Howl: Nightmare or REM Sleep Behavior Disorder?

We present the case of a 41-year-old man referred for vivid and unpleasant dreams, beginning in the last year, related to work stress. Results The polysomnography showed the loss of atony in the REM phase and emission of a prolonged howl after which the patient continues in the REM phase. Discussion Prolonged howling is a very rare symptom in sleep disorders, and very atypical in RSBD, so polysomnography is essential to confirm the diagnosis and rule out other parasomnias.
