I kind of know what you mean. I had an intense lucid dream lasting what seemed like about an hour dream time, maybe about 25mins normal time about 2ish this morning after drifting off unexpectedly before the bed time rituals that usually set you up for a deeper sleep. I won't bore you with the details but flying around above a huge indoor pool for a lot of it!

Anyhoo, I don't usually get these things all night long, but I was woken a fair few times by how cool flying is last night. I always fly. It has to be done. Luckily no work this week so I could lay in but unbelievably tired this morning and not very well rested. Its probably because I haven't yet mastered keeping that state steady for longer periods of time although the spinning around thing works pretty nicely most of the time. But It wasn't like I was woken up all the way through the night, only a few times.

Does lucidity prevent you getting to the restorative stages of REM? You get them popping up at all times of the night, but maybe only when you're faily shallow or hypnogogic? Bad spelling? If you maintain that state which I'm getting better at gradually, does that mean you're depriving yourself of the deeper stages where daily memory consolidation takes place? Too much fun could be a bad thing...
