pink elephant → όραμα μεθυσμένου, παραίσθηση
"Seeing pink elephants" is a euphemism for drunken hallucination caused by alcoholic hallucinosis or delirium tremens. The term dates back to at least the early 20th century, emerging from earlier idioms about snakes and other creatures. An alcoholic character in Jack London's 1913 novel John Barleycorn is said to hallucinate "blue mice and pink elephants".
