For the human mind, elements and/or phenomena that occurs in nature and that interacts with any of our sense excluding the so-called "natural senses" (those perceptions that come from vision: size, shape, color...) is very attractive because it appears to be sort of part of the unkown. My explainational theory of this events in the human mind is that because the eye gives us more different perceptual experiences than any other sense (and this is a FACT), and it is the most used of all the senses (another FACT), then, it is given more reliability, thus, it is believed that from the eye is from were we get our knowledge of the world, and, thus, when phenomena that is percieved through other senses (like sound, or heat), it is given a sort of mysterious nature, and is believed to be non-natural, and thus, non-scientific.
