I find that examining the scenery can be amazing. The quality of the texture of brick, wood, concrete, asphalt are unbelievable. There are so many irregularities, the texture is so lifelike. A wall of trees in the distance. If I focus on these things and fully appreciate the quality, it is an ecstatic experience in itself. Especially during high lucidity when I can fully appreciate that I'm looking at a product of my own mind...

There are tons of things you can do with people. Find some who are "powerful", if you got control. Several days ago I was in a high lucidity dream where I got to a lucid museum and briefly spoke to a curator. He told me "it's what you do with this stuff in real life what matters", or something along these lines.

There are forms of physical control that involve going through walls (glass is easiest) that I find invaluable in changing scene quickly. They do not require much control to execute. Climbing, while lacking grace seems to work reasonably well even at lowest lucidity.
