Caughting the light

I went to a great length to have a good night sleep. But it just won't turn the way I wanted it to be. Then I'll be up until 2 am or 3 am. Its hurting my eyes and my brain.
I looked out from my window. There I see a beautiful dawn. I flipped my eyes for some time.
Its getting brighter and brighter each time I try to close my eyes. It was so dark when I just lying there. Where the hell did the light comes from??

thats all..
