Fifteenth - IDK

Well my nap was similar to many previous ones, i got some where between 10-22 muntes of sleep. At one time i think i woke up and kept thinking about how i needed to go back to sleep and how much i was missing out on my breif amount of sleep. This is a wierd event, but has hapened before. I usually then go straight back for what feels like 1 minute before the alarm goes off, but my sleep times have to be pretty far off becuase i never can tell how much i am actually asleep or not.
