I also agree with those who say that sleep has multiple purposes. REM sleep typically starts four hours into a sleep cycle, after the “deep cleaning” work seems to be done. This would suggest that the brain is prioritising its basic functioning over the discovery of unconscious patterns, which is, I believe, a sensible trade-off. It is not imperative that we spot our unconscious patterns, though in the long run, it can make a big difference to our lives.
- tuumi 2y agoREM sleep takes place much sooner than 4 hours. It takes place at about 90 minutes of sleep. And, hopefully, the sleeper goes through several cycles throughout the night. I would be screwed if it took that long to get to REM as I wake up 4-5 times a night.
- FailMore 2y agoSorry, you are correct. However when it first takes place, when there is more “deep sleep” work to be done, it is very brief, and becomes the more dominant aspect of sleep after that work has been done: https://upload.wikimedia.org/wikipedia/commons/thumb/3/3e/Sleep_Hypnogram.svg/391px-Sleep_Hypnogram.svg.png https://upload.wikimedia.org/wikipedia/commons/thumb/3/3e/Sl...
