Dreaming of a shadow can symbolize the unknown or hidden aspects of your subconscious mind. The fact that you can only see fingers in the shadow could represent a sense of powerlessness or lack of control in your waking life. This could be related to a situation where you feel like you have limited options or are unable to fully grasp a situation. The red wall in your dream could symbolize intense emotions, such as anger or passion, that are being repressed or hidden. This could suggest that you are suppressing your true feelings and they are manifesting in your dreams. Alternatively, the red wall could represent a barrier or obstacle in your life that is preventing you from moving forward. The combination of the shadow and the red wall could also suggest a fear of the unknown or a fear of confronting your true emotions. It is important to reflect on any current challenges or conflicts in your life that may be causing these feelings. Consider finding healthy ways to express and address your emotions in order to overcome any obstacles and gain a sense of control in your waking life.
