...Practicing tasks while lucid dreaming?

If people are said to be able to practice tasks while lucid dreaming, could it be possible to practice how to lucid dream WHILE in a lucid dream?

Does that get too meta for the mind to comprehend? Has it even been tried before??

And is it possible to distort time to such a degree as to even spend DAYS within a lucid?

Sorry, I have a lot of questions. I haven't had a lucid dream in a long time and am just starting out. Maybe I'm being a bit too bold jumping right into the WILD/V-WILD technique... but I want to be able to induce a lucid dream practically at will. Is this feasible?


ALSO, if I may add, that even though I am new to WILD and lucid dreaming in general, but i find that I can consistently and actually rather easily attain the hypnagogic imagery, and more likely than not enter what i can only believe to be sleep paralysis (my whole body feels light, tingly, pulsating, wavy... is this right?) but then after that I cannot progress. I don't quite understand what people mean when they say "watch" it passively, it may be worth adding that I often become very aware of irregularities in my breathing patterns at this point and often lose the paralysis sensation as quickly as it came. Tried counting too, which helped sparingly.

you cant practice LD in a LD?, but you can act like your lucid dreaming
SP is whene you're no longer able to move

So wait, is sleep paralysis actually physically binding? I just thought it was the point where you lose prioperception and feeling in limbs. This is where I get to, but when i become aware of this fact I find I either:
a) Notice my breathing/inhale too sharply/deeply etc., breaking the sensations
b) become too self-aware of the paralysis and my mind falls back/loses focus > losing paralysis

And what I mean by practicing a LD within a LD, if you understand the processes necessary for inducing a lucid dream, what is to stop someone from practicing those processes within a lucid dream? Perhaps there exists a barrier or a limit? (I like to think that within dreams, boundaries are imaginary) Or could you use this to become even more lucid within your dreamstate?

If only you could spend days within a lucid... but I don't think time distorts in a dream. Especially not when you're lucid...
But, practicing lucid dreaming IN a lucid dream certainly sounds amusing. But, you'd need a task to do in the deeper LD as well.
I've found that I constantly need something to do or pay attention to while I'm lucid dreaming, otherwise I wake up.
So, as long as you have a tight plan, you should be good.
