Somnambulism or “sleepwalking” is a well-recognized sleep disorder in humans. Somnambulism has not been observed in nonhuman primates, including apes, either in captivity or in the wild. However, it is possible that somnambulism may be present in non-human primates but currently is undetected due to limitations in expertise and methodological resources as well as research interests.
