Dreaming

From the day I looked up into the sky I saw A  entire universe of lights which determined my destination in life and defined the meaning of dream to me. The feeling was so intense that it rushed through my entire body. My brain was unable to process what I had seen, I couldn't think but i felt alive. I had seen the most magic thing possible :the stars. Behind those stars lyed planets and suns and rocks and most likely countless earth like planets. The one moment made me see my past present and future.  Made me realize that life is so vast and huge. Ever since then I have wanted to go above and beyond. The rush and energy I felt I feel every time i look up on a clear night and see the twinkling stars and planets so far far away.  My dream has always been to be among those stars and planets and have a change to go into space and look out and beyond into the universe. People may think some dreams never come true. But if you go to bed at night and all you dream about is your dream then how can that not become reality. Can a dream become reality?   Is it unrealistic to dream so big.
