Dreams featuring deceased loved ones, especially parents, can be quite powerful and emotional. When your father appears in a dream and expresses disapproval of your partner, it may reflect your own feelings or uncertainties about the relationship.

Here are a few interpretations to consider:

1. Inner Conflict: Your father’s visit may symbolize your subconscious mind grappling with feelings of doubt or concern about your partner. This could indicate that you have some reservations that you may not have fully acknowledged.
2. Guidance and Protection: Many believe that deceased loved ones visit us in dreams to offer guidance. Your father’s message could be a reminder to trust your instincts and consider whether your partner is truly right for you.
3. Emotional Processing: Dreams can serve as a way to process grief and unresolved issues. Your father's presence might be an expression of your desire for his approval in your life decisions, particularly in relationships.
4. Symbolic Representation: Your father could symbolize authority or traditional values, and his disapproval might reflect societal or familial expectations that you feel pressured by.

Ultimately, the meaning of your dream is deeply personal. Reflect on your feelings toward your relationship and any underlying concerns you may have. It may also be helpful to communicate openly with your partner about your feelings.
