Lucid dreaming (generally) occurs in REM, I've heard that some people are able to extend their lucid dreams and thus their REM.
My question is (for those who have a Zeo or similar), for how long can you extend a lucid dream and how rested you feel afterwards?
Thanks :)
P.S: Yes, this is inspired by dreamviews "staying up all night" slogan, yes, I aspire to that, if possible :D
