Ever since 2019, I've noticed I have been waking up in the middle of every night. Every night when I finally go to sleep and start dreaming, it would only last a few hours, and then sooner or later I come out from dreaming. I still feel tired, my brain knows to keep my eyes shut, and I'm still staying in bed, waiting to go back to dreaming. Before I could REM sleep (I think that's what it is) through the whole night, and would wake up in the morning after the sun rises. Nowadays this sleep-awake-sleep pattern keeps happening every night, usually between 4 - 4:30 am (I just figured out now as I'm awake typing this), and I feel I should be dreaming for the whole night and not just two separate times during each night.

Is this normal for people, especially adults or adolescents? Does anyone else have this similar sleep pattern where even once they go to sleep and dream, they'll stop dreaming but stay in bed with their eyes shut until they can go back to dreaming? I'm told this is normal, but I want to know if there's anyone else going through this similar occasion. Today I woke up because either my room's more cold than warm or because of my allergies (and the area I live in is making it worse), but now I finally figure out what time I would wake up first before I could reach sunrise. I'm gonna go try to get so sleep with the remaining time I have left, but I doubt I'll be great in the sunny morning, probably going to have to drink some espresso even before breakfast, or brunch.
