To see or carry a knapsack in your dream, represents your hopes, desires, and secrets. It may also be symbolic of the knowledge you have acquired over the years. It also signifies the emotional baggage and responsibilities that you are carrying and weighing you down.
To see a knapsack while dreaming, denotes you will find your greatest pleasure away from the associations of friends. For a woman to see an old dilapidated one, means poverty and disagreeableness for her.
