This type of dream may reflect your subconscious awareness of potential threats or challenges that you are currently facing or anticipate encountering. It could also suggest that you are feeling vulnerable and seeking ways to defend yourself emotionally or psychologically. Pay attention to the specific circumstances and actions involved in the dream, as they can provide further insight into the areas of your life that require safeguarding or where you may need to assert yourself.
