Dreams and Ghosts by Samuel Taylor Coleridge

There is a great difference in the credibility to be attached to stories of dreams and stories of ghosts. Dreams have nothing in them which are absurd and nonsensical; and, though most of the coincidences may be readily explained by the diseased system of the dreamer, and the great and surprising power of association, yet it is impossible to say whether an inner sense does not really exist in the mind, seldom developed, indeed, but which may have a power of presentiment. [1]

All the external senses have their correspondents in the mind; the eye can see an object before it is distinctly apprehended; -- why may there not be a corresponding power in the soul? The power of prophecy might have been merely a spiritual excitation of this dormant faculty. Hence you will observe that the Hebrew seers sometimes seem to have required music, as in the instance of Elisha before Jehoram: -- "But now bring me a minstrel. And it came to pass, when the minstrel played, that the hand of the Lord came upon him. " [2] Every thing in nature has a tendency to move in cycles; and it would be a miracle if, out of such myriads of cycles moving concurrently, some coincidences did not take place. No doubt, many such take place in the daytime; but then our senses drive out the remembrance of them, and render the impression hardly felt; but when we sleep, the mind acts without interruption. Terror and the heated imagination will, even in the daytime, create all sorts of features, shapes, and colours out of a simple object possessing none of them in reality.
