To see a drain in your dream, signifies your need to release and channel your emotions. You should not keep your feelings inside. Consider the condition and appearance of the drain for clues on how you are feeling. Alternatively, it may represent some wasted effort or loss. The dream may also be a pun on something or someone that is "draining" you of your energy or resources. To dream that you are unclogging the drain, indicates that you need to remove some obstacle or blockage that is hindering your progress.
