People who have suffered extreme trauma are more likely to report boredom than those who have had a less eventful time. The theory is that they shut down emotionally and find it harder to work out what they need. They may be left with free-floating desire, without knowing what to pin it on. This lack of emotional awareness is known as alexithymia and can affect anyone. Frustrated dreamers who haven't realised their goals can expend all their emotional energy on hating themselves or the world, and find they have no attention left for anything else.
