Perhaps - as a discovery that has attracted no research in a century and a half, diagnosis seems unlikely. When I came across it a few years back it was a news piece about some university research into an unexamined phenomenon. That must have been Essex uni in 2015. It was only after that news piece I realised literally seeing images was even possible! I always just assumed anyone who spoke of "seeing" was just using a poor visual metaphor to describe something far vaguer. When I speak of visualising there is nothing I could call visual in proceedings, it's a feeling, a concept, a sensation. "I just know", and can sense and explore without seeing. Like the commenter I replied to, having heard of this thing I had to ask a selection of friends similar questions "so you actually see a ball?". Oh. Wow. Really? So then I wanted to know how vivid, how often, how controllable etc. It also blew my mind somewhat as I just assumed visual was entirely metaphoric. For me, it's not having a vague or ephemeral image and expecting something special or super realistic. It is being in a basement or coal mine during a power cut. Nothing. The mental cinema screen is firmly off. For all of my life. I have never once been aware of any visual aspect to any of my imaginings or dreams. Not even a sense of light or dark, colour or even some vague, blurry outline. The sense of 3d and spatial awareness and modelling isn't - for me at least - connected with an ability to create images. I seem able to do the former just fine, and the latter not at all. Yes, it does seem strange to be able to do the spatial without any visual whatsoever, yet it's consistently worked quite easily. Describing it adequately is far, far harder... :) |
