Despite the high prevalence of hypnopompic hallucinations in the community, to our knowledge there are no reports that have been published in the English literature of these phenomenon observed by staff in the hospital setting. Psychiatric or neurological evaluation often ensues if a patient reports hallucinations in other circumstances, but when they are reported in connection with sleep, further evaluation is rarely performed because such events are common in the general populace. Our report emphasizes the distinction between hypnopompic and hypnagogic hallucination as an ongoing feature of life that someone is aware of, which we believe to be the case for normal persons who have them, and a similar hallucination occurring for the first time in someone who is unaware of it, at least unable to remember it. In the latter instance, we suggest careful interview for symptoms of a sleep disorder.
