The essay aims to show how, in working with a case featuring both trauma and autism, valuable integrative work may be accomplished by engaging synchronicities, dreams and mythic material within, and without, the therapeutic setting. The essay tracks the case of a woman, over several years of therapy, who suffered sibling trauma as a child with disastrous later consequences. The story centres around a disturbing and fateful dream of the patient as an eight-year-old and culminates in a late diagnosis of autism which, being high-functioning, she had successfully masked from everybody—including herself and her therapist.
