Did anyone else have trouble recalling the red vs blue sides? (based on my experience with this (below), it seems as though my mental association was essentially "top and bottom are same" and "narrows are same" but neither really had a color. When I close my eyes, I don't see "red" or "blue")

At first I was imagining a 1cm by 1cm by 4cm block. I then realized that getting the 16 cubes of 1cm each out of this wasn't possible and then went to the accurate idea of a 4 by 4 by 1. I realize I am having a great deal of trouble going from a 1cm by 4cm rectangle and then adding depth, while the 4 x 4 square I can add the 1cm of depth much easier. I can rotate the image of the 4x4x1 around in my head and yet cannot do the same with the 4x1x4 (despite the fact that I recognize that they are the same image).

Adding colors: four narrow are red, two fat are blue. Got it. Break it up into cubes.

1. Red and blue faces requires it touch the outside of the 4x4 square. 4 along top side, four along bottom side, and two each on the left and right (already counted the corners).=12 total red and blues.

2. One red and two blue... which ones were red and which were blue again? I know that the four narrows are the same and that the top+bottom are different... and just logicked that if the question is one red and two blue, that means the narrows were blue (the reds don't touch->top and bottom). To be two red and one blue... WAIT--that logicking doesn't work because the edges have Top side bottom. So I'll look back at which sides were which color. In my mind I just have "top and bottom are same color" but that's not assigned to red or to blue. Okay--top and bottom are blue. This means along the edge of the 4x4. uh... the perimeter again. So 4+3+3+2=12. Unless you're asking for two red and exactly one blue, in which case it's the corners... wait--two red? red was the narrow side color. i think i switched them again. Final answer: to have two red and one blue you must have two red, meaning the narrow side meets a narrow side, which only happens in four places. Four.

Just re-read the question. You asked for one red and two blue. All of them except the middle 4 blocks, so 12.

1. No painted faces? All of them are painted on at least one side: we painted three sides of the block, each of the 16 cubes we chopped the block into touched at least one side. 0 are completely uncolored.

Has anyone else with a similar level of mental imagery to Guy's had any experience with Lucid Dreaming/dream recall? Based on what I've read, it seems as though mental imagery is significant in the ability to lucid dream/recall dreams, but I haven't found much written on lucidity with little mental imagery.

Additionally, does this extend into the rest of your interactions with people? Do you confuse different people often? How well do you assign names to people? (would blonde, wavy hair, ~5'3", named "Alyssa" be distinct in your mind from the same traits, but named "Elizabeth"?)

Visualizing a family member, for instance: I personally have a similar experience to yours, Guy, and find that when tasked to form an image of a parent, for example, the person becomes a hodgepodge of significant traits at best and just hair at worst. My father, for example, is just a bushy mustache with short curly hair and my sister is a slightly open-mouthed smile. My mother is just an outline of hair... and it's the hair color she had ten years ago, but no longer.
