That happens to me about 3 - 4 times a week. As I'm waking up it feels impossible to move for like ten minutes. I almost start to panic as I'm breathing hard. But, then I come out of it and get angry. Then I realize it happened again and get frustrated. Then I watch TV to try to get my mind thinking about something else.Have you ever felt like something was forcefully holding you down as you were sleeping? That happened to me last night!
