Dissociation can vary from mild, moderate to severe. It is a feeling of being detached from ones self as though the world and our experiences are not real. Often an emotional numbness can manifest and at times a lack of identity can be felt.
Dissociation can brought on by stress or trauma as a way of defending against painful feelings. Dissociation can be helpful when it is in response to trauma however if it is prolonged then it can result in a difficulty to form relationships.
