This dream may reflect feelings of anxiety and vulnerability regarding health and medical situations. The bruises you mentioned could symbolize emotional or physical wounds you are currently dealing with. The doctor's office often represents a place of healing, but your anxiety about the injection suggests that you might be struggling with a fear of facing certain truths or challenges in your life.

Running away from the nurse could indicate a desire to avoid confronting something that needs your attention, whether it's a personal issue or a decision you need to make. The forceful injection could symbolize a situation where you feel you have no control, but the realization that it wasn't so bad afterward could suggest that facing your fears may lead to relief or healing.

Consider what aspects of your life may be causing you stress or anxiety, and think about how you might address them. Apologizing in the dream may point to a need for reconciliation, either with yourself or with others regarding these feelings. Overall, this dream encourages you to confront your fears rather than evade them, as the outcome may be less daunting than you expect.
