Recurring dreams often indicate unresolved issues or emotions in your waking life. In your case, being chased by a large black snake could symbolize a significant fear or anxiety that you feel is pursuing you. The snake itself may represent something in your life that you find threatening or overwhelming, possibly related to personal challenges or deep-seated emotions.

The setting of a park with a pavilion suggests a place of relaxation or enjoyment, contrasting with the fear you experience in the dream. This could indicate that you are feeling a lack of safety or comfort in areas of your life that should be peaceful.

The act of climbing onto a chair to escape may symbolize your attempts to rise above your fears or to find temporary refuge. However, the fear of being bitten and dying might represent a deeper concern about facing the consequences of confronting these issues.

To gain further insight, consider reflecting on any current stressors or fears in your life. Are there situations or emotions you are avoiding? Addressing these fears directly in your waking life may help alleviate the recurring nature of the dream. Additionally, keeping a dream journal to record your dreams and any related thoughts or feelings can provide further clarity over time.
