I've found it amazing, because I can sleep longer, and get more dreams, and not have to wake up to an alarm (which makes me forget my dreams a bit). It's been good for my dream journal. I've also not been true to my sleep schedule (well I still go to bed around and wake up at the same time everyday, just not the time I usually do when I have school) yet I still have a lot of dreams and even had a lucid dream around the time I expected. Don't do that, though, a regular sleep schedule is good!
