This story is called "Hepzibah's Dream".
But they changed the title when they reprinted it. Since the copy of this story with the alternate title is much clearer we'll use that, even though it doesn't have the name Hepzibah on it.
And here we have the cover of the comic book where this story was originally published. It has the original title on the cover, too.
