Your dream is rich with symbolism and emotions that can provide insight into your current feelings and situations in your waking life. Here are some possible interpretations:

1. Chase and Fear: The dogs chasing you can symbolize fears or anxieties that you are currently facing. They might represent feelings of being overwhelmed or threatened by circumstances in your life. The park setting, often associated with freedom and nature, could indicate that you are feeling trapped or confined despite your desire for peace.
2. Relationships: Your boyfriend C plays a significant role in your dream. The contrast between your normal life together and the chaotic, punk house suggests a feeling of instability in your relationship or a fear of losing the connection you share. It may reflect concerns about how you perceive your relationship in different contexts—normal versus chaotic.
3. Lucid Dreaming and Control: The realization that you're dreaming and your attempts to gain control through jumping indicate a desire for agency in your life. You might be feeling like certain aspects of your life are out of control, and you wish to take charge of your circumstances.
4. Dimensions and Reality: Your insistence that you are from another dimension where you and C are a couple reveals a desire for a deeper, more committed relationship. It reflects a longing for a reality where you feel more secure and understood.
5. Response to Rejection: The laughter and disbelief from the roommates can symbolize feelings of not being taken seriously or feeling misunderstood in your waking life. This might relate to your fears about how others perceive your relationship or your emotional state.
6. Repetition of Themes: The transition from day to night and the shifts in settings may represent the ups and downs you experience in your life, highlighting a sense of instability or uncertainty.

Overall, your dream suggests that you are navigating complex emotions regarding relationships, fears, and a desire for control. It may be helpful to reflect on your current relationships and emotional state to see if there are areas where you seek more stability or understanding. Consider discussing your feelings with C to strengthen your connection and address any underlying anxieties.
