Yup, it's actually natural for you to do this. For me however I've developed a horrible habit in my half sleep
I kill alarm clocks.
And I don't mean I just hit the snoze button for 6 hours. I stab them. With daggers, swords, etc. My girlfriend doesn't mind, because I've never stabbed her. but she got the bright Idea of putting it away from our bed.
That lasted 2 days. On the second day I got up, picked up a log splitting maul, and ass raped that poor clock. (*Insert, "So that's why your anti-clock?" jokes here)
When I wasn't living with my girlfriend I would often set 5+ alarm clocks in 15 minnute intervals. That didn't work either. My record so far is 20 alarm clocks. I killed about 12 of them before I finnaly "woke up"
I just need somebody who can get up, to wake me up. So my girlfriend wakes me up after she gets up from the one alarm clock that I sleep through. But recently my internal clock has just reset itself so I can get up on time.
I've been clock kill free for 2 months now. The last one got a swift blow from my Kukre. Suprisingly i've never gotten electrecuted while doing this.
