You are right in the sense that the majority all share fear. However, our fears aren't all merely generated by our minds. Fears and phobias are genetically implanted, triggered by trauma, and other experiences that cause a scare. PTSD is an example of that.
Although our mind has the capacity and functionality to create new information, most of us can't access that 12-14%. Most people only function on about 8-10% brain power, and what we see in our dreams and nightmares are a compilation of faces/art/media we've seen consciously and subconsciously throughout our lifetime.
I don't necessarily thing we all recognize our mind as the source of fear, but we pinpoint it back to another experience and that's why it's specific.
