Dreams involving intimate relationships and scenarios like threesomes can often reflect your feelings about trust, jealousy, and boundaries. In your dream, allowing your boyfriend to engage with your friends may symbolize a sense of openness or exploration regarding your relationship. However, the moment you felt discomfort or freaked out after they had sex suggests underlying insecurities or fears about losing intimacy or connection with your partner.

This dream might be highlighting your feelings about trust in your relationship and your comfort levels with sharing your partner. It could be beneficial to reflect on your current feelings toward your relationship dynamics, boundaries, and any insecurities you may have. Consider discussing your feelings with your boyfriend to ensure both of you are on the same page regarding your relationship and any potential explorations.

Ultimately, this dream serves as a prompt for self-reflection regarding your comfort with intimacy, boundaries, and trust in your relationships.
