I think Trevor has a point here, Whenever I oversleep, I usually don't even remember my dreams as well, this may not happen to everyone though. Also, if LD'ing were very well known, most people would try it, succeed maybe once or a few times and then just stop trying or lose interest because either they are not able to do anything worthwhile in their lucid dreams, there not able to control, or their waking life may just be too busy. The people who are naturally good a LD'ing won't need to sleep for very long periods of times to have long/frequent lucid dreams so they would not do that. So overall, I don't really think lucid dreaming has the capacity to become that addicting that it sucks you out of your waking life, but I do often wish that I could spend a lifetime stuck in a lucid dream. Sounds like one fun life!
