Nonsense of an ending - ways to rewrite one short story

I've admired a lot of Stephen Millhauser's stories over the years esp w recent encouragement from friend WS finding them almost always mysterious and peculiar and therefor provocative and story in current New Yorker, Coming Soon, meets these criteria up to a point. Story is about a 42 year dol man named simply Levinson - like many Jewish male protagonists he goes by surname only - why is that? I very done this in my own writing - who has relocated from NYC to a small upstate community seemingly much like Saratoga springs where sm works. He notices to his surprise that the community is thriving and very pleasant and even edgy much like Brooklyn but without the crowds cost and pretension. He also notes that the city is growing all the time - a sign Of its prosperity - new houses remodeling new ethnic restaurants boutiques and so forth. L drives around noticing and admiring these changes , which SM lovingly conveys in detail.  But then - all goes to sleep or suffers a gap in time (echo of another upstate sleeper?) and wakes to find he's lost he doesn't recognize his own street. And then he drives away. This then is a perfect ex of a story w a wonderful premise and setup but w no ultimate point. sM doesn't seem to know what to do w this material. What would he advise one of his students? Perhaps work it further - make L an present day rip vw when he wakes? Or build this into some kind of metaphor for life's journey toward death? Or have L learn and grow thru the course of the story perhaps at outset he could be contemptuous or condescending toward those who resist change and at the end that's him or make the city grow into something horrid? Many possibilities - but I found the end just left me disappointed and flat.
