To dream of tomato soup represents a wish to keep a situation comfortable the way it is. Not wanting to lose warmth, love , or respect from those around you by trying to keep them happy by not changing something. Enjoying keeping special treatment or an easy situation exactly the way it is.
Example: A man dreamed of a big bowl of tomato soup being spilled on the floor. In waking life he was totally embarrassed by his son in front of the rest of his family after attempting to purposely delay giving his son money that was promised him because he didn't like the idea of his son moving away to another country once he got the money. The spilled tomato soup reflected the complete loss of the father's ability to feel good maintaining his lie to prevent any changes happening.
To dream of soup represents your feelings about a situation that you don't want to lose a good feeling about. Concern about keeping the warmth or pleasantness of something alive.
Consider the kind of soup for additional symbolism.
