Recurring dreams, especially those involving being chased, often symbolize feelings of anxiety, stress, or unresolved issues in your waking life. The large black snake in your dream could represent a significant fear or a threat that feels overwhelming. Snakes are frequently associated with transformation and change, but in this context, it may indicate something you are avoiding or need to confront.

The park setting with the pavilion could suggest a place of refuge or relaxation that you feel is being invaded by this fear. Climbing onto a chair to escape may indicate your attempts to find safety or a higher perspective in your life when faced with challenges.

Since this dream recurs, it might be beneficial to reflect on areas in your life where you feel pursued by problems or fears. Consider journaling your thoughts and emotions related to these dreams and exploring what the snake might represent for you personally. Facing the fear represented by the snake, rather than avoiding it, may help to lessen the recurrence of this dream. Additionally, if you find that these dreams are causing significant distress, discussing them with a mental health professional could provide more tailored insights and coping strategies.
