And I have posted once more (well, did so ten or so hours ago). 

Huh, and I sure can type a lot without really noticing it, looking at my last ooc-post. On another random note on the last topic, I am somewhat inclined to relate dreams to our ability to imagine, or more specifically visualize things and recall what something tasted, smelled or felt like - which could give some explanation to why dreams came to exist in the first place. (I tend to maintain that while there is always a complete and logical explanation to [i]how[/i] everything works - furthermore an explanation which does not require weird exceptions to the laws that govern everything else -, there might not always be a reason [i]why[/i] something came to exist besides a long row of coincidences.) 
As I noted earlier, I usually kind of start dreaming before I fall completely asleep, and on those occasions, I both see and feel the dream and can also still feel my body until at some point I fall completely asleep and the sensory input can no longer be consciously detected and the knowledge of being about to fall asleep fades off. Now, when I think of it, then the most vivid visualizations and "conjured" sensations have felt somewhat (remind you, I am both naturally good with visualization, and have been actively practicing sensory- and body-control for a rather long time) ... similar, minus the obvious difference of in one case the experience being formed by the subconsciousness with the conscious part being just an observer, whereas in the second case the conscious mind is [i]both[/i] the creator and the observer. And in lucid dreaming, the distracting sensory input is still off as it usually is while dreaming, you are aware of the experience being a dream and (in many, but not all cases - some apparently just know they are dreaming and wander about with that in mind, but cannot really alter the surroundings and happenings at will?) the conscious mind can override whatever the subconsciousness has given form to. 
 - I could give a fairly good explanation to how dreams are produced on the biochemical level (as well as some related phenomena being explained as an extension of it), and I have seen elaborate works on how dreams, visualizations and sensory input can be observed as brain activity and[i] vice versa[/i] (to the point that brain activity has actually been translated back to a blurry version of the image the person was trying to visualize) - and from there I would say that these things very greatly do overlap - but I haven't really seen anyone reliably try to analyze the overlappings more specifically. 

- The rune mage has the runesword on his back, right, or am I just making an assumption here based on another rune mage? And momentum is still a problem for the wielders of such, even if the weight isn't? (Although arguably, the weight of your own body still tires you to hold up - just try holding your arm horizontally to the side for five minutes or so) ...How [i]can[/i] they get the runeswords off their backs at any reasonable speed, or attach those on there? Or how do they sit or run with those there, for example? Historically swords weren't really kept on the back for a significant number of reasons...
