Hallucinations are considered to be a significant symptom of psychopathology in adulthood but children also experience auditory hallucinations. Children with conduct and emotional disorders, affective syndromes, migraines, anxiety, and adjustment disorders can all have auditory hallucinations. An Australian study of children being seen by community mental health services found strong associations between auditory hallucinations in non-psychotic children and family dysfunction and break-up. The children who heard things also had significant levels of anxiety and depression. Half of the children in the study had imaginary friends.
