Dissociation refers to a split in consciousness, where elements of thoughts, emotions, memories, or experiences are kept separate, leading to a lack of connection between them. This can happen in people with dissociative disorders, such as dissociative identity disorder, where they may have multiple identities or personalities that take over control of their behavior and consciousness at different times.
