Quote from : In the Garden of Beasts: Love, Terror, and an American Family in Hitler's Berlin Book

Germans grew reluctant to stay in communal ski lodges, fearing they might talk in their sleep. They postponed surgeries because of the lip-loosening effects of anesthetic. Dreams reflected the ambient anxiety. One German dreamed that an SA man came to his home and opened the door to his oven, which then repeated every negative remark the household had made against the government.
