Along with the dissociation and multiple or split personalities, people with dissociative disorders may experience any of the following symptoms:
- Depression
- Mood swings
- Suicidal tendencies
- Sleep disorders (insomnia, night terrors, and sleep walking)
- Anxiety, panic attacks, and phobias (flashbacks, reactions to stimuli or "triggers")
- Alcohol and drug abuse
- Compulsions and rituals
- Psychotic-like symptoms (including auditory and visual hallucinations)
- Eating disorders
Other symptoms of dissociative identity disorder may include headache, amnesia, time loss, trances, and "out of body experiences." Some people with dissociative disorders have a tendency toward self-persecution, self-sabotage, and even violence (both self-inflicted and outwardly directed). As an example, someone with dissociative identity disorder may find themselves doing things they wouldn't normally do such as speeding, reckless driving, or stealing money from their employer or friend, yet they feel they are being compelled to do it. Some describe this feeling as being a passenger in their body rather than the driver. In other words, they truly believe they have no choice.
