ok, I am not going to really answer whatever your asking, but i can tell you what I do to attain lucidity. I do WILD, after 5 1/2 half hours of sleep I wake up, cut off the alarm clock, slap myself, but do not get up, and I am getting SP in like 2 minutes. The main thing I can tell you is if you get up in the night and can not go back to sleep, then wake up earlier into the night that way you will go back to sleep, say if you go to sleep at 10, wake at 3 and that should be sufficient, make sure you are tired when you do it, and do not fear SP, welcome it, just imagine a song in your head that you like while the SP is happening.
