What is a split in consciousness in which some thoughts occur simultaneously with and yet separately from others thoughts?

A split in consciousness, often referred to as dissociation, occurs when an individual's thoughts, feelings, or perceptions become fragmented, allowing some thoughts to operate independently from others. This phenomenon can manifest in various ways, such as daydreaming or experiencing a sense of detachment from reality. It is commonly associated with psychological conditions like dissociative disorders, where individuals may feel disconnected from their thoughts or surroundings. Such splits can serve as coping mechanisms in response to trauma or stress.
