A stranger
Psychological (Freud)
Psychologically a stranger often embodies a hidden, as-yet-unknown part of the self, a split-off trait, or a repressed desire. How we meet them, with curiosity, fear, or attraction, reveals our stance toward what remains unlived and unrecognised within us.
Oriental reading
In the Oriental and Islamic tradition a stranger is often a herald of unexpected news, new acquaintances, or an approaching change; a friendly stranger usually promises gain and good tidings. A threatening or hostile unknown figure, by contrast, counsels caution against hidden adversaries.

Dream interpretation is for self-reflection and entertainment — it is not a medical or psychological diagnosis.
