Good points, but;

• I have plenty of time to think and don't feel like I'm in any rush. Sleeping is time off.

• I've been pleased by my mind's acuity under some very adverse conditions indeed. And terrified by its fragility on other occasions (forest rave a couple of months back, not pretty). But dreams are too far removed from reality to be much use in training myself. Like I said - as soon as I become lucid (or at least aware that I'm dreaming) things stop being interesting.
