Impression of a Dream

My first impression of the poem is that it tells a lot in it. It talks about whether reality is a dream or the dream is the reality. I think that when you dream of something that has occurred in your day its just your brain telling you your own perspective on the topic. Or what you are really thinking about that person or topic. Like when you watch a scary movie you might have a nightmare about it because you found it to be something that you are really scared of.
