Areyona, your dream of visiting Japan and attending a concert where you felt carefree and happy is deeply symbolic and revealing. Japan, as a destination in your dream, represents a longing for new experiences, adventure, and a break from your current environment. It might symbolize a desire for cultural enrichment and a fascination with the unknown, which reflects a part of you seeking escape or new perspectives.
The concert setting where you felt immense joy and freedom indicates a deep-seated craving for emotional release and a break from the pressures you face daily. Concerts are often associated with communal experiences and shared joy, suggesting that you are yearning for connection and moments of pure happiness that are perhaps missing in your waking life. The feeling of being carefree and happy in the dream starkly contrasts with the frequent stress and anxiety you experience, highlighting a subconscious desire to reclaim joy and spontaneity in your life.
This dream could also be an expression of your inner self calling for a balance between responsibilities and pleasures. The carefree aspect of the dream suggests that your mind is seeking respite from the constant state of alertness and worry you often find yourself in, as indicated by your difficulty in falling asleep and waking up frequently during the night. Your subconscious is reminding you of the importance of finding moments of happiness and relaxation amidst life's challenges.
