So, how do we make and understand metaphors? This might look familiar. The first step is pattern recognition. Look at this image. What do you see? Three wayward Pac-Men, and three pointy brackets are actually present. What we see, however, are two overlapping triangles. Metaphor is not just the detection of patterns; it is the creation of patterns. Second step, conceptual synesthesia. Now, synesthesia is the experience of a stimulus in once sense organ in another sense organ as well, such as colored hearing. People with colored hearing actually see colors when they hear the sounds of words or letters. We all have synesthetic abilities. This is the Bouba/Kiki test. What you have to do is identify which of these shapes is called Bouba, and which is called Kiki. If you are like 98% of other people, you will identify the round, amoeboid shape as Bouba, and the sharp, spiky one as Kiki.
