Yea, a little sleep deprivation seems to work for me, just by looking at my dream journals. There is something called the REM rebound effect, (or something like that). Basically after a few days of lack of dreaming, it comes back in full force as though it is trying to make up for it.
Just this morning, I finally got a good night's sleep after a few days of restlessness, and had a very good lucid dream this morning. I woke up in the night and my mind was a little muddled and was thinking many random thoughts so I got up for a bit and went back to bed. My mind was clear, so clear in fact I wondered if I would ever fall asleep again. But my mind was clear and I think that is the main purpose of 'wake back to bed'.
Then I became lucid in a dream, but it was only at the end and I was upset and decided to just lay perfectly still after it was over and try to sleep again. I must have been in a very relaxed state, because I started to feel the muffled, buzzing sound in my ears and I just remained as calm as possible and it led to a very good W.I.L.D.
So what worked for me, was remaining perfectly still, and relaxed, DIRECTLY AFTER a dream. (Of course it helps that I was lucid at the tail end of the previous one...)
I have never had a W.I.L.D. at the onset of a night's sleep, only during the REM phase and only if I only BARELY wake up and remain fully relaxed. Tends to work for me at least, whenever it actually does happen.
If we all lucid dreamed this world would be a better place.
