Losing Teeth, Grabbing a Demon

It's another one of those dreams where my teeth are falling out. Very vivid - there's no pain but a definite physical feeling of my teeth coming loose, breaking apart, and being spit out of my mouth in chunks. The pieces of tooth are marbled in color, reminding me of polished rocks or the appearance of a sliced mushroom.

I'm conscious of dreaming here.

I look up and see some kind of demon-animal, vaguely catlike in shape but closer to the size of a large dog. It has a scaly body and sharp, pointy teeth. I say to myself, "If this is a dream, I can touch this creature with no harm." And I do. There's a slight tingling sensation as I touch the creature, but no pain. And then I wake up.

Why do better images look worse?

Why is it that higher-quality video sometimes looks inferior to people? My theory is that when improvements in quality (resolution or framerate, for example) are incremental, your brain compares the new, upgraded image against the previous iteration, comparing like to like. But when there's a sudden, dramatic jump in the quality of the image, your brain discards the old standard of comparison, and instead judges the image against reality, or against imagination, and the image inevitably suffers.

OTOH, there's also the element that higher-quality images make defects more visible, and any change in the medium requires artists (e.g. video directors and editors) to adjust.

I'm a layperson with no particular expertise in video or digital imaging, but this sort of question intrigues me. Thoughts?
