Recurring dreams often indicate unresolved issues or fears in your waking life. In your case, being chased by a large black snake in a familiar setting could symbolize a significant anxiety or stress that you feel you cannot escape from. The snake, often representing transformation or hidden fears, might suggest that there is something in your life that you are avoiding or not addressing, which may feel overwhelming. The park setting, especially with the absence of others, points to feelings of isolation during this struggle. Climbing onto a chair to escape may indicate your desire to find a safe space or a way to rise above your fears, but the recurring nature of the dream suggests that this fear or issue is persistent and unresolved. The fact that you wake up just as the snake is about to bite you could signify the urgency of facing this fear. It might be beneficial to reflect on areas in your life where you feel threatened or anxious. Consider what the snake represents to you personally—perhaps it's an unresolved conflict, fear of failure, or a significant change you're resisting. To address these recurring dreams, you might want to explore stress management techniques or speak to someone about the pressures you are facing. Keeping a dream journal could also help you identify patterns and emotions linked to these dreams, aiding in your journey to understand and confront the fears they represent.
