Hey guys, new guy here. I have a few questions in general about lucid dreaming.
  1. Does the extent of dream control vary between dreams?
  2. Can lucidity be attained every night?
  3. Once lucid on any given night, can you literally do anything? The dream could begin on any subject, but could you, once lucid, simply throw it away and go somewhere else/do something else entirely?

I'm sure the answers vary according to the person, of course.

A little background:

I'm interested in improving my quality of sleep. Too often I find myself tiring during the day. Mentally. Of course, the 10th grade school schedule fights the biological clock, but there seem to be ways to improve sleep in general that, surely, can do nothing but good.

First that means exercise. Self-explanatory, already got that down. But what about lucid dreaming? It may not help my body rest more than it already does(?), but at least it will improve the quality of my sleep. On some level.

But that brings me to the questions about lucidity and its extent. I want to do extreme things. Crazy stuff, because it's fun. You know . . . nuclear bombs and whatnot.

. . . But is that possible during a dream about . . . *cringe* . . . school? Can I just leave, and go anywhere else, teleportation-like? Are there limits to what one can do while lucid?

Many thanks, guys!
