Interpretation 1 — Theresa Cheung
A dream that plunges you back into your childhood or an earlier stage of your life may indicate nostalgia for happier times or regret for the lost years. Alternatively, your dream may be urging you to recapture the high spirits and optimism of your youth, or be reminding you of an important lesson that you learned at that time but seem to have now forgotten.
If your dream sent you back to a period of your life that was unhappy, the purpose may have been to help you re-examine and resolve your emotional baggage.
