There have now been 4 times when I’m up sort of late and trying to fall asleep, I randomly either fall asleep and then shortly after wake up with a mild shake or I don’t even feel like I even went to sleep and then open my eyes and feel the shake. I feel like someone is shaking the bed but when I sit up, no one is doing it and my hands are shaking very very gently. This lasts for less than a minute and than it’s back to normal. Is this anxiety related? I don’t feel afraid when I wake up but it’s still a scary thing to experience. I keep seeing forums mention anxiety but I just don’t know..
