I know exactly what you mean about that evil feeling. Waking yourself up is not a good way to deal with it, though. If you are lucid, then it is important to tell yourself that nothing can hurt you in a dream. You have to stand up to the fear before it will go away, no matter how overpowering it is. Every single time that I have done this, the evil feeling was replaced by something that was so ridiculous that it was almost laughable.
