This is going to sound weird (cause it does to me)... a while back there was a one hair in my eyebrow that was really bothering me. It was thicker than the others (hairs that seem too thick tend to bother me). But this one was different. When I brushed my finger across it- I could literally hear the hair make a clicking sound (not sure if clicking is the right word, but I don't really know how else to describe it). Every time I touched it, I could hear a click in my head. If I touched any other hair- nothing. All the other hairs were just normal-I didn't hear anything. I touched it again and again- same thing. I could hear just the slightest click. Needless to say, I pulled it.
