This dream may symbolize a desire to reconnect with your past, specifically your childhood and old friendships. The setting of the dream, a school similar to the one you attended in 3rd grade, represents a time of innocence and simplicity. Seeing your current best friend, whom you haven’t seen in a while, may suggest a longing for the comfort and familiarity of your childhood friendships. Playing badminton with the other kids may symbolize a desire for carefree and playful interactions. However, the absence of your boyfriend may indicate a feeling of disconnect or distance in your current relationship. Your subconscious may be urging you to address this issue and reconnect with your partner. The appearance of the lady and the setting change to your classroom may represent a shift in your thoughts and emotions. The two girls who you never talk to in school may symbolize aspects of yourself that you have neglected or ignored. The book they have, which you mistake for a diary, may represent hidden thoughts and feelings that you are not fully aware of. This dream may be a reminder to reconnect with your past, reconcile with your present, and explore your inner self.
