Secondary World: The Imagination

Pictures flash through my mind of a life I have never lived. All the things I've hoped for, feared, and loved appear before me. I accomplish goals and live life; a new and different life from my own. Whose it is, I do not know. It isn't until my feet hit the cold floor, that reality finally hits me, like a car crash in front of my face, just barely missing me. It's then I realize that my imagination has, once again, taken me for a wild ride. Every night I live a life, one secondary to the one I have now. It is so real and vivid; how is it only my imagination?
