For context, I’m 19F. Sometime this month or last, I seemingly randomly had a bit of an anxiety attack as I was just entering REM sleep one night. It freaked me out because the main reason was for some odd reason my brain told me I was going to die if I didn’t wake up. I fully woke up and tried to shake the feeling and eventually I was able to go back to sleep. The other night, the same thing kept happening except this time every single time I was about to enter REM sleep I would get this jolt that would startle me awake, basically what I believe are hypnic jerks. I also tend to feel like I’m falling into my bed and it makes it hard to relax mentally enough to actually fall asleep. Now, I can only sleep during the day like I’m nocturnal and only about an hour or so at a time. I’m fairly sleepy but nowhere near how tired I usually am and I’m also used to sleeping an absurd amount. I have never had actual prolonged trouble falling asleep. I don’t feel very anxious but sleeping has become a difficult task. Wth is going on?
