Dissociation involves a vertical splitting of the ego that results in two or more self states that are more or less organised and independently functioning. they alternate in consciousness ..and emerge separately to think, behave, remember and feel. Such dissociated states are unavailable to the rest of the personality….., creating what are known familiarly as “Jekyll and Hyde” alternations in states of mind, behaviour, and consciousness which cannot be brought together (at that time). Or a person may have less dramatic and hard to identify separations between parts of themselves that were acceptable and unacceptable to their early caregivers. The dissociated self state’s presence is felt through inexplicable or recurrent intrusive images, symptoms and actions, psychosomatic conditions or recurrent nightmares, anxiety reactions, or triggered memories. This also happens in what we call post-traumatic stress disorder.
Its severe form is induced by trauma involving pain, terror or danger and helplessness. When a person’s system of self protection is overwhelmed and disorganized, the traumatic experience is dissociated and encapsulated within the person as a separate self state, disconnected from a person’s ordinary self experience. While dissociation may provide a temporarily effective defense mechanism, this kind of fragmentation produces the severance of normally integrated mind and body functions. Its consequences can be seen in debilitating symptoms produced by post traumatic stress disorder.
