Symbolism adds depth and meaning to a poem, it can also make a theme and plain stories turn into a strong poem or paper. Another literary device used in Schizophrenia, is symbolism. There are many conventional symbols used as well as plain symbolism. The first conventional symbol is the word night, “Certain doors were locked at night” (5). Many people understand that night can be a symbol for depression, or being in a dark place. Jim Stevens wants the reader to understand how much of a dark place the family is in when he uses the word night. He also places the word “night” in a sentence about keeping others out, and people with schizophrenia are typically paranoid.
