That's a good description, and seems to align with what I think I feel - a sensation, I tried to think of examples that weren't images for me, but just a sensation, but I think, at least in my 30 second brainstorm, I always got an image, but it was always a very simplified one, and the more complex the idea, the shorter the sensation. This was not done scientifically at all, but what I'm trying to say is thanks: that's a pretty succinct description that I can get behind.
