What the heck just happened.
Sometimes when I try to sleep I hear a loud, long beeping sound in one ear and wake up. When I try to go back to sleep and I do I then wake up unable to move. Most times I have my eyes open and I am conscious and can't breathe well but can only move my arms and head. I feel like this until I shake my hands or head enough that I wake up. On certain times I feel like being strangled or having my whole body shaking. When I do wake up I dare not go to sleep again until it gets so late and I get so sleepy that I get to sleep without knowing. Is it normal?
