This dream may reflect feelings of insecurity and mistrust in your relationship. The presence of your boyfriend and his actions in the dream suggest that these feelings may be related to your current relationship. The act of sexting and sending a dick pic can symbolize a desire for sexual attention and validation from others. This could indicate a fear of your partner being unfaithful or not fully committed to you. Alternatively, it could also represent your own insecurities and doubts about your own desirability and worthiness of love. The dream may be urging you to address these issues and communicate openly with your partner about your concerns. It could also be a reminder to trust in yourself and your relationship, and not let outside influences or insecurities affect your happiness. Consider reflecting on any underlying trust issues or insecurities in your relationship and finding ways to address them together.
