My brother told my mom I have a boyfriend. (But I don't, I'm a lesbian)
Dreams about your family members revealing something personal or unexpected about you may indicate feelings of vulnerability or fear of judgment in waking life. In this case, the fact that your brother shared a false information about your relationship status may point to concerns about acceptance and openness regarding your sexual orientation. The dream could be reflecting a fear of coming out or being misunderstood by your family and feeling unprepared for discussions about your personal life. It may be a symbol of the internal struggle you may be going through while navigating your identity and relationships with your family members. It could be a prompt for you to address any unresolved feelings or concerns you have about revealing your true self to those close to you.
