Do we take life too seriously?

What would you think if at the end of your life, you realised that it was just a dream or a movie of your mind ?

I believe that our soul is immortal and that there is a Creator that is in all of us. I believe that everyone and everything is connected in this world. I believe that reality is not that real and it's just an experience of our soul. It is hard to explain but I believe that if people new that their life is just a movie or dream and that one day they will simply wake up. Then they would probably live it differently. We live our lives in fear and anger just because we can't understand this simple fact. We take life too seriously. As a result we do wrong choices and then life in stead of beautiful experience turns into a torture. Many philosophers believe that we come to Earth to suffer. They say that if we accept this as a fact then our sufferings won't influence our mood that much. It's not easy to accept everything that life unfolds along the way but it is possible to always remember that everything is just temporary. We have to make choices that makes our soul feel in peace.
