Body clock - a myth or truth?

I have often heard people talk about ‘body clock’ wherein they mean that come what may, their body automatically becomes aware of the time and acts accordingly. Such persons do not need an alarm clock to wake them up every morning before going to work. It is also true that such people cannot sleep for a longer time even if they want to. I was simply wondering why it doesn’t become applicable to me. If I do not have my mobile phone next to me, I am sure to sleep for a longer time missing the alarms. On weekends, my morning begins when it is noon for the others.

I began contemplating on this for some time. Why is it that even if I get up at 5.15 every morning (except weekends) my body still needs an alarm to wake up? Why my body has a different time frame? I have discussed this with many people. Nobody gave me a clear answer. But I noticed one thing. When I have an ardent necessity to wake up the next morning to accomplish an important task, knowingly or unknowingly, I feed my mind with that thought until I shut my eyes. On such times, I become conscious very soon. It so happened that one morning, I dozed off because of a bad back without keeping any alarm to wake up. My sub-conscious mind began working and would have reminded my body about the pending work to be done at home before kids come back from school and that I should be awake at least an hour before they come. And guess what? I even dreamt about my kids waiting at the door while I am still asleep with no job done at home. I got up with a great shock within few minutes of my sleep and checked the time. There was plenty of time left for me. But that was a reminder fed in my sub conscious mind which worked! Though I do not have the guts to fully rely on my sub-conscious mind, I wish to try it out someday. This reminder of my mind works only when I have an urgent and inevitable job to be done. Otherwise, it also sleeps along with me  Why is it that only for me such feeding of data should be done as I sleep whereas for others, no such feeding becomes necessary? I have seen many sleeping without any alarms in their hand. I am really envious of such people. I wish I could change the battery of my body clock so that it begins to function like others’.

My brother-in-law once told me that body clock does exist in everybody’s body. He said that it has something to do with our mind. He told me that just before sleeping, I should imagine a clock (either analog or digital) indicating the time I wish to get up and then sleep and I am sure to get up the next morning at the same time. As I told previously, I never had the guts to risk leaving my mobile behind and once my mobile is with me, I cannot try any other methods. My sleep becomes blissful transferring all responsibility on my mobile phone. Thanks mobile phones for this most wonderful feature!
