All said and done it is an enigma why we have to sleep in the first place. The answer given in my literature says: sleep is a must for the human body for it has to carry out its internal repairs like cleaning, getting rid of the dead cells, rejuvenating systems etc. I find some sleep with pillows stacked high under their heads or backs while some do without. My literature advised I should roll a thin towel into a convenient lump and place the same under my neck. For that matter, while asleep, I roll on my bed making different postures like in Dasavatarams. I got a helpful hint that doing so helps one not get bed sores (not bad). These days I lie on to my left side while sleeping that would do a world of good to my gas as my literature says as my stomach empties contents faster into my duodenum in small intestines in line with the gravitational pull (Must be a genius who wrote this tip, next to Newton). 

In my experience, the daily siesta (the afternoon nap) works wonders to keep our mind refreshed. A catnap in the office won’t hurt and it is the answer. I see some high tech offices allowed their sleep-hungry staff to officially snooze to increase the general health of company. In other ‘normal’ offices, no wonder certain folks  improvise sleeping with eyes wide open and staring blankly at the monitors or notebooks as if reading from them without registering the details. Same thing goes in meetings where except the speaker the rest are sleep arrested. On a sad note we note accidents involving motor vehicles, trains and even flights when drivers concerned (unconcerned) suffered mainly from sleep problems. In that state they are prone to get momentary lapsed into unconsciousness loosing controls at the dashboard. (I pity the average engine driver in railway trains tagged by many sleepers coaches containing sleeper passengers and himself running on stony or wooden hard sleepers misses his sleep).  

The last chapter in sleep literature with me says we dream during a cycle called Rapid Eye Moment stage. As a child I used to wonder do we really dream in colors or just in the old Black and White movie version. Now it seems to be a settled matter that we see events in our dreams in multicolor (maybe that is after color TV came into the picture). Another interesting tidbit is that we get dreams mostly in early morning (most are sweet in my case). It was also mentioned we dream only during REM stage of sleep in each of 5 rounds but only could remember (vividly or vaguely) the dreams occurred during last REM, that happens when we were about to wake up. Those who had a peg or two too many, may wake up to some confusion as their gaunt and ghastly faces stare back from the bathroom mirrors. It is thanks to the lack of normal sleep cycles in their drunken dozing. 

Finally, what one needs therefore is some quality sleep on a light stomach maybe after some warm drink that has no caffeine or other stimulant, and optionally with moving lips that say just a prayer.
