When I imagine something (with my eyes closed, before I fall asleep but after I have started the process of trying to) I see it in my "mind's eye." But I'm not able to reproduce it exactly. It reappears from different perspectives, at different scales, sometimes overlapping or changing but rarely in motion: more like a series of slides projected irregularly onto the screen. Edges are fairly clear, colors and shades not very clear. The speed at which these images are generated based on my effort to direct them is astonishing, compared to how long it would take to create a similar image by hand, or in Photoshop. In the background, dark blue afterimage-like flashes play against a dark grey surface.
Here I have tried to render the image from yesterday's entry as I might picture it in my mind's eye. I am restricted by the format to a rectangular still image. It ought to be rotated at some odd angle and distorted in scale, but I left these things alone so that it can be more easily compared with the image below. It also ought to be darker than is shown here, but even as it is you may need to adjust your monitor to see it at all. Also, the edges are usually lighter than the background, rather than darker as shown here. I'd be interested in hearing if other people's experience of the "mind's eye" is similar, or seeing their attempt at an accurate (rather than poetic) representation.
