If I had a good dream and suddenly woke up. I can get back to sleep and continue the dream and somehow manipulate the story while I'm in it. It's very weird, usually i know immediately when I'm dreaming while it's happening and I can wake up if it's not interesting. I don't have real nightmares, because I can wake up, since I realise it's not real. There are only 2 times that i remember that i didn't realize it. ( One quite embarrassing one). One time when I had a fake wake-up ( i thought I woke up for real and the feeling afterwards that something was off was really weird. Since I already thought I woke up). After a while, i woke up for real ofc, not by my doing. Another time i needed to go to the toilet and i couldn't. So i tried harder... Yeah, quite embarrassing this one, 10 years ago after a night of going out pretty late... I do think I'm having less dreams lately. Since I never have the need to try to fetch the dream again. But I'm using my alarm clock again and perhaps that's related. Fyi, i forget about the dream immediately after standing up. It's possible that I talk in my sleep, i once woke up during that and had a conversation with my girlfriend before I woke up. Somehow my dream was a visual interpretation of what she said ( while my eyes were closed ofc) and I was way more open than i usually am. She could have asked me anything and I sincerely doubt of i would have been able to dodge a question if I would have wanted that. Ps. I'm a very irregular sleeper. I can only sleep 3-4 hours and it's almost all REM/deep sleep according to an app that i placed on my bed. Ps2. If you have trouble waking up. Set a hard noise 10 minutes before the desired time ( 1 second duration), you should get up more easily when the real alarm goes off.
