Hmmm. Interesting problem. I once had the prospect of "working for" the devil. It was pretty scary. When I realized I was dreaming, I decided I would bitch slap the devil. I tried to get others attention to show them what I was about to do, and then I woke up, so I never got to do it, but the point is, I was going to, and this is the opposite of wanting to wake up from a lucid dream from fear not being able to wake up, or not being in control. I wish you luck.
