Not really related but your mention of seeing "patterns" had a sort of example that happened to me early this morning when I looked up into the dark night sky from my back porch, there were stars and constellations there that I had never seen before? Wtf? Anyway I kept looking and then realized that my mind had made or filled in that sight with the explanation of never before seen stars, being that they turned out to be just reflections from my nearby outside lights on the few remaining and upper leaves on my tree where it was hitting at just the right angles to appear as stars was what I was really seeing.
