For example, the frequency of nightmares is generally higher in people with a mental disorder, whether depression, anxiety or post-traumatic stress disorder.Ĭould frequent nightmares provide a warning about a person’s mental health risks? Some of the characteristics of a dream may yield some hints, however. In other words, dreams alone are not enough to diagnose mental illness. Autistic patients also have fairly lackluster dreams, but the reverse is not true it is not because you have this kind of dream that you are autistic or schizophrenic. People with a psychotic disorder, especially people with schizophrenia, have particular dreams that resemble their way of reasoning during the day-flat, disjointed, limited and undiversified content that portrays the dreamer in everyday life situations. Do some betray a pathology?Īttempts have been made to identify “dream types” that are characteristic of various mental disorders, but this has not gone very far. Our dreams are often bizarre and disturbing and are sometimes frightening. In an interview with Scientific American’s French-language sister publication Pour la Science, the neurologist talks about whether depression or trauma affects dreaming and whether one should worry about recurring nightmares. As part of these studies, Arnulf investigated how these disorders affect dream states. During her career, Arnulf, who is also a professor of neurology at Sorbonne University in France, has researched a broad range of sleep conditions: sleepwalking, rapid eye movement (REM) sleep behavior disorder, lucid dreaming, sleep in Parkinson’s disease and hypersomnia, or excessive daytime sleepiness. For 30 years Isabelle Arnulf, head of the sleep disorders clinic at Pitié-Salpêtrière Hospital in Paris, has studied sleep and its associated disorders.
