Edgar Allan Poe

"For my own part, I have never had a thought which I could not set down in words, with even more distinctness than that which I conceived it. There is however a class of fancies, of exquisite delicacy, which are not thoughts, and to which as yet I have found it impossible to adapt to language. These fancies arise in the soul, alas how rarely, only in epochs of intense tranquillity, when the bodily and mental health are in perfection, and at those mere points of time, when the confines of the waking world blend with the world of dreams. And so I captured this fancy, where all that we see or seem, is but a dream, within a dream."
