In a cross-sectional study of the pattern of isolated sleep paralysis among the entire population of nursing students at the Neuropsychiatric Hospital in Abeokuta, Nigeria (consisting of 58 males and 37 females), 44% admitted having experienced this phenomenon. The findings largely supported the results of a similar study of Nigerian medical students, except that there was a slight male preponderance among those who had the experience. Visual hallucination was the most common perceptual problem associated with the episodes, and all the affected subjects were most distressed by the experience. Whereas sleep paralysis in this country has not been found to be significantly associated with psychosocial distress or differences in personality profile, the popular view in Africa and the United States is that it is caused by witchcraft.
在对尼日利亚阿贝奥库塔神经精神病医院全体护理专业学生（包括58名男性和37名女性）进行的一项关于孤立性睡眠麻痹模式的横断面研究中，44%的人承认经历过这种现象。研究结果在很大程度上支持了一项针对尼日利亚医科学生的类似研究的结果，只是在有此经历的人群中男性略占多数。视幻觉是与这些发作相关的最常见感知问题，所有受影响的受试者都对这种经历深感苦恼。尽管在该国尚未发现睡眠麻痹与心理社会困扰或人格特征差异有显著关联，但在非洲和美国，普遍观点认为它是由巫术引起的。
