Is it normal that i feel like i am shaking internally?
It started when I was trying to fall asleep one night and then all of a sudden, I felt like there was an earthquake. I look around to see if the nightstand or desk was shaking but they weren't. I then realized that the shaking was coming from inside me. I don't know how to explain it, but I am not visibly shaking externally. It feels like there's an "earthquake feeling" in my body. I checked my pulse to see if my heart was doing this but my pulse was a normal beat. I am 17 year old girl by the way and this only happens at night when I'm about to sleep. It happens about twice a week or so but I have no idea why this happens. I have no medical conditions and am not on any medication.
