Dreams about playing basketball often symbolize teamwork, competition, and personal goals. The sudden stiffness in your arms may represent feelings of powerlessness or a fear of losing control in a situation in your waking life. It might suggest that you are facing obstacles that are preventing you from achieving your goals or expressing yourself fully.

Consider reflecting on areas in your life where you feel restricted or unable to act. Are there situations where you feel overwhelmed or unable to contribute? This dream could be prompting you to think about how to regain control or seek assistance in overcoming these challenges.
