Describe symbolism in A Rebirth by Faroogh Farrokhzaad

One important theme in this poem is that of depressed emotions. Loneliness and sadness permeate the text, as do negative images. For example, the speaker opens the poem by referring to herself as a "dark sign," a symbol or warning of something depressing about to happen. Those who gather around her, she warns, will be affected by her depression.
