Freud indicated that when a person dreams he is dreaming, the inner dream contains the forbidden unconscious wish in a relatively undisguised manner. In Pirandello's drama, which is a play within a play and has a dreamlike quality, the principal theme is father-daughter incest. In discussions with his biographers, the playwright showed considerable resistance to admitting any connection between his unconscious and the subject matter of the play. The same theme occurs frequently in some of his other plays. The author presents biographical data to support father-daughter love as an important element in the emotional life of Pirandello.
