Dreams about past relationships, especially involving an ex or situationship, can often reflect unresolved feelings or thoughts about that person and the connection you had. In your dream, going to a carnival symbolizes fun, excitement, and perhaps a desire for a carefree experience, but it also may indicate a sense of unpredictability in your current relationship with this person.

The broken arm of your ex could symbolize a feeling of limitation or inability to fully engage in a relationship, mirroring his decision not to pursue one currently. This might suggest feelings of frustration or a sense of loss regarding the relationship.

The appearance of the actor from your favorite show might represent an ideal or an aspiration. It could signify a longing for something more meaningful or a desire to escape into a fantasy that contrasts with your current situation.

Overall, this dream might be prompting you to reflect on your feelings about this person and the relationship you share, as well as your desires for connection and fulfillment. It could be beneficial to explore what you truly want and whether this situation aligns with that. Consider what aspects of your past relationship you miss or wish to revisit, and how they relate to your current emotional state.
