What is real and what is not? What if the life we think we live in is all but a dream? What if the dream we think we dream of when we sleep is the true life we are living, except that we do not remember most of it? 

 Perhaps lifeforms are all but non-existent in this world that we know of. Perhaps we are all part of a virtual game. Our actions and thinking are comes not from us but an external partner. The player who plays out us that is. Perhaps life is nothing more than just a game on a virtual platform. Perhaps the reason why we need to sleep everyday is just so that our mastermind could pause the game and log out of our lives just for a few moments. Perhaps that's the reason why we are all alive but do not know the reason behind our existence -- because our lives is just a game of someone else.
