Distractions and me

Life can be boring sometimes. I get bothered too often when I am distracted by something, especially when I am doing something or reading something with so much deep concentration. It is like the feeling when you are in too deep into your sleep and someone shake you and wake you up. Don't know is that normal to be annoyed. Sound is one of my greatest enemies. I have seen so many people can work when there is a lot of sounds around but I can easily lose my focus even in very small sound. I sometimes think if it would be possible to have the complete calmness in the brain and to do stuff joyfully without any distraction.
