Dissociation is a term you may have heard in conversations about trauma or mental health, but it can feel elusive or hard to describe. At its core, dissociation is a psychological response to overwhelming stress or trauma—an adaptive mechanism that allows a person to “disconnect” from experiences, emotions, or memories that feel too painful to process in the moment. While it can protect you in the short term, chronic dissociation can interfere with your ability to feel present, connect with others, and live fully in your body.
