Dream: I have seen myself undressing in front of the mirror and I see myself naked.
DreamsMaster: To undress in front of a mirror and to see yourself naked likely means that you are becoming fully open and honest with yourself. Did you experience any specific emotion in your dream? For example, when you saw yourself naked, did you have a negative reaction to what you saw, or did you feel acceptance? If you had a negative reaction, then the dream may be urging you to come out from behind your public façade, and become less judgmental and more accepting of your true self.
We may fool ourselves with trumped-up and distorted self-portraits in waking life but sleep is no friend to embellishment and illusion. Dreams are the mirror of the self.
