In Tennessee Williams's A Streetcar Named Desire, Blanche DuBois suffers from delusions of her attractiveness and beauty. Having married a young man who was tragically unable to sustain the marriage and, therefore, killed himself, Blanche finds herself attracted to young men in her tortured efforts to regain her youth and the youthful lover she once had. This desire to reclaim the young man is part of her personal belle reve. But, this dream is just like the plantation, Belle Reve: lost.
As she waits for Mitch to come to the apartment, a young salesman knocks on the door. Again, Blanche is caught between reality and her delusions and she flirts with the young man. This behavior is in sharp contrast to what she has said to Mitch about keeping her reputation. Indeed, Blanche's trysts with the young men are the unraveling of the illusions of Blanche's "white" facade and her real nature.
