Dreaming minus Thinking

I would like to make one thing clear before I seriously start to write someting.Here,Im not talking about the nightmares or bad dreams that we come across when we are asleep but about those dreams which we feel good about. (You will understand it at the later part)
     "All human beings are also dream beings. Dreaming ties all mankind together"-Jack Kerouac.This is so true. Isn't it ?But what when we start thinking on our dreams.?Suppose , your dream is to buy a brand new car .You imagine about the latest technologies in it,color,its special characteristics,a long drive, family and friend's wishes etc..such a happy moment !! but,to make this happen , you have to buy ! If you have enough money , it's done but when when you realize that you are in short of it , then you begin to think ! Tragedy...This is just an example.Car can be replaced with any of your dream and money with anything which is a big reason that makes your dream unaffordable.Now, when you start thinking,things tend to take negative side .Time factor to accumulate money,cost price statistics,versions in the same model etc..What a difference in DREAMING and THINKING ! Does thinking bring a pause ,a jerk to our goals,ambitions,dreams ? ( considering goals and ambitions as dreams).Well,in this case it does.By subtracting "thinking" from "dreaming" , life seems so nice and enjoyable. Everything looks easy and smooth.I have no definition to the word dream and thanks to -------- (what ever you felt that brought this wonderfull experience to the world) !!
