The blackboard sets information out in black and white, so in dreams it can represent unambiguous insights or the need to make your mark on the world. Because chalk can be rubbed out it is a warning against having rigid opinions that do not allow the possibility of change. According to Freud, holding a piece of chalk suggests masturbation whilst breaking a piece of chalk suggests a fear of castration. A school desk is a symbol of your most private self.
If your initials are carved on the desk, this also expresses your desire to make your mark on the world. Freudians would argue that opening a desk and searching inside is a symbol of sexual intercourse.
Many of us associate ink with our schooldays and if ink is spilled over a sheet of paper in your dream, this may suggest feelings of guilt. The shade of ink will be significant: black ink will symbolize evil thoughts or deeds, whilst red will symbolize impulsive acts. Dreaming of notebooks or schoolbooks can suggest a great deal; are the notebooks neat, suggesting an ordered mind or are they messy, suggesting confusion? If there are doodles alongside the scribbles, this suggests a creative personality that thrives in chaos. If, in your dream, your schoolbag is filled with pens, papers, books and apples, this suggests the happiness gained from happy experience but if the schoolbag is heavy and cumbersome, you may be feeling weighed down by the past. Pay attention to the quality and condition of the school bag as it could reveal a lot about your current approach to life.
