I had a dream that my brother was a baby and he was drinking vodka
Seeing your brother as a baby in your dream could represent his vulnerability or dependence on others. Meanwhile, vodka is a widely known alcoholic beverage that can signify stress or a desire for escape from reality. Drinking vodka in a dream could suggest that your brother is trying to find ways to cope with difficulties or problems in his life.
It could also indicate that you are concerned about his well-being, and the dream is a manifestation of your worries about his behavior. In any case, this dream is most likely a reminder that you should pay closer attention to your brother's emotional state and offer your support if necessary.
