Snooze Button

I love the snooze button, perhaps too much. On most days I don't HAVE to get up when the alarm goes off. I'd like to get up, to get some stuff done, but I don't HAVE to get up. So, I wind up pressing snooze...and pressing snooze...and pressing snooze. I wind up staying in bed for an hour, sometimes closer to 2 hours, from when I set the alarm. Why don't I just set it for later and get better sleep all the way through? I'd still be wanting to press snooze and thus sleep even later! The interesting thing is that I sometimes still dream in those 9 minute intervals. How does that work? I thought you had to sleep like 20 minutes to get into REM sleep. Hmmm. Interesting.
