For me, the encounters have been visions--no dialogue. I've been entranced by forms, colors, and geometries, but so far there has been no verbal language. That said, I kept my eyes open during a recent trip, and I spent most of my time looking at a massive tree in incredibly vivid detail. Though no words were spoken, I felt acutely aware of what the tree was, suddenly conscious of its inter-workings. The thousands of color patterns seemed to connote biological mechanisms. Not that I understood specifically, but much of the extreme variation in color seemed to represent water and nutrient flow, photosynthetic efficiency, etc.
