I think, therefore I am.

Thinking about something is like picking up a stone when taking a walk, either for skipping rocks on the beach or looking for a way to shatter the glass doors of a museum. When you think about something, it adds a bit of weight to your walk, and as you think about more and more things you are liable to feel heavier and heavier, until you are so burdened you cannot take any further steps, and can only sit and stare at the gentle movements of the ocean waves or security guards, thinking too hard bout too many things to do anything else. 
 ― Lemony Snicket, The End  
 

  There's no special time-frame or a slot in your time table when you sit down and think. Its like a   biological, not everyone thinks,  natural process that goes on in background all the time. I do it all the time... knowingly or unknowingly the process is on. Even between the time when I'm half awake and half asleep just when I'm almost sure that day is off and the veiled Peter Pan in me can escape in my perfect Neverland. A thought, out of nowhere, closes the doors of my dreamy land away and leaves me digressing in the boondocks of my unceasing thoughts. 

I almost slept 
may be seen a dream or two
and then it happened
Out of nowhere
that midget thought
unloaded in my head.

It was already booming
with the debris 
I collected that day
No more, my stack's 
full I pray. 
Then I start talking
to no one, but Me. 
Too ergodic 
all that clutter
makes no sense. 
to Me. 

Then I cling on to one
out that mesh of mess
I pick one.. 
about the days gone by 
or time yet to come.
Basked in those 
misty thoughts
my sleep is long gone 
twisting and curling 
on my bed
euphony is on. 

I can think so much
may be it never ends 
when this night ends 
there's another at hand. 
I sleep with one 
and I wake with one
with everything on
it goes on and on. 

I dread of the day 
if it ever stopped 
I'll be awake
for forever, glancing 
wild blue yonder
or will I sleep it all ?
