Dreaming of paper typically symbolizes your commitments or promises. If you see yourself writing on paper, it may indicate your ignorance or betrayal towards others. This suggests that you might be failing to uphold your promises or being unjust to those around you. The presence of paper in your dream serves as a reminder to be mindful of your responsibilities and relationships, urging you to move forward in the right direction.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Paper" (page 318).
A sheet of paper in a dream represents an oath, a vow, or a pledge. Writing a note on a piece of paper in a dream means being ungrateful and perfidious toward others. A writer in a dream also represents someone who is burdened, pressured, doubtful and uncertain, whereby, writing has become his escape goat and a way out of his depression. If one's boss gives him a paper to write something on it in a dream, it means that he will solicit something from his boss and eventually receive it. If one feels uncertain about some people then sees himself holding a pen and a piece of paper in a dream, it means that his obscurity will be replaced with clarity. Holding a piece of paper in a dream also means attaining one's goal, or completing a project, or finalizing a program. A paper salesman in a dream represents someone who helps cunning people do their tricks. (Also see Notebook; Paper; Write; Writer)
