Dreams involving animals, particularly wolves, often symbolize instincts, intuition, or a sense of danger. In your dream, the wolf sniffing around the river may represent an underlying concern or threat that you feel is lurking in your life, possibly related to your family dynamics given that your sister and dad are present.

The act of your sister driving and the car being attacked could signify a feeling of vulnerability or being overwhelmed by situations you cannot control. The circular driving may indicate a sense of confusion or being stuck in a cycle, perhaps representing a situation where you feel you're not making progress.

Your father's reaction, spraying a scent remover instead of answering your question, could suggest a desire to avoid addressing certain issues directly. It may reflect feelings of frustration or a need for clarity in your relationship with your family or in a specific situation.

Overall, this dream could be encouraging you to confront any fears or uncertainties in your life rather than avoiding them. It might be beneficial to communicate openly with your family about any issues that are weighing on your mind. Consider what the wolf represents for you personally and how it relates to your current circumstances.
