Dreams involving holy water can symbolize purification, healing, or spiritual cleansing. Pouring holy water into a cup may indicate that you are seeking to nourish your spiritual self or seeking clarity in a situation in your life. It could also represent a desire to bless or sanctify something important to you, whether that be a relationship, a decision, or a new endeavor.
Consider what aspects of your life may need healing or renewal, and reflect on any spiritual practices you might want to incorporate. The act of pouring could also suggest that you have the power to bring positivity and blessings into your life or the lives of others.
Think about your feelings during the dream and any specific situations in your waking life that might connect to this imagery.
