Dreaming about losing control of a car, especially in a scenario where your husband is drinking, can symbolize feelings of anxiety or concern about your relationship or the dynamics within it. Cars in dreams often represent your journey in life, and losing control may indicate that you feel overwhelmed or uncertain about the direction you're heading.

The fact that you were in the passenger seat while he was drinking could suggest feelings of powerlessness or fear regarding someone else's choices affecting your life. The airborne aspect of the dream might indicate a sense of taking risks or feeling like things are out of control.

Consider reflecting on your waking life—are there any situations where you feel you're not in control or where you're worried about the decisions of those close to you? This dream could be a prompt to address these concerns and communicate openly with your husband about any worries you may have.

Overall, it might be beneficial to focus on regaining a sense of control and clarity in your life and relationships.
