Dreaming of your mother in an operation room can evoke strong emotions and may symbolize various things depending on your personal circumstances and feelings. Here are a few interpretations:

1. Concern for Health: If your mother has been unwell or undergoing medical issues, this dream might reflect your worries about her health and well-being.
2. Transformation: An operation is often associated with significant change or transformation. This dream could symbolize your feelings about changes happening in your family dynamics or in your relationship with your mother.
3. Need for Support: You might be feeling vulnerable or in need of support, and seeing your mother in a medical setting could indicate a desire for her guidance or comfort during a challenging time.
4. Control and Healing: The operation room can also symbolize a desire to take control of a situation that feels chaotic or out of your hands. It might represent your wish to 'fix' something in your life or family.

Consider reflecting on your current relationship with your mother and any recent events that might be influencing this dream. It might be helpful to talk to her about your feelings if you feel comfortable doing so.
