ABOUT LIFE AND DREAMS

Checking my stuffs and books, I found this little phrase about Shakespeare :
“We are such stuff
As dreams are made on, and our little life
Is rounded with a sleep…”
…and I was thinking about the connection about life and dreams. Sometimes I had the doubt when I dream and when I am living this time of my life..All the things that I am living in this moment are dreams or my dreams (when I sleep) are part of my real life?
What’s the significance of life? Who are we?
Is human life just a dream, from which we never really awake, as some great thinkers claim? Are we submerged by our feelings, by our loves and hates, by our ideas of good, bad, beautiful, awful? Are we incapable of knowing beyond those ideas and feelings?
These questions are always invading my mind. This is the reason that I am alive. When I can make questions to myself, then, I am really alive.
Joseph Conrad said: “A man that is born falls into a dream like a man who falls into the sea”.
Is the reality we know a reality imposed to us by nature? Is the reality and the meaning of life a creation of men, such as music, or love or colors (science tells us that there isn't such things as music, harmony or colors in the physic world. Just traveling molecules: «There is not, external to us, hot or cold, but only different velocities of molecules; there aren’t sounds, callings, harmonies, but just variations in the pressure of the air; there aren’t colours, or light, just electro-magnetic waves», said H. Von Foerster.).

Are we - and all living beings - just «survival machines, blindly programmed to preserve the selfish molecules known as genes», as Richard Dawkins states? Are we incapable of knowing beyond the frames imposed to us by nature?

Is there any significance for life in a Universe of billions of stars that ignore us? Is there any significance for life in an Universe whose dimensions and nature overcome our understanding?
The most amazing certain in my life is my confrontation between my doubts and my faith. When questions invade my mind, I can see the light in the end of the tunnel, it is my faith. I believe I am a son of God and I believe that I exist in this life because God has a special propose for me. This is the motor that makes me alive and hope about my existence.
