From what I've read about attaining lucidity, it helps if you're relaxed, meditated and comfortable. Have you ever had a nice warm bath with bubbles and candles, and fallen asleep? If so, did you have a LD? Was it vivid? How lucid were you?
I'm going to try it tomorrow night sometime and see, I will post results.
What do you think of this? Is it a good idea to fall asleep in the bath?
