A just recently started doing something I find kind of scary in my sleep. It will usually happen when I am having a bad dream, and it's like i'll start to slowly wake up because I feel my lungs and chest burning and then i'll jerk awake realizing i've been holding my breath. My lungs and chest will burn so bad and i'll have to stay awake until it goes away. Do you think it's possible for me to one day suffocate myself in my sleep, or will I automatically wake up all the time? And why am I doing this?
