Also he had seen an incubus once, and several times he had seen the great bat that sucks the blood from the necks of people while they are asleep, fanning them softly with its wings and so keeping them drowsy till they die.
He encouraged us not to fear supernatural things, such as ghosts, and said they did no harm, but only wandered about because they were lonely and distressed and wanted kindly notice and compassion; and in time we learned not to be afraid, and even went down with him in the night to the haunted chamber in the dungeons of the castle.

The ghost appeared only once, and it went by very dim to the sight and floated noiseless through the air, and then disappeared; and we scarcely trembled, he had taught us so well.

He said it came up sometimes in the night and woke him by passing its clammy hand over his face, but it did him no hurt; it only wanted sympathy and notice.

They had no wings, and wore clothes, and talked and looked and acted just like any natural person, and you would never know them for angels except for the wonderful things they did which a mortal could not do, and the way they suddenly disappeared while you were talking with them, which was also a thing which no mortal could do.
