Hehe, regognize it. One time in a dream me and a friend were badass gansters, and we randomly shot a guy eating breakfast because we were evil, and he didn't even notice. The bullet just stood in there, and he went on making breakfast, and neither him or us cared at all! But I've also had dreams where I've mindlessly thrown a grenade into a mass of people (classmates and such), and then I was like "nooooo, what have I done!!" while crying, even when they all get up unhurt and ignore the explosion as if nothing had happened... weird how things don't make sense in our dreams huh?
