In Dreams Begin Responsibilities
Schwartz wrote "In Dreams Begin Responsibilities" over a July weekend in 1935, when he was only twenty-one. A day later, his friend William Barrett appeared at the boarding house off Washington Square where Schwartz was living that summer and found the author ecstatic; he knew he had written a masterpiece, a verdict later confirmed by Vladimir Nabokov, who singled [the story] out as one of his "half a dozen favorites" in contemporary American literature.
The story was first published in 1937 in the first issue of Partisan Review. A year later it was published in Schwartz's first book of poems and stories which was also entitled In Dreams Begin Responsibilities. The title came from the Irish poet W. B. Yeats' 1914 volume of poems Responsibilities, which has an epigraph "In dreams begins responsibility," attributed to an "Old play."
"In Dreams Begin Responsibilities" is widely regarded as one of Schwartz's finest stories and is frequently anthologized. Of all of Schwartz's stories, it is probably his most well-known and influential.
The story is currently available in print in two posthumously published collections of Schwartz's work, In Dreams Begin Responsibilities and Other Stories (1978) and Screeno: Stories and Poems (2004). In a 2003 review of In Dreams Begin Responsibilities and Other Stories that appeared in The Observer, Jason Cowley wrote, "[Schwartz] never wrote a finer story than 'Dreams'." 
The story tells of an unnamed young man who has a dream that he is in an old-fashioned movie theater in 1909. As he sits down to watch the film, he starts to realize that it is a motion picture documenting his parents' courtship. The black-and-white silent film is of very poor quality, and the camera is shaky, but nonetheless he is engrossed. Soon the young man starts to get upset. He yells things at the screen, trying to influence the outcome of his parents' courtship and the other people in the audience begin to think he is crazy. Several times the character breaks down. In the end he shouts at his parents when it appears they are going to break up, and he is dragged out of the theater by an usher who reprimands him. The animated version is important to the story, as it reveals a bit of the character's insecurity. In the end, the character wakes up from his dream and notes that it is the snowy morning of his twenty-first birthday.
