Explanation:

The Scene the question refers to is from The Raven by Edgar Allan Poe:

Once upon a midnight dreary, while I pondered, weak and weary,

Over many a quaint and curious volume of forgotten lore-

While I nodded, nearly napping, suddenly there came a tapping,

As of someone gently rapping, rapping at my chamber door.

"'Tis some visitor," I muttered, "tapping at my chamber door-

Only this and nothing more."
