#2"Our findings demonstrate that reported sleep duration, but not subjective sleep quality is associated with both cognitive performance, especially in language subdomains, and white matter integrity of the SLF irrespective of age, sex, or BMI."

#3Oversleep can also be bad along some dimensions:
> For cognition only, associations shift to a negative association of sleep duration and cognition for participants sleeping more than 8 hr a day.
Though looking at the charts from the study I can say that Nassim Taleb would not be pleased with how weak the correlations seem to be:

Given that one of (emphasis one of) the reasons for long sleep duration is having poor quality of sleep, that doesn't surprise me. And if that is the only cause of negative correlation while other causes are harmless, that could also explain why this correlation is weak, no?

#5I have a very weird problem/issue, maybe someone can help.
In my school days I used to maintain a dream diary, where I would note down every dream I had after waking up. I stopped doing that when I got into college, but dreams never stopped and I never stopped analysing and trying to remember the dreams.
Fast forward to present time (10 years from school), whenever I want to wake up i.e. after 6-7 hours of sleep I can't stop myself from thinking about the dream. It's like I am in a half-awake and half-sleepy state and I can't control myself to get fully awake, I know for sure I am not lucid dreaming.
I wake up to turn off the alarm, but my mind rushes back to thinking about the dream (because 99.9% of time it is very interesting and it seems like I need to dive into it further to understand/remember it). This cycle keeps on continuing, I drift to sleep while thinking about the dream, and then when I wake up there is a brand new dream in my head, and I get back to thinking about it. This cycle keeps on going for 2-3 hours, so my total sleep time from an outsider perspective is 10+ hours.
No matter how much I think before going to sleep to not think about the dreams in the morning no matter how interesting they are, I am not able to control myself in thinking about the dream in the morning and then just falling back to sleep eventually.

#6Sleeps helps consolidate anything you learned during the day, since it helps forming long-term memories.

Put your alarm clock on the other side of the room.

I'm not an expert on this matter, but it seems that you primed yourself to think that to a subconscious level, maybe try to prime yourself to think about gratitude first thing in the morning, but you'll have to belive deep down that is true, useful and important otherwise those dreams will be more interesting to your mind.
Maybe you could start being grateful about the dreams and let them go, and focus on your body, be grateful you have two legs, you can breath... (find your own things).
Gratitude is not just contemplative bullshit, it can be about action, like OK I'm acknowledge all these good things I have, and I need to fight thermodynamics, taking action or they might go away, like are you grateful you have two legs, take the action of walking and so on, it can be about honoring those things we take for granted but we can lose.
I hope is not too cheesse or sounded crazy.

Are you having a form of sleep paralysis maybe? This "half awake, half asleep" state is one I know quite well.
Here's a variety of sleep paralysis symptoms I've experienced over the years:
- You're in the "real world", but you feel like you're not really awake
- Limited control over your movements; or extreme difficulty moving your limbs; or you "feel" like you're moving, but you're not quite moving (or not at all; kind of like you're swimming in tar)
- Extreme stress / nervousness, like something's wrong and you can't figure out what; panic even sometimes
- Manifestation of some phobia (spiders, insects, monsters) in your room / around you
- The last few moments, or last situation of your dream keeps repeating, like it's on a loop (you "wake up", think you're awake, and you're still dreaming)

You have to get up. Set your body on unreturnable path to awake.
