What Does Dreaming of a Foreigner Mean?
Traditional Interpretation
According to the tradition of Ibn Sirin and al-Nabulsi, seeing a stranger (a foreigner) in a dream can often indicate unexpected news, a fortune arriving from afar, or a new person about to enter your life. If this unknown person appears well, it may be regarded as a herald of goodness and blessing; if they appear ill-natured or threatening, as a trial calling for caution, or an outside hand meddling in one's affairs.
Psychological View
In modern psychology (especially in Jung's approach to the "shadow" and the archetypes), the stranger in a dream can represent sides of yourself you have not yet come to know, have suppressed, or are just discovering. This figure may reflect that you stand at the threshold of change, that you need to step outside your habits, or a curiosity about a new identity you wish to bring into your life.
By Context
For Singles
Seeing a smiling stranger in a dream can indicate a new acquaintance arriving from unfamiliar circles, the door of fortune opening, or an encounter that will bring a breath of fresh air into your life.
For Married People
Seeing an unknown guest or visitor can mean news entering your family's life, an unexpected visit, or a blessing to be shared within the home; if the person seems uneasy, it can also be read as a call to let go of needless worries.
According to Ibn Sirin, Speaking with a Stranger
Conversing with someone you do not know may signify true news arriving from afar, useful information, or unexpected guidance that will show you the way in your affairs.
A Frightening or Threatening Stranger
Seeing a stranger who unsettles you or follows you may point to an inner anxiety, a matter you avoid confronting, or a situation in your surroundings that calls for caution.
