Why won’t my “dream gun” work?

I have an old-style gun in a lot of my dreams. I can shoot at someone and the bullet will hit them but not do anything. I’ve had about 6 dreams with this gun and it’s never worked. In my もっと見る 最近 dreams I acknowledge that the gun has never worked. I‘ve killed people in my dreams using other things, but for some reason this gun that constantly shows up never works.
