  1. A tree falling in the forest generates vibrations, and that’s all we can say. Our senses detect the vibrations and our brains interpret them as sound (or even feeling, if the tree is big enough). For some people with a rare condition, vibrations generate mental images; they would perceive the falling tree as a visionary stimulus. “Sound” and “vision” are only in our heads.
