FEELING SLEEPY....?

Sleep. One of the most relieving act. We sleep to vanish our tiredness. We sleep to vanish our anxiety and tension. But do we really sleep ? A very dear person to me sleeps all the time. yes , all the time. For that person sleeping is a kind of entertainment. Another very dear person to me does not sleeps not even in the night time. For me, both of them are suffering from sleep disorder. If one is sleeping all the time, obviously the normal sleep time for that person is not enough. Is'nt it a sleep disorder then ?
Why are most of us suffering from sleep disorder ( yes, psychoanalysts says 90% of us ) ?. The reason is simple. We sleep while we are awake. Yes, we do all the things unconsciously. For an instance, we drive from home to office and we keep on thinking other things and we reach our office. We don't even concentrate what we are doing in present. Our mind is working in past and future thinking only. This kind of working of mind makes us unconscious. And unconscious working means sleep. And one who sleeps while being awake cannot sleep in night. Most of us function in this way.
So, my advice to those who are suffering from sleep disorder should try to improve their consciousness instead of trying tranquilizers.
