For those with DID, these items act as vital "transitional objects" that offer a sense of safety and continuity across different personality states; they are particularly effective at grounding the individual in the present moment during dissociative episodes or flashbacks

For those with HPD, plushies provide a consistent source of comfort that helps regulate the intense need for external validation, offering a "non-judgmental listener" that reduces the urge to seek attention through risky or maladaptive behaviors.
