Alcohol
Alcohol stands for cheer, company and the release of feeling. Drinking happily with others means social fortune rising and good occasions arriving, and receiving a fine bottle means you will be well treated. Getting drunk and coming undone, by contrast, signals a need for restraint, and drinking alone means feelings you have not spoken have piled up. A drunkenness that will not lift is a caution that judgment has clouded.
Drink loosens the tongue well before it loosens anything else. Traditional reading took the wine of a feast as a good occasion, and drinking alone read differently. Who you drank with, and how, is the dividing line.
Readings by Situation
Drinking happily in company
Cups are going back and forth. Tradition read wine at a feast as an occasion for celebration, and since a drinking table is where things you normally keep in come out, the dream can also mean there is something you want to say.
Being poured a drink by someone of standing
A sign that someone who will help you appears. Tradition read a superior pouring for you as career fortune. It is also read as your position rising.
Drinking alone until drunk
A sign of something unresolved inside. Tradition too read drinking alone as worry. If you are actually drinking more lately, look at that first.
Making a mistake while drunk
The worry that words will get ahead of you. Read it as a sign there is something you need to keep to yourself. It is not a forecast that this will actually happen, so there is no need to fear it.
Drink dreams stand for company and occasion, so they are not a bad omen. Still, if drinking alone keeps returning in your dreams, look at how you have been feeling. If your actual drinking is rising, that comes first.
