to create the imagery of helplessness while pinned down like a bug in a board or wall.
Explanation:
In the poem "The Love Song of J. Alfred Prufrock" the author says that 'Prufrock imagines people's eyes stabbing through his body and impaling him to the wall where he wriggles as people examine him' to create the imagery of helplessness while pinned down like a bug in a board or wall so that people can stare at it and examine it.
This imagery produces a similar picture to bug-collection where bugs are pinned down to a board so that people can view them. As the poem talks about the narrator's struggle with indecisions, the imagery helps us understand more about why the narrator is preoccupied with anxiety.
It is because he feels like he is pinned down on a board and people are waiting for him to make a decision. This makes him more nervous and anxious which ultimately makes him indecisive.
