Dreams often reflect our subconscious thoughts, feelings, and experiences, and your dream seems rich with symbolism and emotional undertones. Let's break it down:

1. Haunted House and Group Dynamics: The haunted house could symbolize fears or unresolved issues in your life. The changing sky might represent the passage of time or different phases in your emotions. The group of people struggling to get organized could signify feelings of pressure or anxiety about not being prepared for something significant in life.
2. Ex-Boyfriend and Emotional Conflict: Your ex appearing in the dream indicates that you may still be processing past feelings or unresolved emotions regarding that relationship. His clinginess and your discomfort may reflect a struggle between past attachments and current commitments. It’s common to revisit past relationships in dreams, especially if there are unresolved feelings.
3. Your Current Boyfriend: The presence of your current boyfriend, and the comfort you felt in hugging and kissing him, suggests that you value your current relationship greatly. The relief you sensed in him indicates a deep emotional bond and a desire for security and commitment.
4. Decision-Making and Guilt: The struggle to find words to explain your feelings to your ex and the guilt of leaving your boyfriend behind might symbolize an internal conflict about choices in your life. You may be feeling pressure to balance past relationships and current commitments, which could reflect uncertainties in your waking life.
5. Nervous System Regulation: The sensation of your body feeling regulated with your current boyfriend signifies a sense of safety and emotional grounding when you're with him, contrasting sharply with the anxiety you felt when near your ex.

Overall, this dream suggests a journey of self-exploration regarding your relationships, highlighting themes of commitment, emotional safety, and unresolved past connections. It may be helpful to reflect on your feelings about both relationships and any lingering concerns about your past that might need closure. Engaging in open communication with your current partner about your feelings could also foster deeper trust and connection.

Thank you for sharing your dream. It seems to encapsulate a variety of themes, including fear, relationships, and the struggle for clarity in your feelings.

The haunted house could symbolize confronting fears or unresolved issues in your life. The interruptions may represent distractions or obstacles that prevent you from addressing these fears directly. The changing sky signifies the passage of time and possibly your shifting emotions regarding the situation you're facing.

Transitioning to the second part of your dream, where you are with your mother and your ex-boyfriend, suggests a revisitation of past relationships and feelings. Your discomfort around your ex may highlight unresolved feelings or conflicts from that relationship, contrasting with the positive feelings you have for your current boyfriend. The act of hugging your current boyfriend and feeling a sense of relief indicates a deep emotional connection and the importance of that relationship for your well-being.

The struggle to communicate your feelings to your ex while feeling the pressure of his emotions indicates a desire to assert your current relationship while navigating past attachments. This could reflect a need for clarity in your life regarding your commitments and the importance of setting boundaries.

Overall, this dream may be urging you to confront your fears, acknowledge your past, and communicate your feelings more clearly in your waking life.
