The poem describes the speaker's happiness upon listening to a dryad singing joyously in a forest grove. In the first stanza, the speaker feels as though they have drunk hemlock or opiates, and their senses are numb with drowsiness and pain, yet they find joy in the dryad's happiness. In the second stanza, the speaker wishes to drink wine that would allow them to fade away into the forest with the dryad, leaving the physical world behind.
