To see a sweet potato in you dream, can be interpreted as symbolism of psychic and emotional energy associated with instinctual biological drives. If you eat sweet potato in the dream, then it means that your sexual appetite is stronger than the person that you are with. If your partner is eating sweet potato, then it means otherwise – your libido is lower. In both cases, sweet potate shows demand of balancing relationship. You need to find compromise within some aspects of yourself in order to make the relationship comfortable and satisfying for both.
