In general: Stranger in the dream embodies what was hidden up to now from the dreaming or what he has hidden deliberately. On this occasion, it could concern occult knowledge which is accessible only insiders, but also around information which the dreaming needs only in stress situations. Psychologically: If the dreaming of the stranger is aware in his dream, he should try to find out whether it threatens him or is, however, something that he should understand and know. Importantly less the information itself is the kind than rather as the dreaming handles with her. Spiritually: The mysterious - or occults - remains unknown so long and incomprehensible, until the dreaming raises the courage to put to himself him. This is in the dream lighter possibly as in the real life.
