To dream of a bottle of liquid or a drink represents an opportunity to do something whenever you want. Having a chance to do something your way, enjoy yourself, or quickly fix a problem.
To dream of an empty bottle represents a total lack of opportunity. You may have used up an opportunity or feel that nobody will give you one. Failure may feel inevitable. It may also reflect feelings of knowing you can do something whenever your want without knowing how you would.
Example: A man dreamed of seeing a red empty bottle sitting on a shelf. In waking life he was suicidal without knowing exactly when or how he would go about killing himself.
