Sigmund Freud skriver til sin venn Wilhelm Fliess i Berlin: (*OBS! Må oversettes*):
"Dear Wilhelm, Last night I had a dream concerning you. It was a telegraph message about your whereabouts: Via "Casa SECERNO". The way I have writen it out shows what seemed obscure and what seemed multiple. "Secerno" was clearest. My feeling about it was annoyance that you had not gone to the place I had recommended to you: Casa Kirsch."
