Yes, it is not uncommon for individuals with Dissociative Identity Disorder (DID) to refer to themselves using plural pronouns such as "we," "us," and "our." This use of plural pronouns reflects the presence of multiple identities or alters within the person with DID. Each alter may have its own distinct personality, thoughts, feelings, and experiences.
For individuals with DID, the experience of self is not a singular, unified identity like it is for most people. Instead, they have a system of different identities or parts that can vary in age, gender, characteristics, and even preferences. Some alters may be more dominant and take on the role of the "host" most of the time, while others may be less active or only emerge in specific situations.
Using plural pronouns is a way for individuals with DID to acknowledge and recognize the presence of their different alters and the coexistence of multiple identities within their internal system. It is an expression of their internal diversity and the way they experience their sense of self.
It's important to approach the use of plural pronouns with sensitivity and understanding. For individuals with DID, these identities are an integral part of their coping mechanism and how they navigate their lives. Respecting their use of plural pronouns can help create a safe and supportive environment for them to discuss and explore their experiences.
