Drink / Drinking dream meaning is explained below using 1 different source. Each interpretation is shown with its source.
Interpretation 1 — Eric Ackroyd
If you are drinking usually this will mean your unconscious is offering you something which, if accepted, will improve the quality of your life.
If you do not, in the dream, accept the drink, make sure you do on the next occasion; or relive the dream, only this time taking the drink and swallowing it. In this way you may come to identify what it is that is being offered.
