In this dream, the spiders are fighting on the back of your neck, a vulnerable and sensitive area. This could suggest that you are feeling overwhelmed by a conflict or struggle in your waking life. The fact that there are two spiders could represent a duality or opposing forces at play. It could also symbolize a power struggle between two people or aspects of yourself. The location of the fight on your neck could indicate that this conflict is causing you physical or emotional discomfort. It may also suggest that you feel like you are carrying the weight of this conflict on your shoulders. Alternatively, the spiders could represent hidden fears or negative thoughts that are causing tension and stress in your life. This dream may be a reflection of your subconscious mind trying to process and resolve these inner conflicts. It could be a reminder to confront and address these issues in order to find peace and balance in your life.
