Dream within a dream

This poem is an example of Romanticism. It uses the words me which wasn't written in colonial liturature. Poe is normally a person who writes about dark matters, but in this literary work writes in a way that there was a good patch in his life. But since everything is dark to Poe, he finds it hard yo believe something good is actually happening to him. So by questioning it, he lost it and relized it was not a dream but reality.
