There´s this girl called Nani, we had a relationship that she decided to end 8 months ago, and I still haven´t fully recover from that. In my dream I was with her brother and some other guy, in a beach vacation place... it looked like a hotel, but we were writing something. Then, Nani appeared with some other girl (I don't remember a face or a name). I immediately got mad and sad at the same time. She came to tell me something and I immediately rejected her, in a hard way... and she responded laughing: "you´re still mad at me?".
Based on the content of the dream, it seems that you are still struggling to let go of the past relationship with Nani. Your emotions in the dream suggest that you are still hurt and angry about the situation. The beach vacation setting may suggest a desire for relaxation or escape, but the presence of Nani and her brother indicate that you are unable to fully escape memories of the past. The fact that Nani appears with another girl suggests that she has moved on, while you are still emotionally entangled with the past. Overall, the dream may indicate a need for closure and acceptance of the situation in order to move forward.
