Dreams unlimited

yesterday as it was 'International sleeping day' i was sleeping a lot as you saw in my blip. Then, i came to know i was dreaming a lot these days :-)
I feel we dream unconsciously and think consciously.Thinking is like calculations of known variables by a machine called brain.Results will never go out of bounds as variables are known and formulas are in there.
Dreaming....? God knows what it is? As I am not conscious while it's happening.

and these pictures i think it is a jet making rounds today, i see these a lot as there is one aero company near seattle.
