i average about 5-6 hours per night. 8 hours seems like an eternity, i rarely sleep that long, it freaks me out to get that much sleep.
i often have really weird dreams, lots of action dreams which are often cool, sometimes get into chronic nightmares though.....
when i'm training alot, especially when getting ready for a tournament, i punch and kick in my sleep and thrash around alot, i guess i'm dreaming about training and fighting then. it drives my girlfriend crazy, sometimes i hit her in my sleep and she wakes up and yells at me
