Escape from reality. In some instances, dissociation induces people to imagine that they have some kind of mastery over intractable environmental difficulties. Dissociation is often implicated in magical thinking or self-induced trance states. This aspect of dissociation is frequently found in abuse survivors. It is not uncommon for abused children to engage in magical thinking to retain an illusion of control over the situation (e.g., believing that they "cause" the perpetrator to act out).
Dissociation, a form of hypnotic trance, helps children survive the abuse…The abuse takes on a dream-like, surreal quality and deadened feelings and altered perceptions add to the strangeness. The whole scene does not fit into the 'real world.' It is simple to forget, easy to believe nothing happened.
