Offcourse they are. But even these random images work as methapors of how you are. Even if those maybe arnt that important, i have to see after i know the understandig of a dream. So if i dream about a car i really want to know why i did it, to understand more of myself and whats going on on a deeper level of my thinking self.
Its strange, to try to know one self could be a so big task. Like it shouldt be enough to know every other thing here i the world.
