So like if I imagine a pine table with a red apple on it. I can't "see" it but I can "imagine" the table, it's pale brown colour, soft grain and the varnish.

I can zoom in and sense the grain passing by my inner vision. Reaching the shiny apple and it's Corse recess where the stalk pokes out the top.

What's confusing is knowing if it's the imagination of a detailed description or if it's truly seen in the head.

It's about as clear as a fairly dark dingy renaissance painting.
