"Some cases I know about from personal observation involve disturbing sleep cycles so much in pursuit of lucid dreams that the young people failed in work environments or crashed and burned in their university studies."
That is laughable ignorance my friend. The Wake Back To Bed method might mess your sleep schedule up a little, but you're only supposed to be up for about 30 minutes or so then you go back to sleep. That's not even the most common way of lucid dreaming. To say people have ruined their lives trying to lucid dream is, frankly, completely ridiculous and I'm embarrassed for the HN community for upvoting this post.
It wouldn't be too far of a stretch. Starting simply with the knowledge that dreaming happens while in REM, someone could find it logically to switch to an Uberman-type Polyphasic sleep schedule, since one of the biggest advertised advantage of such sleep schedule is dropping into REM a lot quicker due to exhaustion. If Uberman doesn't actually help them in terms of the sleep they need, but they also don't want to give it up, hoping to get all that lucid dreaming, a student could continue it for a a few months, which coincidentally is a school semester. Now you've got a student who is really burned out, and once exam time will crash and burn. Depending on the program, university they attend, and the person themselves, failing a semester could really screw them over one way or another.
For me, the Wake Back to Bed, when it does work, generally involves first the 30 minutes staying up, then 40 to 90 minutes of lying awake in bed before falling asleep. So that does unfortunately mess a bit with the sleep cycle, even though it should be just a blip in the radar in theory. Haven't managed to get any other method to work reliably. I guess what works and how varies by individual.
