I sawa black mouse without a fur in my dream for a brief moment and I commented how cool he is.
Dreaming of a mouse can symbolize fear, timidity, or being insignificant. The fact that the mouse is black and without fur could suggest that there is an aspect of yourself or a situation in your life that may feel dark or unfamiliar. However, your comment about how cool the mouse is could suggest that you are willing to embrace this unknown aspect and find value in it. It could also mean that you are overcoming your fear or anxiety about this particular situation.
