My night-fancies have long ceased to be afflictive.  I confess an occasional night-mare; but I do not, as in early youth, keep a stud of them.  Fiendish faces, with the extinguished taper, will come and look at me; but I know them for mockeries, even while I cannot elude their presence, and I fight and grapple with them.  For the credit of my imagination, I am almost ashamed to say how tame and prosaic my dreams are grown.  They are never romantic, seldom even rural.  They are of architecture and of buildings—­cities abroad, which I have never seen, and hardly have hope to see.  I have traversed, for the seeming length of a natural day, Rome, Amsterdam, Paris, Lisbon—­their churches, palaces, squares, market-places, shops, suburbs, ruins, with an inexpressible sense of delight—­a map-like distinctness of trace—­and a day-light vividness of vision, that was all but being awake.—­I have formerly travelled among the Westmoreland fells—­my highest Alps,—­but they are objects too mighty for the grasp of my dreaming recognition; and I have again and again awoke with ineffectual struggles of the inner eye, to make out a shape in any way whatever, of Helvellyn.  Methought I was in that country, but the mountains were gone.  The poverty of my dreams mortifies me.  There is Coleridge, at his will can conjure up icy domes, and pleasure-houses for Kubla Khan, and Abyssinian maids, and songs of Abara, and caverns,

  Where Alph, the sacred river, runs,

to solace his night solitudes—­when I cannot muster a fiddle.  Barry Cornwall has his tritons and his nereids gamboling before him in nocturnal visions, and proclaiming sons born to Neptune—­when my stretch of imaginative activity can hardly, in the night season, raise up the ghost of a fish-wife.  To set my failures in somewhat a mortifying light—­it was after reading the noble Dream of this poet, that my fancy ran strong upon these marine spectra; and the poor plastic power, such as it is, within me set to work, to humour my folly in a sort of dream that very night.  Methought I was upon the ocean billows at some sea nuptials, riding and mounted high, with the customary train sounding their conchs before me, (I myself, you may be sure, the leading god,) and jollily we went careering over the main, till just where Ino Leucothea should have greeted me (I think it was Ino) with a white embrace, the billows gradually subsiding, fell from a sea-roughness to a sea-calm, and thence to a river-motion, and that river (as happens in the familiarization of dreams) was no other than the gentle Thames, which landed me, in the wafture of a placid wave or two, alone, safe and inglorious, somewhere at the foot of Lambeth palace.

The degree of the soul’s creativeness in sleep might furnish no whimsical criterion of the quantum of poetical faculty resident in the same soul waking.  An old gentleman, a friend of mine, and a humorist, used to carry this notion so far, that when he saw any stripling of his acquaintance ambitious of becoming a poet, his first question would be,—­“Young man, what sort of dreams have you?” I have so much faith in my old friend’s theory, that when I feel that idle vein returning upon me, I presently subside into my proper element of prose, remembering those eluding nereids, and that inauspicious inland landing.
