How can sleeping during the day effect your ability to become lucid? I've been on third shift for the past two years now and it seems that lucidity just becomes harder and harder to obtain. I feel my main issue is that my sleep schedule is not regular, I never go to sleep (or wake up) at the same time. What can I do to get on a regular sleep schedule? Also, I sleep with a very loud fan to drown out any 'daytime' noises, could this also effect anything with LDs, dream recall, etc.?
