Dreams about pastors or figures of authority often reflect your feelings about guidance, spirituality, or moral direction in your life. In this dream, the act of the pastor trying to put on his canvas could symbolize a struggle with preparation or readiness, either in a personal project or in a spiritual context.

Your initial decision to drive off may indicate feelings of responsibility or guilt about leaving someone behind or not being ready to support others. Turning back to pick him up suggests a desire to reconnect with your sense of duty or to help those who may need your support.

Consider the following interpretations:

1. Responsibility and Support: You may feel a sense of obligation to help others, especially those who are in a position of guidance or leadership in your life.
2. Readiness: The pastor's struggle to put on his canvas might reflect your concerns about being prepared for a situation in your life. It could be a reminder to ensure you are ready before moving forward.
3. Spiritual Reflection: Since pastors often symbolize spiritual matters, this dream might indicate a need for deeper reflection on your beliefs and how they align with your actions.

Think about any current situations in your life where you feel responsible for others or where you may be struggling with your own readiness. This dream could serve as a prompt to evaluate those areas.
