https://en.wikipedia.org/wiki/Princess_Alexandra_of_BavariaPsychological issues
Notwithstanding her literary accomplishments, Alexandra suffered from a number of psychological eccentricities,[2] including a fixation with cleanliness as well as wearing only white clothes. In her early twenties, she notably developed a delusion that as a child she had swallowed a grand piano made of glass, which remained inside her. This delusion was the subject of a 2010 BBC Radio 3 programme called "The Glass Piano", written and narrated by poet Deborah Levy, with musical sound effects interspersed between commentary by psychoanalyst Susie Orbach and others.[3]
