What Does Dreaming of a Teacher Mean?
Traditional Interpretation
In the tradition of Ibn Sirin and al-Nabulsi, seeing a teacher in a dream can indicate knowledge, being led to the right path, and spiritual guidance. The knowledge the teacher imparts may signify wise counsel the dreamer will receive in life, lawful earnings, and a turning back from error; the teacher's approval can be regarded as blessing and esteem, while his anger may be taken as a sign of a neglected duty or a warning.
Psychological View
In modern psychology, the teacher figure can often represent the inner "sage/guide" archetype, our relationship with authority, and the need for growth. This dream can indicate that you are searching for direction in life, that you are ready to mature in some area, or that you are still inwardly seeking the approval of an authority figure from the past — a parent, or a real teacher.
By Context
For Singles
Seeing a teacher can indicate that a mature decision about life or an auspicious acquaintance is drawing near — that a guide who will show the right path will enter their life.
For Married People
It can indicate a period in the family calling for patience and instruction, a responsibility concerning the children's education, or growing mutual understanding between spouses.
Receiving a Lesson/counsel from the Teacher
It may signify that you will soon gain valuable knowledge, a warning, or experience that will serve you well — and that you will turn to the right path in a matter you have neglected.
According to Ibn Sirin, Being a Teacher (seeing Yourself Teach)
It can indicate that you will be of benefit to those around you, gaining esteem and respect — and that a leadership or mentoring role you take on will bring good.
An Angry / Scolding Teacher
It can point to a neglected duty, a reckoning of conscience, or the inner criticism you direct at yourself; it may be a call to re-examine yourself in some matter.
