I voted a 10. When I become very Lucid, the constructs around me are just as real as the waking world, albeit I know it's a dream. The only differance is the fact that I know it's a dream, and can alter it as a result.

But things like texture, color, weather, etc, are all just as real. That is one of the things I marvel at most when I dream, being able to reach down and feel the grass under my feet, the bark on a tree, the texture of a drywall on a building etc.
