Going back to school you attended during childhood reflects the need to appreciate what you have (in this case, the accumulated knowledge). It is a throwback to the past, but it can help you understand the present. Not surprisingly, dreaming about the school may mean that you are behaving childishly. For this reason, the unconscious is returning you back to that time, reminding you to be over with that stage if you want to look forward and progress in life. School ultimately urges you to learn and accept the lessons of life. A teacher in this dream represents your own self-censorship and self-control. If the teacher scolds you it indicates that you feel guilty, or you consider yourself inferior compared to others, or your misdeeds will come to light. If the teacher congratulates you it means you trust yourself and your abilities. If you are the teacher of the school the dream portends good fortune. If you are a student you will suffer a setback in business; it will worsen if, in the dream, you forget the lesson.
