Dreaming of being in a deep pool of dark navy blue water can symbolize deep emotions or subconscious feelings that you may be grappling with. The water often represents your emotional state, and the darkness can indicate feelings of uncertainty, fear, or being overwhelmed by these emotions.

Treading water suggests that you are trying to stay afloat amidst these feelings, indicating a struggle to maintain control or balance in your life. The absence of a ladder and high walls may reflect feelings of entrapment or a lack of options in a situation you are currently facing.

This dream might be prompting you to explore what emotions you are dealing with and to seek ways to address them. Consider what aspects of your life make you feel trapped or overwhelmed and think about how you can find support or solutions to rise above these challenges. It could also be helpful to take some time for self-reflection or reach out to someone you trust to discuss your feelings.
