Usually, dreaming of bottles indicates celebrations and joy, although there are variations for this dream. For example, when the bottles appear filled with a clean, clear liquid, its a good dream that announces that all existing problems at the time will soon be solved and you will find new and advantageous opportunities and relationships. When the bottles appear totally empty, and if they are dirty this signal is worse, it is a warning that your problems will start to get worse. Dreaming of broken bottles indicates failures and sentimental losses, a failed business, problems at work, etc.
