What are some poems about dreams?

I'm doing a project where I need to pick 3-6 poems of a certain topic or motif (theme). I picked dreams as my theme and i need poems about dreams. They need to be by "recognized" poets (I.E Shakespeare, Whitman, Yeats, Poe, Hughes etc...) I have found some already basically the ones that have the word Dream in the title I have already found. SO what I'm asking for is any really good poems by really well known poets about dreams that I probably don't know.
