A selfportrait can be considerated a projection of self or a reflection of the mind. The personality of the artist, which includes the unconscious, is represented in the self-portrait. The self-portrait works as a transitional space that provides a safe area in which to process the feelings associated with emotional distress. Creating a self-portrait may allow the artist to discharge inner emotional tension through a controlled and appropriate artistic outlet. By reproducing aspects of emotional distress in symbolic form, the artist may feel more in control and can master chaotic or disturbing feelings without being overwhelmed.
