Just speaking from personal experience, I've never experienced time distortion in my dreams as extremely as you describe. I've experienced moments scattered throughout narratives that would take longer than 20 minutes to elapse in real life, but since I never recall experiencing every single moment of those narratives, I wouldn't assume my sense of time had altered while dreaming. Maybe I'd just skipped around, experiencing only 20 minutes' worth of the dreams' narratives, or maybe I'd only imagined those moments as joined by an implicit narrative and not really experienced time passing during any one of them. I'd love to see empirical research on this, but it's somewhat hard for me to imagine how reliable information on these matters could be collected.
The duration of REM sleep is more objectively observable than the contents of dreams; I was surprised to find that Google produces a reference immediately in response to the query, "duration of rem sleep":
The first REM period of the night may be less than 10 minutes in duration, while the last may exceed 60 minutes. [Stevens, 2013]
While cognitive function is clearly different while dreaming, I'm unaware of any evidence that it's enhanced in any ways that would be desirable during wakefulness. If you or anyone else can find any references to support your ideas, we could probably have a much more productive discussion here. Similarly, I'm skeptical of the comparisons of lucid dreaming to hypnosis and intoxication. These may be very different states of consciousness, and I definitely wouldn't call them "higher states".
Just to preserve the coherence of your response to my answer, here's the old content worth keeping:
Lucid dreams are by definition both conscious and occurrent during sleep, therefore:
- It's not logically possible to have a lucid dream while awake. If you're trying to refer to a similar state that is not a dream, please define it directly rather than by analogy to a dream state.
- Lucid dreams do not need to be brought to the boundaries of consciousness; they occur within those boundaries by definition. Maybe you mean to ask for ways of making ordinary dreams lucid.
The old "Let me Google Scholar that for you" offers plenty on lucid dreams and means of induction. I'll even copy, paste, and format some below...(I'm absolutely not vouching for their scientific validity BTW. "Medical Hypotheses"? Sounds legit...) Looks like there are about 2,878 more where these came from.
