Somehow my unconcious self has complete control over when I get out of bed. No matter what I do I end up sleeping until 9pm everytime my girlfriend doesn't come over. Because no one is around to wake me up. I can set my sights on getting up at anytime and be dead serious about doing it, but no matter what, in my sleep, I turn the alarm off before it rings.
Even when there's a person laying in front of me, in my sleep I will tell that person (clear as day, not one hint of sleepiness in my voice, I'm told) to turn it off.
I set my alrm for 5:30 and I put a few bottles in front of it, as well as a bank filled with coins. A trap. I thought "If I knock this over in my sleep I'll wake for sure, and my body won't know enough not to knock it over." Yes, I was wrong. When I woke up and turned the light on I found that the bottles and the coin jar were laying on a crumpled blanket that I must have thrown on the floor in my sleep. I suspect my unconciouss self of doing this on purpose, knowing full well about the trap I had laid for it and how to get by it without my conciouss self taking over. I've also had experiences upon waking where my clock was set back a few hours so I would sleep longer.
