings are connected to a learning environment or experiences from your past. Schools often represent growth, education, and social dynamics, which may indicate that you feel overlooked or unsupported in your efforts to grow or address issues in your life.

The lack of attention from others in your dream might point to feelings of isolation or a belief that your struggles are not being recognized by those around you. This could reflect real-life situations where you feel unacknowledged or unheard.

To gain insight from this dream, consider reflecting on areas in your life where you feel vulnerable or unsupported. It may be helpful to seek out supportive relationships or reach out for help in circumstances where you feel you need it. Acknowledging your feelings and finding ways to express them can also contribute to your healing and empowerment.
