What is dream?
Google says “a series of thoughts, images, and sensations occurring in a person’s mind during sleep”. Leave Google aside, what you will say if you are asked for the same question in F2F interview or in school auditorium or when you are at the do or die situation.

Answer for “what dream is” is sleeping inside within it. From our school days, all the teachers asked us to read the question twice or till understood. Have we all done that?
Too confused… or you started thinking too much. Good, within few minutes you get answer on our own “what the dream is?”
What is nightmare?
Now, we will move to the question of nightmare. You want to ask Google – do it. But you wouldn’t get definition or you won’t understand it. Defining something is easy than experiencing. One Tamil poet stated that “explaining as same as what already defined is science — in other case, explaining what we understood is art”.

Here-from, anybody will finalize the Google statement. Now, all come to your last position that is where you stand in the auditorium, how you sat in the F2F interview, and angled your head to the last position of the pistols.
If you get answer now, then it’s nightmare. Your failure may be the dream of your competitor and vice versa.
Now formulate the definition of dream and nightmare according to your own understanding. Up to me:
DREAM: as you wished it to be.
NIGHTMARE: as you expect that particular thing should not happen.
What happens when we get a nightmare?
Nightmare is all about extreme positivity or budding of negativity. For instance, assume that you are in golden 80’s and 90’s. During those days, middle aged scorching sunlight fills your large street surrounded by trees on two sides; you are watching cricket finals between India and Pakistan in television with your friends, now it is time for spinning the toss. When the coin span in the air, suddenly there was power cut in your residential area.
Electric power in your whole town was not being provided for very long time. So that, you started nap amid your friends sound about cricket match, power issue, etc.,
In your half sleep, if you get have running video where the toss own by India and first ball shot to the six by Sachin – it’s your dream. If the same video, shot hit by Sachin caught by the fielder in the boundary line – it’s your nightmare even if you are have it in day time.
Dream vs Nightmare – which one is true?
Yesterday dream is today nightmare. If you get sleep in free of cost, without using tablets, then you are lucky enough. As in this generation, getting sleep is itself big dream for many people.
What are going to do with that indication — may you start worry soon. Why we should think about the dream/nightmare every morning. You know why? Think about this today in your bed if you are suffer without proper sleep.
