Great quote..
"Everyone in the world should get a standing ovation at least once in their life because we all overcometh the world.
-Auggie"
Suppose that you are on your death bed (don't take it otherwise) not exactly a death bed but on a road after being hit by some speeding car, then the car stops and a beautiful girl comes out of the car, worried (obviously), running towards you. But you are lying there tied to a mere thread of consciousness, saw her and immediately losses consciousness.
Then while you were unconscious you were dreaming, right from the starting i.e. that is your birth, you were a happy child (whatever your life story really is), went to a good school, got good grades, then college, you are popular in college, you met the same girl, who came out of that car after hitting you, you fell in love, immediately, she also liked you.
You both in love deeply, married together, had many cheerful experiences in life, in short it was the life worth living.
But since you were very happy something had to happen, you both had gone for a long drive and enjoying the moment, then a speeding car becomes the cause of your wifes death.
Then with a jolt you wake up in a hospital, beside you is the same girl, weeping for what she had done, and you are smiling, happy from inside that she's alive, that it was only a dream.
But really was that just a dream or your whole meaningful life in a dream?
That's how it is we can also be the same case as the one above who knows.
