Rules for Posting Guides on Our Community
1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.
2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.
3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.
4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.
5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.
6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

How does your brain know when the end of your sleep is?
Is your brain a separate entity? You literally decide when to wake to with alarm. Or if you don’t set a time, it wakes you after x hours, after it’s backloaded all the REM.
If sleep deprivation gets too bad, it’ll completely knock you out to get as much REM in as it feels you need to function, alarm or no alarm.
Studying neurobiology/neuroendocrine systems is a great way to question who really is in charge.
It's a lot of work man. Just being human. A lot... of work...
Billions of years of evolution
So it just anticipates when my alarm is about to go off?
It could be you subconsciously thinking about it because of anxiety. It happens to me sometimes.
That keeps me from going back to sleep all the time. Like oh I have another hour? Then it's 30 minutes to fall back asleep and then that's only 30 minutes so better I just get up. I get tired by the end of the day a lot lol
Weird polyphasic sleep schedules take weeks to start working, so probably from patterns. Although if what op comment is true something else is happening too
