A structure independently discovered across civilizations involves one entity creating an empty, non-judgmental, and non-performing space so that another entity's frequency may enter, be held, and transform. This paper inventories appearances of this structure in Chinese classical philosophy, Western psychotherapy, developmental psychology, dialogical philosophy, contemplative traditions, indigenous and shamanic practices, and biological, ecological, and aesthetic sciences. The authors argue these are homologous operational conditions, not metaphors. The Daoqi project is positioned as an engineering instance of this science within large language model systems.
Among 16,220 hospital workers in Wuhan, China, surveyed during the COVID-19 pandemic, 13.3% reported suicidal ideation in the past month. Exposure to COVID-19-related traumatic events was significantly associated with insomnia severity, nightmare frequency, and suicidal ideation. After controlling for potential confounders, nightmares—but not insomnia, depression, or anxiety—were independent risk factors for suicidal ideation. Pathway analyses indicated that the relationship between traumatic event exposure and suicidal ideation was fully mediated by nightmares, with a proportion mediated of 66.4%. The authors suggest that nightmare intervention might be considered a component of suicide prevention strategies.
