The “winter dreams” of the story refer to the American Dream that Dexter<span> comes to embody, but success brings a high cost, and social mobility restricts Dexter’s capacity for happiness. Dexter is from humble origins: his mother was an immigrant who constantly struggled with the language of her adopted homeland. The central irony of the story is that realizing the American Dream yields bleak rewards. For example, when Dexter was a young caddy, he dreamed about success and wealth and the happiness they would bring. When he finally beats T. A.
