images lost

There was a time when I closed my eyes and I could see incredible worlds exploding with colors, vibrant and full of life. I am not sure how many years ago, must have been eleven or twelve; I would close my eyes and the only image i would see was an old oak tree. It was like an old black and white image, that slowly began to dull and fade. then it was gone and there is only darkness, a black inkiness that stretches on forever with out end.There are times when I long not for the colorful worlds, but just for another glimpse of that tree off in the distance. I want to remember how it looked. I keep telling myself that if I could see it again, then whatever it is that died in my mind was coming back to life. That maybe my memories, the few that I can seem to hold onto, will become more than just words going through my mind like pages out of a book, or sounds from a radio and there will be actual images with them. Something, anything to break through the darkness behind my eyes.
