This dream may reflect inner conflicts you are experiencing between your personal desires and your responsibilities. The group represents aspects of your life that require teamwork, collaboration, or community, while your lover symbolizes your emotional needs or desires for intimacy.
Leaving the group to be with your lover could suggest that you feel pulled towards personal relationships at the expense of your commitments. Coming back late might indicate feelings of guilt or anxiety about neglecting your responsibilities or fear of disappointing others.
Consider reflecting on your current life situation. Are there areas where you feel torn between professional obligations and personal desires? This dream may be urging you to find a balance between your responsibilities and your need for connection. It could also be a prompt to communicate openly with those in your life about your needs and boundaries.
