Boredom can be a useful tool for a psychoanalyst. It can be a sign that the patient is avoiding a particular subject; that he or she is unable to talk directly about something intimate or embarrassing. Or it can mean that patient and psychoanalyst are stuck; the patient is returning again and again to some desire or grievance that the psychoanalyst is failing to tackle. A boring person might be feeling envious, and might kill a conversation – disrupting it or paralysing it – because he cannot bear to hear a helpful or compelling idea coming from someone else. Or the boring patient may be playing possum – just as there are beasts in the jungle that survive by playing dead, some people, when frightened, simply shut down. It’s also true that psychoanalyst and patient will sometimes unconsciously collude to desiccate the atmosphere between them because they fear things becoming too emotionally disturbed, or too exciting.
