But it might be that rehearsal enough before you go to sleep is enough to help cue you to that repeated nightmare, remembering what the nightmare is and then figuring out how to cue yourself to do something different.

The evidence is convergent. Multiple independent sources reach the same conclusion, the underlying mechanism is well-characterized, and even the field's most cautious voices treat it as worth doing.

And I think what they had people do was either cue themselves to a particular smell or tone in wakefulness then to try and recall a recurring nightmare. Then during the night sleep, they had the tone playing in the background which would then cue them to the wakeful state-- they're still asleep, mind you, but in the pseudo lucid or lucid state, and then try and change some variable as you're describing.
they were rehearsing the alternate ending but about every 10 seconds they were playing them this very pleasing piano chord in the background and they were just bonding the association of the new outcome ending to the nightmare with this Pleasant piano chord and then sure enough in the subsequent weeks afterwards Not only was that person day after day doing the diligent therapy practice of rehearsing the memory whilst the piano tone was playing but then at night they would wait until they went into REM sleep which is the state we think the emotional therapy begins and they would start to Replay that same piano chord over and over again
those people who did that plus the memory reactivation at night it drove it from 66% all the way up to 92%
10 minutes of bright outdoor light within the first hour of waking anchors the circadian phase and improves sleep onset that night.
Morning sunlight exposure shifts the cortisol awakening response forward, improving daytime alertness.
Long-term morning sunlight reduces age-related macular degeneration risk.
Sleep regularity predicts all-cause mortality more strongly than sleep duration.
Tracking deep sleep on a wearable accurately reflects EEG-measured slow-wave sleep.
Caffeine has a half-life long enough that consumption after 2pm measurably degrades deep sleep in slow metabolizers.
