Dream Coincidence

Two nights ago, I had an elaborate dream about a brutal Aztec or Mayan Warrior Lord. I remember watching him in a shallow pool of water, perhaps a swampy, river runoff area, and the tribe he was up against sent its men, one by one, to battle him. Each one that approached him did so in terror, and he basically hacked them to pieces with his weapon, leaving body parts and so forth in the water. (I watched this as if I were there, but nobody knew I was there...almost like watching a movie play out.) After all of this, he somehow approached me and confided in me what route he was was planning on taking in order to conquer other lands and tribes. When I found out where his "path of terror" would lead him next, I plotted it out on a map, and while the map didn't resemble any I've ever seen of the world, it was apparent to me in the dream that it was South America. My dreams are sometimes vague feelings, rather than definite shapes and symbols, and so when I tried to recall his name the next morning, the only thing I could piece together was "Nozca."

Today, I was working on a Geology lab involving plate tectonics, and I had to look at a plate boundary map of the world. All along the west coast of South America, (in almost the exact same S-shaped pattern that I plotted out for the path mentioned above,) there is a plate called the "Nazca Plate." I'm trying to remember if I looked at this map earlier in the week, but I know that if I did, it wasn't for more than a few seconds. So, it's odd to me either way that 1) If I didn't see the map at all, then wtf? 2) If I did see the map, it's pretty incredible that my brain can store something that insignificant and trivial and bring it back up in such a strange format.
