To dream of drinking vodka represents a wish to feel good not having to notice something. Trying to enjoy yourself while being willfully blind to a problem. Dangerously aware of yourself pushing the limits.
Negatively, vodka may reflect your attempt to feel good ignoring problems. A risk of going overboard having a good time neglecting to address or discuss something important. Feeling good while being aware off yourself ignoring a responsibility. It may also reflect pushing your luck with a relationship.
Example: A young man dreamed of drinking vodka that would end up causing a bomb to go off if he drank too much. In waking life he was having serious trust and relationship issues with a girl he embarrassed and trying his hardest to feel good around her while not calling attention to the problem. This neglect destroyed the relationship.
Example 2: A woman dreamed of drinking vodka from a red shot glass. In waking life he was very unhappy with her husband and trying to enjoy herself behind his back without going too far with it.
