The effects of surveillance to personal liberty nicely explained: In English und auch auf deutsch.
During the war, Freud lectured on “The Censorship of Dreams” in early December 1915. Around that time, he inserted a new body of text into The Interpretation of Dreams, mapping wartime dream censorship directly onto wartime postal censorship:
Frau Dr. H. von Hug-Hellmuth (1915) has recorded a dream which is perhaps better fitted than any to justify my choice of nomenclature [for censorship]. In this example the dream-distortion adopted the same methods as the postal censorship for expunging passages which were objectionable to it. The postal censorship makes such passages unreadable by blacking them out; the dream censorship replaced them by an incomprehensible mumble.”
A fragment here: A 50-year-old “cultivated and highly esteemed lady” had (in her dream) gone to Garrison Hospital No. 1 saying that she wanted to volunteer for “service” meaning (as was evident to everyone in earshot): “love service” (Liebesdienste). To the sentry she announced, “I and many other women and girls in Vienna are ready to [mumble, mumble].” Yet everyone in the dream understood her. One of the officers: “Suppose, madam, it actually came to…(mumble).” Or later, the dreamer: “It must never happen that an elderly woman…(mumble)…a mere boy. That would be terrible.” As she walked up the staircase she heard an officer comment: “That’s a tremendous decision to make – no matter whether a woman’s young or old! Splendid of her!”
