Dreams are how the brain processes emotion and memory at night. When a feeling — anxiety, regret, fear — is not fully processed while awake, it returns in symbolic form during sleep. Roughly three causes: a persistent stressor (work, relationships), unfinished business (words left unsaid, goals unmet), and mild trauma flashbacks. The repetition is the mind's own way of "urging you to face it."
Being chased: often maps to a sense of losing control and avoidance; what you flee is usually a problem you dare not look at directly.
Exams or being late: maps to "being-evaluated anxiety"; even years out of school, fear of "not being good enough" still enters dreams.
Teeth falling out: often tied to image, expression, loss of control; can also be a bodily signal from clenching at night.
Back at school: a metaphor for "unfinished business," a knot from some phase not yet truly turned over.
① Record. Note the dream and that day's mood on waking; their common thread often reveals what the dream points to.
② Don't avoid the issue. For the real problem the dream points to, try one small step in the daytime — even just admitting "this unsettles me."
③ Ease the pressure. Long-term stress makes recurring dreams more frequent; regular sleep, exercise, and relaxation often help. Treat it as a messenger, not an omen.
