Your dream appears to reflect a mix of emotions and experiences related to performance, responsibility, and recognition.

The scenario of preparing for a violin concert, despite not being a violinist, suggests feelings of anxiety or pressure related to performance and expectations. The act of your sister handing you the violin and the oil may symbolize support from those close to you, but the oil spilling could represent fears of making mistakes or causing problems. However, the kindness of your teacher in the dream indicates a nurturing presence in your life, suggesting that you may have support in facing your fears or challenges.

The surprise at not seeing your piano teacher initially and then realizing he was there could signify a sense of discovery or realization about your own capabilities and the roles people play in your life. It may also indicate a feeling of pride in recognizing the support and guidance you receive from those around you.

Helping the ladies in your dream suggests a desire to be helpful and to take on a nurturing role. It reflects your instinct to support others, especially when they are in need. The gratitude and compliments you received may symbolize your own need for validation and appreciation for your efforts in real life.

Overall, this dream seems to highlight themes of performance, support, responsibility, and the value of helping others. It might be beneficial to reflect on how these themes resonate with your current life situation and your feelings about your abilities and relationships. Consider acknowledging your achievements and the positive impact you have on those around you.
