Dreams involving colors and liquids can often represent emotions and experiences in your waking life. The red liquid you were dropping could symbolize strong feelings such as passion, anger, or even fear. The act of dropping it into toilets might suggest a desire to release or cleanse yourself of these overwhelming emotions. Toilets are often associated with letting go or disposal, indicating that you may be trying to rid yourself of something troubling.

The transition of colors—pink and purple—can indicate a shift in your emotional state. Pink often represents love, compassion, or nurturing, while purple can signify spirituality, transformation, or deeper emotional understanding.

When you dropped the liquid into swimming pools, it might suggest that these emotions are affecting your social life or public persona. Pools are often associated with leisure and social gatherings, indicating that your feelings may be impacting your relationships.

Overall, this dream could be urging you to examine your emotional state and consider how you might be expressing or suppressing your feelings in your waking life. It may be beneficial to explore these emotions further and find healthy outlets for them. Consider reflecting on any current situations that might be causing you to feel overwhelmed and think about ways to address them.
