You discover that you are not living, that you are hibernating. The symptoms of hibernating are easily detectable: first, restlessness. The second symptom, absence of pleasure. That is all. It appears like an illness- monotony, boredom, and death. Millions live like this, or die like this, without knowing. And then some shock treatment takes place- a person, a book, a song, and then it awakens them and saves them from death.
