A thought went up my mind to-day <br />That I have had before, <br />But did not finish,--some way back, <br />I could not fix the year, <br /> <br />Nor where it went, nor why it came <br />The second time to me, <br />Nor definitely what it was, <br />Have I the art to say. <br /> <br />But somewhere in my soul, I know <br />I've met the thing before; <br />It just reminded me--'t was all-- <br />And came my way no more.<br /><br />Emily Dickinson<br /><br />http://www.poemhunter.com/poem/a-thought-went-up-my-mind-to-day/
