Drinking a soda can be a sweet, refreshing experience.
In a dream, soda may refer to an event where you experienced a great deal of pleasure. Soda may also represent the need to quench your desire for uplifting fulfillment, or it may represent a refreshing idea. (See 71JP, Coca-Cola, Pepsi, Sprite.)
To dream of drinking soda (like Coke or Pepsi), suggests that you are seeking more pleasure or excitement in your life.
A sign of a contented life despite much labour.
