Dreams involving authority figures, such as police officers, often reflect feelings of safety, control, or power dynamics in your waking life. In your dream, being pulled over by an imposter police officer could symbolize anxiety about being misled or betrayed by someone you trust. The act of recording the situation may suggest that you feel the need to document or validate your experiences, perhaps because you're worried about your credibility or the truth being overlooked.

The bag over your head represents feelings of helplessness or a loss of control in a situation, which can be quite distressing. The attempted robbery and violence might signify fears of being taken advantage of or harmed by someone in your life, either emotionally or physically. Your fight back indicates a strong desire to reclaim your power and defend yourself against threats.

The arrival of real officers who have seen your recording implies that there is a sense of justice or resolution in your life. It suggests that you may find support from others who recognize your truth and will help you overcome challenges.

Overall, this dream could reflect internal struggles with trust and safety, as well as a desire for validation and protection. It may be helpful to reflect on any current situations in your life that evoke similar feelings and consider how you can assert your boundaries and seek support.
