I have never experienced this before, mostly because I haven't tried it yet. One night, my alarm didn't go off. The next night I tried I woke up with a MASSIVE headache. Its just like anything you're scared of. I used to be scared of sleeping with the lights off in my bathroom. I just took little steps. Eventually, I couldn't sleep because it was too bright so I closed the door about halfway. Eventually, I just closed it all the way, but kept the bathroom light on. Next, I thought "well if I sleep with the door closed then I could turn the light off." I guess what I am saying is that just take it in steps. Just go further and further each time, and remember nothing can hurt you in SP.
