Dream meaning of canteen

Dreams of a canteen symbolize a need to keep emotionally hydrated and creatively juiced.
If the canteen is full, you are capable of quenching your own thirst and tending to your own needs.
If the canteen is empty, you are going through a creative dry spell, processing feelings of lack, and you are thirsting for acceptance, support, and/or creative inspiration.

To see or use a canteen in your dream suggests that you are looking to easily and conveniently satisfy your emotional needs.
