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 some one gently rapping, rapping at my chamber door.
"'Tis some visitor," I muttered, "tapping at my chamber door–
Only this and nothing more."

The speaker is napping and does not hear a visitor who taps on the door.
