I can fall asleep at anytime of the day and sometimes  I can't even resist. Last week alone, I fell asleep at least 5 times in class. It's not even sleeping really, it feels like being barely awake and dreaming at the same time, so the real world and the dreams get mixed up. I don't feel OK. What's even more weird is that when this happens, the process feels like hours, but when it's over I see that it only took about 5-10 minutes. I'm not sure what this could be and I don't feel comfortable talking about this to anyone. Any ideas on what this could be ?
