What does endorheic mean?
Endorheic basin
An endorheic basin (also endoreic basin or endorreic basin) (from the , "éndon", "within" and , "rheîn", "to flow") is a limited drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. Such a basin may also be referred to as a closed or terminal basin or as an internal drainage system or interior drainage basin.
Oneiroid syndrome
Oneiroid syndrome (OS) is a condition involving dream-like disturbances of one's consciousness by vivid scenic hallucinations, accompanied by catatonic symptoms (either catatonic stupor or excitement), delusions, or psychopathological experiences of a kaleidoscopic nature. The term is from Ancient Greek "ὄνειρος" ("óneiros", meaning "dream") and "εἶδος" ("eîdos", meaning "form, likeness"; literally "dream-like" / "oneiric or oniric", sometimes called "nightmare-like"). It is a common complication of catatonic schizophrenia, although it can also be caused by other mental disorders. The dream-like experiences are vivid enough to seem real to the patient. OS is distinguished from delirium by the fact that the imaginative experiences of patients always have an internal projection. This syndrome is hardly mentioned in standard psychiatric textbooks because it comes from a phenomenological approach, in contrast to the American attitude, which deals with detailed clinical descriptions.
