Dreams about public places, especially involving authority figures like police officers, can often reflect feelings of vulnerability, judgment, or concern about how others perceive you or your loved ones. In your dream, your girlfriend being arrested for a seemingly innocuous action like winking might suggest feelings of worry about how her actions could be misinterpreted or lead to unintended consequences.

This dream could also indicate your own feelings of protectiveness over her or concerns about her behavior in social situations. It might be worthwhile to think about any recent events or emotions in your relationship that could be influencing this dream. Are there any underlying fears or anxieties you have about your relationship or her interactions with others?

Consider discussing any feelings of vulnerability or concerns you might have with her, as open communication can strengthen your bond and alleviate any worries.
