I agree with curious...I've had my best lucid dreams during naps....Here's a funny example. I was having new floors put in, and the guys came at like 7:30 on my day off, so I was like I'm going back upstairs closeing the door and going back to sleep....well aside from the noise I was able to have one of my first reality check induced lucid dreams, but like usual I could'nt figure out what to do with my new found freedom....I was gonna strip down and streak infront of the workers, but I chickened out cause the dream felt too real
