Dreams about selling items and interacting with strangers can often reflect feelings of vulnerability, trust, and anxiety about exposure or judgment. In your dream, the act of selling something on a marketplace may symbolize a desire for connection or validation in your waking life, but the request from a stranger for a photo of your face suggests feelings of unease and a potential invasion of privacy.
Feeling unsafe in the dream indicates that you may be grappling with fears about revealing too much of yourself to others or concerns about how you are perceived. The image of your face showing up everywhere might represent worries about losing control over your personal identity or being judged by others.
This dream could be prompting you to consider how you protect your personal boundaries and manage interactions with unfamiliar people. It's important to trust your instincts in real life and prioritize your safety. Reflect on any recent situations where you felt vulnerable or exposed, and think about ways to reinforce your sense of security and privacy in your daily life.
