In the poem "Desert Spaces" by Robert Frost talks of emptiness, loneliness, and uses winter's snowfall to describe the feelings and emotions brought on by winter. 

Line 13 speaks of man's own fears and the way in which man causes himself to feel afraid by loneliness.  Mankind has a needed for the involvement of other and a person looking over a blank white space such as the snowfall witnesses’ isolation.  Frost is also referring to his own self and thoughts.  The term “they” are Frost’s own thoughts which at present seem to be dormant and useless with the exception of serving to make him feel more isolated.

In line 16 of the poem Frost uses desert places to describe the desolation and loneliness that he feels.  Winter is often a time of seasonal depression and the theme of this poem demonstrates those feelings.
