The theme of the poem is death and the inevitability of it.
The author is trying to make themselves one with nature and its ugly surroundings that will over power him.
Explanation:
The topic and the theme of the poem 'Night walk' is the mortality of humans and their ultimate ability to not overcome nature.
The nature is shown to be burlesque in here and in horror is shown with imagery.
The images are haunting and betray the fact that the earth will claim the person back and they will die in the 'night' of their life.
The author expresses this pathos by the use of the imagery that is Gothic and produces the emotions of life energy and to affirm life against its purge.
